3 Description

The TMS320F280013x (F280013x) is a member of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices designed for efficiency in power electronics. The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 120 MHz of signal- processing performance for floating- or fixed-point code running from either on-chip flash or SRAM. The C28x CPU is further boosted by the Trigonometric Math Unit (TMU), speeding up common algorithms key to real-time control systems. The F280013x supports up to 256KB (128KW) of flash memory. Up to 36KB (18KW) of on-chip SRAM is also available to supplement the flash memory. High-performance analog blocks are integrated into the F280013x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide optimal real-time signal chain performance. Fourteen PWM channels enable control of various power stages from a 3-phase inverter to power-factor correction and other advanced multilevel power topologies. Interfacing is supported through various industry-standard communication ports (such as SPI, SCI, I2C, and CAN) and offers multiple pin-muxing options for optimal signal placement.

TMS 38 38 29 30 18 I/O JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK. This device does not have a TRSTn pin. An external pullup resistor (recommended 2.2 kΩ) on the TMS pin to VDDIO should be placed on the board to keep JTAG in reset during normal operation. XRSn 3 3 3 3 1 I/OD Device Reset (in) and Watchdog Reset (out). During a power-on condition, this pin is driven low by the device. An external circuit may also drive this pin to assert a device reset. This pin is also driven low by the MCU when a watchdog reset occurs. During watchdog reset, the XRSn pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. A resistor between 2.2 kΩ and 10 kΩ should be placed between XRSn and VDDIO. If a capacitor is placed between XRSn and VSS for noise filtering, it should be 100 nF or smaller. These values will allow the watchdog to properly drive the XRSn pin to VOL within 512 OSCCLK cycles when the watchdog reset is asserted. This pin is an open-drain output with an internal pullup. If this pin is driven by an external device, it should be done using an open-drain device. POWER AND GROUND VDD 4, 44, 59 4, 44, 59 35, 44 36, 45 24 1.2-V Digital Logic Power Pins.

Table 5-5. Test, JTAG, and Reset SIGNAL NAME PIN TYPE DESCRIPTION 64 VPM 64 PM 48 RGZ 48 PT 32 RHB TCK I JTAG test clock with internal pullup. 36 36 27 28 16 TMS I/O JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked into the TAP controller on the rising edge of TCK. This device does not have a TRSTn pin. An external pullup resistor (recommended 2.2 kΩ) on the TMS pin to VDDIO should be placed on the board to keep JTAG in reset during normal operation. 38 38 29 30 18 XRSn I/OD Device Reset (in) and Watchdog Reset (out). During a power-on condition, this pin is driven low by the device. An external circuit may also drive this pin to assert a device reset. This pin is also driven low by the MCU when a watchdog reset occurs. During watchdog reset, the XRSn pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. A resistor between 2.2 kΩ and 10 kΩ should be placed between XRSn and VDDIO. If a capacitor is placed between XRSn and VSS for noise filtering, it should be 100 nF or smaller. These values will allow the watchdog to properly drive the XRSn pin to VOL within 512 OSCCLK cycles when the watchdog reset is asserted. This pin is an open-drain output with an internal pullup. If this pin is driven by an external device, it should be done using an open- drain device. 3 3 3 3 1

5.4.2 Digital Inputs on ADC Pins (AIOs)

GPIOs on port H are multiplexed with analog pins. These are also referred to as AIOs. These pins can only function in input mode. By default, these pins will function as analog pins and the GPIOs are in a high-Z state. The GPHAMSEL register is used to configure these pins for digital or analog operation. Note If digital signals with sharp edges (high dv/dt) are connected to the AIOs, cross-talk can occur with adjacent analog signals. The user should therefore limit the edge rate of signals connected to AIOs if adjacent channels are being used for analog functions.

5.4.3 Digital Inputs and Outputs on ADC Pins (AGPIOs)

Some GPIOs are multiplexed with analog pins and have digital input and output functionality. These are also referred to as AGPIOs. Unlike AIOs, AGPIOs have full input and output capability. By default, the AGPIOs are not connected and must be configured. Table 5-7 shows how to configure the AGPIOs. To enable the analog functionality, set the register AGPIOCTRLx from analog subsystem. To enable the digital functionality, set the register GPxAMSEL from the General-Purpose Input/Output (GPIO) chapter. Table 5-7. AGPIO Configuration AGPIOCTRLx.GPIOy (Default = 0) GPxAMSEL.GPIOy (Default = 1) Pin Connected To: ADC GPIOy 0 0 - Yes 0 1 - (1) (1) 1 0 - Yes 1 1 Yes - (1) By default there are no signals connected to AGPIO pins. One of the other rows in the table must be chosen for pin functionality. Note If digital signals with sharp edges (high dv/dt) are connected to the AGPIOs, cross-talk can occur with adjacent analog signals. The user can therefore limit the edge rate of signals connected to AGPIOs, if adjacent channels are being used for analog functions.

5.4.4 GPIO Input X-BAR

The Input X-BAR is used to route signals from a GPIO to many different IP blocks such as the ADCs, eCAPs, ePWMs, and external interrupts (see Figure 5-6 ). Table 5-8 lists the input X-BAR destinations. For details on configuring the Input X-BAR, see the Crossbar (X-BAR) chapter of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 35 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

5.6 Pins With Internal Pullup and Pulldown

Some pins on the device have internal pullups or pulldowns. Table 5-10 lists the pull direction and when it is active. The pullups on GPIO pins are disabled by default and can be enabled through software. To avoid any floating unbonded inputs, the Boot ROM will enable internal pullups on GPIO pins that are not bonded out in a particular package. Other pins noted in Table 5-10 with pullups and pulldowns are always on and cannot be disabled. Table 5-10.

6.4.5 Reducing Current Consumption

The F280013x devices provide some methods to reduce the device current consumption:

One of the two low-power modes—IDLE or STANDBY—could be entered during idle periods in the application.
The flash module may be powered down if the code is run from RAM.
Disable the pullups on pins that assume an output function.
Each peripheral has an individual clock-enable bit (PCLKCRx). Reduced current consumption may be achieved by turning off the clock to any peripheral that is not used in a given application. Section 6.4.5.1 lists the typical current reduction that may be achieved by disabling the clocks using the PCLKCRx register.
To realize the lowest VDDA current consumption in an LPM, see the Analog-to-Digital Converter (ADC) chapter of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual to ensure each module is powered down as well.

6.10 Thermal Design Considerations

Based on the end application design and operational profile, the I DD and I DDIO currents could vary. Systems that exceed the recommended maximum power dissipation in the end product may require additional thermal enhancements. Ambient temperature (T A) varies with the end application and product design. The critical factor that affects reliability and functionality is T J, the junction temperature, not the ambient temperature. Hence, care should be taken to keep T J within the specified limits. T case should be measured to estimate the operating junction temperature TJ. Tcase is normally measured at the center of the package top-side surface. The thermal application report Semiconductor and IC Package Thermal Metrics helps to understand the thermal metrics and definitions. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 51 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

6.11 System

6.11.1 Power Management Module (PMM)

6.11.1.1 Introduction

The Power Management Module (PMM) handles all the power management functions required for device operation.

6.11.1.2 Overview

The block diagram of the PMM is shown in Figure 6-4 . As can be seen, the PMM comprises of various subcomponents, which are described in the subsequent sections. MCU I/O BOR VDDIO VDD VSS XRSn EN I/O POR VDD POR 1.2v LDO VREG EN RISE DELAY (80us) OUT IN RISE DELAY (40us) Internal All Monitors Release Signal VSS CVDDIO CVDD PMM Internal External Internal External To Rest of Chip VMONCTL.bit.BORLVMONDIS CPU Reset Release VREGENZ Figure 6-4. PMM Block Diagram

6.11.1.2.1 Power Rail Monitors

The PMM has voltage monitors on the supply rails that release the XRSn signal high once the voltages cross the set threshold during power up. They also function to trip the XRSn signal low if any of the voltages drop below the programmed levels. The various voltage monitors are described in subsequent sections. Note Not all the voltage monitors are supported for device operation in an application after boot up. In the case where a voltage monitor is not supported, an external supervisor is recommended if the device needs supply voltage monitoring while the application is running. TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 www.ti.com

The three voltage monitors (I/O POR, I/O BOR, VDD POR) all have to release their respective outputs before the device begins operation (that is, XRSn goes high). However, if any of the voltage monitors trips, XRSn is driven low. The I/Os are held in high impedance when any of the voltage monitors trip. The I/O POR monitor supervises the VDDIO rail. During power up, this is the first monitor to release (that is, first to untrip) on VDDIO. The I/O BOR monitor also supervises the VDDIO rail. During power up, this is the second monitor to release (that is, second to untrip) on VDDIO. This monitor has a tighter tolerance compared to the I/O POR. Any drop in voltage below the recommended operating voltages will trip the I/O BOR and reset the device but this can be disabled by setting VMONCTL.bit.BORLVMONDIS to 1. The I/O BOR can only be disabled after the device has fully booted up. If the I/O BOR is disabled, the I/O POR will reset the device for voltage drops. Note The level at which the I/O POR trips is well below the minimum recommended voltage for VDDIO, and therefore should not be used for device supervision. Figure 6-5 shows the operating region of the I/O BOR.

I/O BOR Operating Region The VDD POR monitor supervises the VDD rail. During power up, this monitor releases (that is, untrips) once the voltage crosses the programmed trip level on VDD. Note VDD POR is programmed at a level below the minimum recommended voltage for VDD, and therefore it should not be relied upon for VDD supervision if that is required in the application.

6.11.1.2.2 External Supervisor Usage

VDDIO Monitoring: The I/O BOR is supported for application use, so an external supervisor is not required to monitor the I/O rail. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 53 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

VDD Monitoring:

VDD supplied from the internal VREG: The VDD supply is derived from the VDDIO supply. The VREG is designed in such a way that a valid VDDIO supply(monitored by the IO BOR) implies a valid VDD supply.
VDD supplied from an external supply: The VDD POR is not supported for application use. If VDD monitoring is required by the application, an external supervisor can be used to monitor the VDD rail. Note The use of an external supervisor with the internal VREG is not supported. If VDD monitoring is required by the application, a package with a VREGENZ pin must be used to power VDD externally.

6.11.1.2.3 Delay Blocks

The delay blocks in the path of the voltage monitors work together to delay the release time between the voltage monitors and XRSn. These delays are designed to make sure that the voltages are stable when XRSn releases in external VREG mode. The delay blocks are only active during power up (that is, when VDDIO and VDD are ramping up). The delay blocks contribute to the minimum slew rates specified in Power Management Module Electrical Data and Timing for the power rails. Note The delay numbers specified in the block diagram are typical numbers. The internal VREG is supplied by the VDDIO rail and can generate the 1.2 V required to power the VDD pins. It is enabled by tying the VREGENZ pin low. Although the internal VREG eliminates the need to use an external supply for VDD, decoupling capacitors are still required on the VDD pins for VREG stability and transients. See the VDD Decoupling section for details.

6.11.1.2.5 VREGENZ

The VREGENZ (VREG disable) pin controls the state of the internal VREG. To enable the internal VREG, connect the VREGENZ pin to a logic low voltage. For applications supplying VDD externally (external VREG), disable the internal VREG by tying the VREGENZ pin high. Note Not all device packages have VREGENZ pinned out. For packages without VREGENZ, external VREG mode is not supported.

6.11.1.3 External Components

6.11.1.3.1 Decoupling Capacitors

VDDIO and VDD require decoupling capacitors for correct operation. The requirements are outlined in subsequent sections. Place a minimum amount of decoupling capacitance on VDDIO. See the C VDDIO parameter in Power Management Module Electrical Data and Timing . The actual amount of decoupling capacitance to use is a requirement of the power supply driving VDDIO. Either of the configurations outlined below is acceptable:

Configuration 1: Place a decoupling capacitor on each VDDIO pin per the CVDDIO parameter.
Configuration 2: Install a single decoupling capacitor that is the equivalent of CVDDIO * VDDIO pins. Note Having the decoupling capacitor or capacitors close to the device pins is critical.

Place a minimum amount of decoupling capacitance on VDD. See the C VDD TOTAL parameter in Power Management Module Electrical Data and Timing. In external VREG mode, the actual amount of decoupling capacitance to use is a requirement of the power supply driving VDD. Either of the configurations outlined below is acceptable:

Configuration 1: Divide CVDD TOTAL across the VDD pins.
Configuration 2: Install a single decoupling capacitor with value of CVDD TOTAL. Note Having the decoupling capacitor or capacitors close to the device pins is critical.

6.11.1.4 Power Sequencing

6.11.1.4.1 Supply Pins Ganging

Connecting all 3.3-V rails together and supplying from a single source are strongly recommended. This list includes:

VDDIO
VDDA In addition, connect all power pins to avoid leaving any unconnected. In external VREG mode, the VDD pins should be tied together and supplied from a single source. In internal VREG mode, tying the VDD pins together is optional as long as each VDD pin has a capacitor connected to pin. See the VDD Decoupling section for VDD decoupling configurations. The analog modules on the device have fairly high PSRR; therefore, in most cases, noise on VDDA will have to exceed the recommended operating conditions of the supply rails before the analog modules see performance degradation. Therefore, supplying VDDA separately typically offers minimal benefits. Nevertheless, for the purposes of noise improvement, placing a pi filter between VDDIO and VDDA is acceptable. Note All the supply pins per rail are tied together internally. For example, all VDDIO pins are tied together internally, all VDD pins are tied together internally, and so forth.

6.11.1.4.2 Signal Pins Power Sequence

Before powering the device, do not apply voltage larger than 0.3 V above VDDIO or 0.3 V below VSS to any digital pin and 0.3 V above VDDA or 0.3 V below VSSA to any analog pin (including VREFHI). Simply, the signal pins should only be driven after XRSn goes high, provided all the 3.3-V rails are tied together. This sequencing is still required even if VDDIO and VDDA are not tied together. CAUTION If the above sequence is violated, device malfunction and possibly damage can occur as current will flow through unintended parasitic paths in the device. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 55 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

After the times specified by VDDIO-MON-TOT-DELAY and VXRSN-PD-DELAY, XRSn will be released and the device starts the boot-up sequence. 5. The I/O BOR monitor has different release points during power up and power down. 6. During power up, both VDDIO and VDD rails have to be up before XRSn releases.
For Power Down: 1. There is no requirement between VDDIO and VDD on which should power down first; however, there is a minimum slew rate specification. 2. The I/O BOR monitor has different release points during power up and power down. 3. Any of the POR or BOR monitors that trips during power down will cause XRSn to go low after VXRSN-PD-DELAY. Note The All Monitors Release Signal is an internal signal. Note If there is an external circuit driving XRSn (for example, a supervisor), the boot-up sequence does not start until the XRSn pin is released by all internal and external sources.

For Power Down: 1. The only requirement on VDDIO during power down is the slew rate. 2. The I/O BOR monitor has different release points during power up and power down. 3. The I/O BOR tripping will cause XRSn to go low after VXRSN-PD-DELAY and also power down the Internal VREG. Note The All Monitors Release Signal is an internal signal.

The acceptable power-up sequence for the rails is summarized below. "Power up" here means the rail in question has reached the minimum recommended operating voltage. CAUTION Non-acceptable sequences leads to reliability concerns and possibly damage. For simplicity, connecting all 3.3-V rails together and following the descriptions in Supply Pins Power Sequence is recommended. Table 6-1.

Internal VREG Sequence Summary CASE RAILS POWER-UP ORDER ACCEPTABLE VDDIO VDDA A 1 2 Yes B 2 1 - C 1 1 Yes Note The analog modules on the device should only be powered after VDDA has reached the minimum recommended operating voltage. VDDIO has a minimum slew rate requirement. If the minimum slew rate is not met, XRSn might toggle a few times until VDDIO crosses the I/O BOR region. Note The toggling on XRSn has no adverse effect on the device as boot only starts once XRSn is steadily high. However if XRSn from the device is used to gate the reset signal of other ICs, then the slew rate requirement should be met to prevent this toggling. VDD has a minimum slew rate requirement in external VREG mode. If the minimum slew rate is not met, the VDD POR may release before the VDD operational minimum voltage is met and the device may not start in a properly reset state.

6.11.1.5 Recommended Operating Conditions Applicability to the PMM

As noted in the Recommended Operating Conditions table, the voltage (V IN) of all pins on the device should be kept above VSS – 0.3 V. Negative voltages below this value will inject current into the device, which could cause TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 www.ti.com

abnormal operation. Specific care should be taken for pins near the PMM. A negative voltage on these pins can cause the POR or BOR blocks to unexpectedly assert XRSn or disable the internal VREG (see the PMM Block Diagram).

Supply ramp rate faster than the maximum can trigger the on-chip ESD protection. (4) See the Power Management Module (PMM) section on possible configurations for the total decoupling capacitance. (5) TI recommends VBOR-VDDIO-GB to avoid BOR-VDDIO resets due to normal supply noise or load-transient events on the 3.3-V VDDIO system regulator. Good system regulator design and decoupling capacitance (following the system regulator specifications) are important to prevent activation of the BOR-VDDIO during normal device operation. The value of VBOR-VDDIO-GB is a system-level design consideration; the voltage listed here is typical for many applications.

(2) VPOR-VDD is significantly below the recommended operating conditions. If monitoring of VDD is needed, an external supervisor is required. (3) Supplies are considered fully ramped up after they cross the minimum recommended operating conditions for the respective rail. All POR and BOR monitors need to be released before this delay takes effect. RC network delay will add to this. (4) On power down, any of the POR or BOR monitors that trips will immediately trip XRSn. This delay is the time between any of the POR, BOR monitors tripping and XRSn going low. It is variable and depends on the ramp down rate of the supply. RC network delay will add to this. (5) This is the transient current drawn on the VDDIO rail when the internal VREG turns on. Due to this, there might be some voltage drops on the VDDIO rail when the VREG turns on which could cause the VREG to ramp up in steps. There is no detriment to the device from this but the effect can be reduced if desired by using sufficient decoupling capacitors on VDDIO or picking an LDO/DC-DC that can supply this transient current.

6.11.2 Reset Timing

XRSn is the device reset pin. It functions as an input and open-drain output. The device has a built-in power-on reset (POR) and brown-out reset (BOR) monitors. During power up, the monitor circuits keep the XRSn pin low. For more details, see the Power Management Module (PMM) section. A watchdog or NMI watchdog reset will also drive the pin low. An external open-drain circuit may drive the pin to assert a device reset. A resistor with a value from 2.2 k Ω to 10 k Ω should be placed between XRSn and VDDIO. A capacitor should be placed between XRSn and VSS for noise filtering, it should be 100 nF or smaller. These values will allow the watchdog to properly drive the XRSn pin to V OL within 512 OSCCLK cycles when the watchdog reset is asserted. Figure 6-9 shows the recommended reset circuit.

The SCCRESET and debugger reset sources do not drive XRSn; therefore, the pins used for boot mode should not be actively driven by other devices in the system.

6.11.3.4.1 Introduction

The crystal oscillator in this device is an embedded electrical oscillator that, when paired with a compatible quartz crystal (or a ceramic resonator), can generate the system clock required by the device.

6.11.3.4.2 Overview

The following sections describe the components of the electrical oscillator and crystal. The electrical oscillator in this device is a Pierce oscillator. It is a positive feedback inverter circuit that requires a tuning circuit in order to oscillate. When this oscillator is paired with a compatible crystal, a tank circuit is formed. This tank circuit oscillates at the fundamental frequency of the crystal. On this device, the oscillator is designed to operate in parallel resonance mode due to the shunt capacitor (C0) and required load capacitors (CL). Figure 6-17 illustrates the components of the electrical oscillator and the tank circuit.

[XTAL On] Crystal Rbias Pierce Inverter Figure 6-17. Electrical Oscillator Block Diagram The electrical oscillator in this device has two modes of operation: crystal mode and single-ended mode. In the crystal mode of operation, a quartz crystal with load capacitors has to be connected to X1 and X2. This mode of operation is engaged when [XTAL On] = 1, which is achieved by setting XTALCR.OSCOFF = 0 and XTALCR.SE = 0. There is an internal bias resistor for the feedback loop so an external one should not be used. Adding an external bias resistor will create a parallel resistance with the internal Rbias, moving the bias point of operation and possibly leading to clipped waveforms, out-of-specification duty cycle, and reduction in the effective negative resistance. In this mode of operation, the resultant clock on X1 is passed through a comparator (Comp) to the rest of the chip. The clock on X1 needs to meet the VIH and VIL of the comparator. See the XTAL Oscillator Characteristics table for the VIH and VIL requirements of the comparator. In the single-ended mode of operation, a clock signal is connected to X1 with X2 left unconnected. A quartz crystal should not be used in this mode. This mode is enabled when [XTAL On] = 0, which can be achieved by setting XTALCR.OSCOFF = 1 and XTALCR.SE = 1. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 71 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

In this mode of operation, the clock on X1 is passed through a buffer (Buffer) to the rest of the chip. See the X1 Input Level Characteristics When Using an External Clock Source (Not a Crystal) table for the input requirements of the buffer. The output of the electrical oscillator that is fed to the rest of the chip can be brought out on XCLKOUT for observation by configuring the CLKSRCCTL3.XCLKOUTSEL and XCLKOUTDIVSEL.XCLKOUTDIV registers. See the GPIO Muxed Pins table for a list of GPIOs that XCLKOUT comes out on. Electrically, a quartz crystal can be represented by an LCR (Inductor-Capacitor-Resistor) circuit. However, unlike an LCR circuit, crystals have very high Q due to the low motional resistance and are also very underdamped. Components of the crystal are shown in Figure 6-18 and explained below. Cm Rm Lm C0 CL Quartz Crystal ExternalInternal Figure 6-18. Crystal Electrical Representation Cm (Motional capacitance): Denotes the elasticity of the crystal. Rm (Motional resistance): Denotes the resistive losses within the crystal. This is not the ESR of the crystal but can be approximated as such depending on the values of the other crystal components. Lm (Motional inductance): Denotes the vibrating mass of the crystal. C0 (Shunt capacitance): The capacitance formed from the two crystal electrodes and stray package capacitance. CL (Load capacitance): This is the effective capacitance seen by the crystal at its electrodes. It is external to the crystal. The frequency ppm specified in the crystal data sheet is usually tied to the CL parameter. Note that most crystal manufacturers specify CL as the effective capacitance seen at the crystal pins, while some crystal manufacturers specify CL as the capacitance on just one of the crystal pins. Check with the crystal manufacturer for how the CL is specified in order to use the correct values in calculations. From Figure 6-17, CL1 and CL2 are in series; so, to find the equivalent total capacitance seen by the crystal, the capacitance series formula has to be applied which simply evaluates to [CL1]/2 if CL1 = CL2. It is recommended that a stray PCB capacitance be added to this value. 3 pF to 5 pF are reasonable estimates, but the actual value will depend on the PCB in question. Note that the load capacitance is a requirement of both the electrical oscillator and crystal. The value chosen has to satisfy both the electrical oscillator and the crystal.

The effect of CL on the crystal is frequency-pulling. If the effective load capacitance is lower than the target, the crystal frequency will increase and vice versa. However, the effect of frequency-pulling is usually very minimal and typically results in less than 10-ppm variation from the nominal frequency. On this device, X1 and X2 can be used as GPIO19 and GPIO18, respectively, depending on the operating mode of the XTAL. Refer to the External Oscillator (XTAL) section of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual .

6.11.3.4.3 Functional Operation

Effective Series Resistance is the resistive load the crystal presents to the electrical oscillator at resonance. The higher the ESR, the lower the Q, and less likely the crystal will start up or maintain oscillation. The relationship between ESR and the crystal components is indicated below. E SR = Rm * 1 + C 0 CL 2 (2) Note that ESR is not the same as motional resistance of the crystal, but can be approximated as such if the effective load capacitance is much greater than the shunt capacitance. Negative resistance is the impedance presented by the electrical oscillator to the crystal. It is the amount of energy the electrical oscillator must supply to the crystal to overcome the losses incurred during oscillation. Rneg depicts a circuit that provides rather than consume energy and can also be viewed as the overall gain of the circuit. The generally accepted practice is to have Rneg > 3x ESR to 5x ESR to ensure the crystal starts up under all conditions. Note that it takes slightly more energy to start up the crystal than it does to sustain oscillation; therefore, if it can be ensured that the negative resistance requirement is met at start-up, then oscillation sustenance will not be an issue. Figure 6-19 and Figure 6-20 show the variation between negative resistance and the crystal components for this device. As can be seen from the graphs, the crystal shunt capacitance (C0) and effective load capacitance (CL) greatly influence the negative resistance of the electrical oscillator. Note that these are typical graphs; so, refer to Table 6-6 for minimum and maximum values for design considerations. Start-up time is an important consideration when selecting the components of the crystal circuit. As mentioned in the Rneg – Negative Resistance section, for reliable start-up across all conditions, it is recommended that the Rneg > 3x ESR to 5x ESR of the crystal. Crystal ESR and the dampening resistor (Rd) greatly affect the start-up time. The higher the two values, the longer the crystal takes to start up. Longer start-up times are usually a sign that the crystal and components are not a correct match. Refer to Crystal Oscillator Specifications for the typical start-up times. Note that the numbers specified here are typical numbers provided for guidance only. Actual start-up time depends heavily on the crystal in question and the external components. On this device, the GPIO19/18 alternate functionality on X1/X2 can be used to speed up the start-up time of the crystal if needed. This functionality is achieved by preconditioning the load capacitors CL1 and CL2 to a known state before the XTAL is turned on. See the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual for details. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 73 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

Drive level refers to how much power is provided by the electrical oscillator and dissipated by the crystal. The maximum drive level specified in the crystal manufacturer’s data sheet is usually the maximum the crystal can dissipate without damage or significant reduction in operating life. On the other hand, the drive level specified by the electrical oscillator is the maximum power it can provide. The actual power provided by the electrical oscillator is not necessarily the maximum power and depends on the crystal and board components. For cases where the actual drive level from the electrical oscillator exceeds the maximum drive level specification of the crystal, a dampening resistor (Rd) should be installed to limit the current and reduce the power dissipated by the crystal. Note that Rd reduces the circuit gain; and therefore, the actual value to use should be evaluated to make sure all other conditions for start-up and sustained oscillation are met.

6.11.3.4.4 How to Choose a Crystal

Using Crystal Oscillator Specifications as a reference: 1. Pick a crystal frequency (for example, 20 MHz). 2. Check that the ESR of the crystal <=50 Ω per specifications for 20 MHz. 3. Check that the load capacitance requirement of the crystal manufacturer is within 6 pF and 12 pF per specifications for 20 MHz.

As mentioned, CL1 and CL2 are in series; so, provided CL1 = CL2, effective load capacitance CL = [CL1]/2.
Adding board parasitics to this results in CL = [CL1]/2 + Cstray 4. Check that the maximum drive level of the crystal >= 1 mW. If this requirement is not met, a dampening resistor Rd can be used. Refer to DL – Drive Level on other points to consider when using Rd.

6.11.3.4.5 Testing

It is recommended that the user have the crystal manufacturer completely characterize the crystal with their board to ensure the crystal always starts up and maintains oscillation. Below is a brief overview of some measurements that can be performed: Due to how sensitive the crystal circuit is to capacitance, it is recommended that scope probes not be connected to X1 and X2. If scope probes must be used to monitor X1/X2, an active probe with less than 1pF input capacitance should be used. Frequency 1. Bring out the XTAL on XCLKOUT. 2. Measure this frequency as the crystal frequency. Negative Resistance 1. Bring out the XTAL on XCLKOUT. 2. Place a potentiometer in series with the crystal between the load capacitors. 3. Increase the resistance of the potentiometer until the clock on XCLKOUT stops. 4. This resistance plus the crystal’s actual ESR is the negative resistance of the electrical oscillator. Start-Up Time 1. Turn off the XTAL. 2. Bring out the XTAL on XCLKOUT. 3. Turn on the XTAL and measure how long it takes the clock on XCLKOUT to stay within 45% and 55% duty cycle.

6.11.3.4.6 Common Problems and Debug Tips

Go through the How to Choose a Crystal section and make sure there are no violations. Crystal Takes a Long Time to Start Up
If a dampening resistor Rd is installed, it is too high.
If no dampening resistor is installed, either the crystal ESR is too high or the overall circuit gain is too low due to high load capacitance.

6.11.3.5 Internal Oscillators

To reduce production board costs and application development time, all F280013x devices contain two independent internal oscillators, referred to as INTOSC1 and INTOSC2. By default, INTOSC2 is set as the source for the system reference clock (OSCCLK) and INTOSC1 is set as the backup clock source. Applications requiring tighter SCI baud rate matching can use the SCI baud tuning example (baud_tune_via_uart) available in C2000Ware.

A post-reflow bake can restore the unit to its original data sheet performance.

6.11.3.5.2 INTOSC2 with External Precision Resistor – ExtR

To achieve better accuracy, an external precision resistor can be used with INTOSC2. The external components required are:

100-kΩ precision resistor between ExtR pin and VSS
10-nF capacitor for noise filtering
20-μF VDDIO capacitance minimum for low noise supply and load transients Figure 6-21 shows an example illustration of these required external components. VDDIO ExtR Pin VSS 10 nF 100 k Place close to device and avoid noise coupling Figure 6-21. ExtR Example Schematic In ExtR mode, the oscillator frequency error is directly proportional to the accuracy of the ExtR resistor. The quality of the VDDIO supply directly affects the ExtR INTOSC performance. VDDIO capacitance values and circuit design must be decided with care to provide the cleanest supply possible to avoid jitter, noise, and other performance issues. Placing a resistor on the ExtR pin prevents the pin from being used as a GPIO or X1. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 77 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

Route ExtR trace as short as possible
Route ExtR to the nearest VSS pin
Place ExtR (RExtR) and CExtR on the same side as the C2000 device, with routing on the same layer only
Any adjacent GPIO pin (GPIO18, X2 for example) can be routed using the opposite side and in a different layer so as to reduce adjacent GPIO coupling
VSS connection must be tied both to VSS plane and directly to C2000 device VSS pin
VSS guard trace is recommended around the ExtR trace as shown in Figure 6-22

6.11.7 Emulation/JTAG

The JTAG (IEEE Standard 1149.1-1990 Standard Test Access Port and Boundary Scan Architecture) port has four dedicated pins: TMS, TDI, TDO, and TCK. The cJTAG (IEEE Standard 1149.7-2009 for Reduced-Pin and Enhanced-Functionality Test Access Port and Boundary-Scan Architecture) port is a compact JTAG interface requiring only two pins (TMS and TCK), which allows other device functionality to be muxed to the traditional GPIO35 (TDI) and GPIO37 (TDO) pins. Typically, no buffers are needed on the JTAG signals when the distance between the MCU target and the JTAG header is smaller than 6 inches (15.24 cm), and no other devices are present on the JTAG chain. Otherwise, each signal should be buffered. Additionally, for most JTAG debug probe operations at 10 MHz, no series resistors are needed on the JTAG signals. However, if high emulation speeds are expected (35 MHz or so), 22-Ω resistors should be placed in series on each JTAG signal. The PD (Power Detect) pin of the JTAG debug probe header should be connected to the board's 3.3-V supply. Header GND pins should be connected to board ground. TDIS (Cable Disconnect Sense) should also be connected to board ground. The JTAG clock should be looped from the header TCK output pin back to the RTCK input pin of the header (to sense clock continuity by the JTAG debug probe). This MCU does not support the EMU0 and EMU1 signals that are present on 14-pin and 20-pin emulation headers. These signals should always be pulled up at the emulation header through a pair of board pullup resistors ranging from 2.2 k Ω to 4.7 kΩ (depending on the drive strength of the debugger ports). Typically, a 2.2-kΩ value is used. Header pin RESET is an open-drain output from the JTAG debug probe header that enables board components to be reset through JTAG debug probe commands (available only through the 20-pin header). Figure 6-25 shows how the 14-pin JTAG header connects to the MCU’s JTAG port signals. Figure 6-26 shows how to connect to the 20-pin JTAG header. The 20-pin JTAG header pins EMU2, EMU3, and EMU4 are not used and should be grounded. For more information about hardware breakpoints and watchpoints, see Hardware Breakpoints and Watchpoints in CCS for C2000 devices. For more information about JTAG emulation, see the XDS Target Connection Guide. Note JTAG Test Data Input (TDI) is the default mux selection for the pin. The internal pullup is disabled by default. If this pin is used as JTAG TDI, the internal pullup should be enabled or an external pullup added on the board to avoid a floating input. In the cJTAG option, this pin can be used as GPIO. JTAG Test Data Output (TDO) is the default mux selection for the pin. The internal pullup is disabled by default.

6.11.8 GPIO Electrical Data and Timing

The peripheral signals are multiplexed with general-purpose input/output (GPIO) signals. On reset, GPIO pins are configured as inputs. For specific inputs, the user can also select the number of input qualification cycles to filter unwanted noise glitches. The GPIO module contains an Output X-BAR which allows an assortment of internal signals to be routed to a GPIO in the GPIO mux positions denoted as OUTPUTXBARx. The GPIO module also contains an Input X-BAR which is used to route signals from any GPIO input to different IP blocks such as the ADCs, eCAPs, ePWMs, and external interrupts. For more details, see the X-BAR chapter in the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual.

This glitch will be ignored by the input qualifier. The QUALPRD bit field specifies the qualification sampling period. It can vary from 00 to 0xFF. If QUALPRD = 00, then the sampling period is 1 SYSCLK cycle. For any other value "n", the qualification sampling period in 2n SYSCLK cycles (that is, at every 2n SYSCLK cycles, the GPIO pin will be sampled). B. The qualification period selected through the GPxCTRL register applies to groups of eight GPIO pins. C. The qualification block can take either three or six samples. The GPxQSELn Register selects which sample mode is used. D. In the example shown, for the qualifier to detect the change, the input should be stable for 10 SYSCLK cycles or greater. In other words, the inputs should be stable for (5 × QUALPRD × 2) SYSCLK cycles. This would ensure 5 sampling periods for detection to occur. Because external signals are driven asynchronously, an 13-SYSCLK-wide pulse ensures reliable recognition. Figure 6-30.

6.11.8.3 Sampling Window Width for Input Signals

The following section summarizes the sampling window width for input signals for various input qualifier configurations. Sampling frequency denotes how often a signal is sampled with respect to SYSCLK. Sampling frequency = SYSCLK/(2 × QUALPRD), if QUALPRD ≠ 0 Sampling frequency = SYSCLK, if QUALPRD = 0 Sampling period = SYSCLK cycle × 2 × QUALPRD, if QUALPRD ≠ 0 In the previous equations, SYSCLK cycle indicates the time period of SYSCLK. Sampling period = SYSCLK cycle, if QUALPRD = 0 In a given sampling window, either 3 or 6 samples of the input signal are taken to determine the validity of the signal. This is determined by the value written to GPxQSELn register. Case 1: Qualification using 3 samples Sampling window width = (SYSCLK cycle × 2 × QUALPRD) × 2, if QUALPRD ≠ 0 Sampling window width = (SYSCLK cycle) × 2, if QUALPRD = 0 Case 2: Qualification using 6 samples Sampling window width = (SYSCLK cycle × 2 × QUALPRD) × 5, if QUALPRD ≠ 0 Sampling window width = (SYSCLK cycle) × 5, if QUALPRD = 0 GPIOxn SYSCLK tw(GPI) Figure 6-31.

6.11.9 Interrupts

The C28x CPU has fourteen peripheral interrupt lines. Two of them (INT13 and INT14) are connected directly to CPU timers 1 and 2, respectively. The remaining twelve are connected to peripheral interrupt signals through the enhanced Peripheral Interrupt Expansion (ePIE) module. The ePIE multiplexes up to sixteen peripheral interrupts into each CPU interrupt line. It also expands the vector table to allow each interrupt to have its own ISR. This allows the CPU to support a large number of peripherals. An interrupt path is divided into three stages—the peripheral, the ePIE, and the CPU. Each stage has its own enable and flag registers. This system allows the CPU to handle one interrupt while others are pending, implement and prioritize nested interrupts in software, and disable interrupts during certain critical tasks. Figure 6-32 shows the interrupt architecture for this device.

The LPM block responds to the HALT signal, SYSCLK is held for a maximum 16 INTOSC1 clock cycles before being turned off. This delay enables the CPU pipeline and any other pending operations to flush properly. C. Clocks to the peripherals are turned off and the PLL is shut down. If a quartz crystal or ceramic resonator is used as the clock source, the internal oscillator is shut down as well. The device is now in HALT mode and consumes very little power. It is possible to keep the internal oscillators (INTOSC1 and INTOSC2) and the watchdog alive in HALT MODE. This is done by writing 1 to CLKSRCCTL1.WDHALTI. After the IDLE instruction is executed, a delay of five OSCCLK cycles (minimum) is needed before the wake-up signal could be asserted. D. When the GPIOn pin (used to bring the device out of HALT) is driven low, the oscillator is turned on and the oscillator wake-up sequence is initiated. The GPIO pin should be driven high only after the oscillator has stabilized. This enables the provision of a clean clock signal during the PLL lock sequence. Because the falling edge of the GPIO pin asynchronously begins the wake-up procedure, care should be taken to maintain a low noise environment before entering and during HALT mode. E. The wake-up signal fed to a GPIO pin to wake up the device must meet the minimum pulse width requirement. Furthermore, this signal must be free of glitches. If a noisy signal is fed to a GPIO pin, the wake-up behavior of the device will not be deterministic and the device may not exit low-power mode for subsequent wake-up pulses. F. When CLKIN to the core is enabled, the device will respond to the interrupt (if enabled), after some latency. The HALT mode is now exited. G. Normal operation resumes. H. The user must relock the PLL upon HALT wakeup to ensure a stable PLL lock. Figure 6-36.

The analog subsystem module is described in this section. The analog modules on this device include the Analog-to-Digital Converter (ADC), Temperature Sensor, Comparator Subsystem (CMPSS), and Lite Comparator Subsystem variant (CMPSS_LITE). The analog subsystem has the following features:

Flexible voltage references – The ADCs are referenced to VREFHI and VSSA pins
VREFHI pin voltage can be driven in externally or can be generated by an internal bandgap voltage reference
The internal voltage reference range can be selected to be 0 V to 3.3 V or 0 V to 2.5 V – The comparator DACs are referenced to VDDA and VSSA
Flexible pin usage – Comparator subsystem inputs and digital inputs (AIOs)/outputs (AGPIOs) are multiplexed with ADC inputs – Low comparator DAC (CMPx_DACL) can optionally be brought out to a multiplexed ADC pin for external use (mutually exclusive with use of CMPSS compare functions and only available on some CMPSS instances) – Internal connection to VREFLO on all ADCs for offset self-calibration Figure 6-37 shows the Analog Subsystem Block Diagram for all packages.

6.12.3 Analog-to-Digital Converter (ADC)

The ADC module described here is a successive approximation (SAR) style ADC with resolution of 12 bits . This section refers to the analog circuits of the converter as the “core,” and includes the channel-select MUX, the sample-and-hold (S/H) circuit, the successive approximation circuits, voltage reference circuits, and other analog support circuits. The digital circuits of the converter are referred to as the “wrapper” and include logic for programmable conversions, result registers, interfaces to analog circuits, interfaces to the peripheral buses, post-processing circuits, and interfaces to other on-chip modules. Each ADC module consists of a single sample-and-hold (S/H) circuit. The ADC module is designed to be duplicated multiple times on the same chip, allowing simultaneous sampling or independent operation of multiple ADCs. The ADC wrapper is start-of-conversion (SOC)-based (see the SOC Principle of Operation section of the Analog-to-Digital Converter (ADC) chapter in the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual). Each ADC has the following features:

Resolution of 12 bits
Ratiometric external reference set by VREFHI/VREFLO
Selectable internal reference of 2.5 V or 3.3 V
Single-ended signal mode
Input multiplexer with up to 21 channels
16 configurable SOCs
16 individually addressable result registers
Multiple trigger sources – Software immediate start – All ePWMs: ADCSOC A or B – GPIO XINT2 – CPU Timers 0/1/2 – ADCINT1/2
Four flexible PIE interrupts
Burst-mode triggering option
Four post-processing blocks, each with: – Saturating offset calibration – Error from setpoint calculation – High, low, and zero-crossing compare, with interrupt and ePWM trip capability – Trigger-to-sample delay capture Note Not every channel can be pinned out from all ADCs. See the Pin Configuration and Functions section to determine which channels are available.

6.12.3.1 ADC Configurability

Some ADC configurations are individually controlled by the SOCs, while others are globally controlled per ADC module. Table 6-16 summarizes the basic ADC options and their level of configurability. Table 6-16. ADC Options and Configuration Levels OPTIONS CONFIGURABILITY Clock Per module(1) Resolution Not configurable (12-bit resolution only) Signal mode Not configurable (single-ended signal mode only) Reference voltage source Either external or internal for all modules Trigger source Per SOC(1) Converted channel Per SOC Acquisition window duration Per SOC(1) EOC location Per module Burst mode Per module(1) (1) Writing these values differently to different ADC modules could cause the ADCs to operate asynchronously. For guidance on when the ADCs are operating synchronously or asynchronously, see the Ensuring Synchronous Operation section of the Analog-to-Digital Converter (ADC) chapter in the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual.

6.12.3.2 ADC Electrical Data and Timing

The ADC inputs should be kept below VDDA + 0.3 V. If an ADC input goes above this level ADC disturbances to other channels may occur by two mechanisms:

ADC input over-voltage will overdrive the CMPSS mux, disturbing all other channels which share a common CMPSS mux. This disturbance will be continuous regardless of if the over-voltage input is sampled by the ADC
When the ADC samples the over-voltage ADC input, VREFHI will be pulled up to a higher level. This will disturb subsequent ADC conversions on any channel until the VREF stabilizes Note The VREFHI pin must be kept below VDDA + 0.3 V to ensure proper functional operation. If the VREFHI pin exceeds this level, a blocking circuit may activate, and the internal value of VREFHI may float to 0 V internally, giving improper ADC conversion.

6.12.3.2.5 ADC Timing Diagrams

Figure 6-46 shows the ADC conversion timings for two SOCs given the following assumptions:

SOC0 and SOC1 are configured to use the same trigger.
No other SOCs are converting or pending when the trigger occurs.
The round-robin pointer is in a state that causes SOC0 to convert first.
ADCINTSEL is configured to set an ADCINT flag upon end of conversion for SOC0 (whether this flag propagates through to the CPU to cause an interrupt is determined by the configurations in the PIE module). Table 6-22 lists the descriptions of the ADC timing parameters. Table 6-23 lists the ADC timings.

ADC Timings Table 6-22. ADC Timing Parameter Descriptions Parameter Description tSH The duration of the S+H window. At the end of this window, the value on the S+H capacitor becomes the voltage to be converted into a digital value. The duration is given by (ACQPS + 1) SYSCLK cycles. ACQPS can be configured individually for each SOC, so tSH is not necessarily the same for different SOCs. Note: The value on the S+H capacitor is captured approximately 5 ns before the end of the S+H window regardless of device clock settings. tLAT The time from the end of the S+H window until the ADC results latch in the ADCRESULTx register. If the ADCRESULTx register is read before this time, the previous conversion results are returned.

Table 6-22. ADC Timing Parameter Descriptions (continued) Parameter Description tEOC The time from the end of the S+H window until the S+H window for the next ADC conversion can begin. The subsequent sample can start before the conversion results are latched. tINT The time from the end of the S+H window until an ADCINT flag is set (if configured). If the INTPULSEPOS bit in the ADCCTL1 register is set, tINT coincides with the end of conversion (EOC) signal. If the INTPULSEPOS bit is 0, tINT coincides with the end of the S+H window. If tINT triggers a read of the ADC result register (by triggering an ISR that reads the result), care must be taken to make sure the read occurs after the results latch (otherwise, the previous results are read). If the INTPULSEPOS bit is 0, and the OFFSET field in the ADCINTCYCLE register is not 0, then there is a delay of OFFSET SYSCLK cycles before the ADCINT flag is set. This delay can be used to enter the ISR exactly when the sample is ready. Table 6-23. ADC Timings in 12-bit Mode ADCCLK Prescale SYSCLK Cycles ADCCTL2.

6.12.5 Comparator Subsystem (CMPSS)

The Comparator Subsystem (CMPSS) consists of analog comparators and supporting circuits that are useful for power applications such as peak current mode control, switched-mode power supply, power factor correction, voltage trip monitoring, and so forth. This device contains two variants of the CMPSS module: CMPSS and CMPSS_LITE. These modules share a common architecture, but some features are supported only by the full CMPSS variant and not the CMPSS_LITE variant. The comparator subsystem is built around a number of modules. Each subsystem contains two comparators, two reference 12-bit DACs (CMPSS_LITE instances are 9.5-bit effective reference DACs) , and two digital filters. The subsystem also includes one ramp generator (full CMPSS modules only; not supported by CMPSS_LITE instances). Comparators are denoted "H" or "L" within each module where “H” and “L” represent high and low, respectively. Each comparator generates a digital output which indicates whether the voltage on the positive input is greater than the voltage on the negative input. The positive input of the comparator is driven from an external pin (see the Analog Subsystem chapter of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual for mux options available to the CMPSS). The negative input can be driven by an external pin or by the programmable reference 12-bit DAC. Each comparator output passes through a programmable digital filter that can remove spurious trip signals. An unfiltered output is also available if filtering is not required. A ramp generator circuit is optionally available to control the reference 12-bit DAC value for the high comparator in the subsystem (full CMPSS modules only; not supported by CMPSS_LITE instances). Each CMPSS includes:

Two analog comparators
Two programmable reference 12-bit DACs (9.5-bit effective DACs on CMPSS_LITE instances)
One ramp generator (full CMPSS only; not available on CMPSS_LITE instances)
Two digital filters, 65536 max filter clock prescale
Ability to synchronize submodules with EPWMSYNCPER
Ability to extend clear signal with EPWMBLANK
Ability to synchronize output with SYSCLK
Ability to latch output
Ability to invert output
Option to use hysteresis on the input
Option for negative input of comparator to be driven by an external signal or by the reference DAC
Option to use the low comparator DAC output, CMPx_DACL, on an external pin (select instances only, mutually exclusive with use of compare functionality)

6.12.5.1 CMPSS Module Variants

This device contains two different variants of the CMPSS module: CMPSS (full module) and the CMPSS_LITE (reduced functionality and performance). The differences in features between the two variants are summarized in Table 6-24. Table 6-24.

6.12.5.2 CMPx_DACL

Some CMPSS module instances have support for DAC output buffered to a pin. This CMPx_DACL output from the CMPSS module uses the low-side DAC of the CMPSS module specified. When using DAC output from a CMPSS instance, all other CMPSS module features for that instance are unavailable. For CMPx_DACL instances available for a particular device, please see the DAC column of the Analog Pins and Internal Connections table. See the Buffered Output from CMPx_DACL Electrical Characteristics section for DAC output capabilities.

When using the ramp generator to control the internal DAC, the step size can vary based on the application need. Since the step size of the DAC is less than a full scale transition, the settling time is improved from the electrical specification listed in the CMPSS DAC Static Electrical Characteristics table. The equation below and Figure 6-56 can give guidance on the expected voltage error from ideal based on different RAMPxDECVALA values.

6.13 Control Peripherals

6.13.1 Enhanced Pulse Width Modulator (ePWM)

The ePWM peripheral is a key element in controlling many of the power electronic systems found in both commercial and industrial equipment. The ePWM type-4 module is able to generate complex pulse width waveforms with minimal CPU overhead by building the peripheral up from smaller modules with separate resources that can operate together to form a system. Some of the highlights of the ePWM type-4 module include complex waveform generation, dead-band generation, a flexible synchronization scheme, advanced trip-zone functionality, and global register reload capabilities. The ePWM and eCAP synchronization scheme on the device provides flexibility in partitioning the ePWM and eCAP modules and allows localized synchronization within the modules. Figure 6-57 shows the ePWM module. Figure 6-58 shows the ePWM trip input connectivity. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 125 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

6.13.2 High-Resolution Pulse Width Modulator (HRPWM)

The HRPWM combines multiple delay lines in a single module and a simplified calibration system by using a dedicated calibration delay line. For each ePWM module, there are two HR outputs:

HR Duty and Deadband control on Channel A
HR Duty and Deadband control on Channel B The HRPWM module offers PWM resolution (time granularity) that is significantly better than what can be achieved using conventionally derived digital PWM methods. The key points for the HRPWM module are:
Significantly extends the time resolution capabilities of conventionally derived digital PWM
This capability can be used in both single edge (duty cycle and phase-shift control) as well as dual edge control for frequency/period modulation.
Finer time granularity control or edge positioning is controlled through extensions to the Compare A, B, phase, period and deadband registers of the ePWM module.

MEP step size will increase with higher temperature and lower voltage and decrease with lower temperature and higher voltage. Applications that use the HRPWM feature should use MEP Scale Factor Optimizer (SFO) estimation software functions. See the TI software libraries for details of using SFO functions in end applications. SFO functions help to estimate the number of MEP steps per SYSCLK period dynamically while the HRPWM is in operation.

6.13.4 Enhanced Capture (eCAP)

The features of the eCAP module include:

Speed measurements of rotating machinery (for example, toothed sprockets sensed by way of Hall sensors)
Elapsed time measurements between position sensor pulses
Period and duty cycle measurements of pulse train signals
Decoding current or voltage amplitude derived from duty cycle encoded current/voltage sensors The eCAP module features described in this chapter include:
4-event time-stamp registers (each 32 bits)
Edge polarity selection for up to four sequenced time-stamp capture events
Interrupt on either of the four events
Single-shot capture of up to four event time-stamps
Continuous mode capture of time stamps in a four-deep circular buffer
Absolute time-stamp capture
Difference (Delta) mode time-stamp capture
When not used in capture mode, the eCAP module can be configured as a single-channel PWM output The capture functionality of the Type 1 eCAP is enhanced from the Type 0 eCAP with the following added features:
Event filter reset bit – Writing a 1 to ECCTL2[CTRFILTRESET] clears the event filter, the modulo counter, and any pending interrupts flags. Resetting the bit is useful for initialization and debug.
Modulo counter status bits – The modulo counter (ECCTL2 [MODCNTRSTS]) indicates which capture register is loaded next. In the Type 0 eCAP, to know the current state of the modulo counter was not possible
Input multiplexer – ECCTL0 [INPUTSEL] selects one of 128 input signals, which are detailed in the Configuring Device Pins for the eCAP section of the Enhanced Capture (eCAP) chapter in the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual.
EALLOW protection – EALLOW protection was added to critical registers. To maintain software compatibility with Type-0, configure DEV_CFG_REGS.ECAPTYPE to make these registers unprotected. The capture functionality of the Type 2 eCAP is enhanced from the Type 1 eCAP with the following added features:
Added ECAPxSYNCINSEL register – ECAPxSYNCINSEL register is added for each eCAP to select an external SYNCIN. Every eCAP can have a separate SYNCIN signal. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 131 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

6.14.2.1 I2C Electrical Data and Timing

To meet all of the I2C protocol timing specifications, the I2C module clock must be configured in the range from 7 MHz to 12 MHz. A pullup resistor must be chosen to meet the I2C standard timings. In most circumstances, 2.2 k Ω of total bus resistance to VDDIO is sufficient. For evaluating pullup resistor values for a particular design, see the I2C Bus Pullup Resistor Calculation Application Report.

6.14.3 Serial Communications Interface (SCI)

The SCI is a 2-wire asynchronous serial port, commonly known as a UART. The SCI module supports digital communications between the CPU and other asynchronous peripherals that use the standard non-return-to-zero (NRZ) format The SCI receiver and transmitter each have a 16-level-deep FIFO for reducing servicing overhead, and each has its own separate enable and interrupt bits. Both can be operated independently for half-duplex communication, or simultaneously for full-duplex communication. To specify data integrity, the SCI checks received data for break detection, parity, overrun, and framing errors. The bit rate is programmable to different speeds through a 16-bit baud-select register. Features of the SCI module include:

Two external pins: – SCITXD: SCI transmit-output pin – SCIRXD: SCI receive-input pin – Baud rate programmable to 64K different rates
Data-word format – 1 start bit – Data-word length programmable from 1 to 8 bits – Optional even/odd/no parity bit – 1 or 2 stop bits
Four error-detection flags: parity, overrun, framing, and break detection
Two wake-up multiprocessor modes: idle-line and address bit
Half- or full-duplex operation
Double-buffered receive and transmit functions
Transmitter and receiver operations can be accomplished through interrupt-driven or polled algorithms with status flags. – Transmitter: TXRDY flag (transmitter-buffer register is ready to receive another character) and TX EMPTY flag (transmitter-shift register is empty) – Receiver: RXRDY flag (receiver-buffer register is ready to receive another character), BRKDT flag (break condition occurred), and RX ERROR flag (monitoring four interrupt conditions)
Separate enable bits for transmitter and receiver interrupts (except BRKDT)
NRZ format
Auto baud-detect hardware logic
16-level transmit and receive FIFO Note All registers in this module are 8-bit registers. When a register is accessed, the register data is in the lower byte (bits 7–0), and the upper byte (bits 15–8) is read as zeros. Writing to the upper byte has no effect. Figure 6-68 shows the SCI block diagram. TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 www.ti.com

6.14.4 Serial Peripheral Interface (SPI)

The serial peripheral interface (SPI) is a high-speed synchronous serial input and output (I/O) port that allows a serial bit stream of programmed length (1 to 16 bits) to be shifted into and out of the device at a programmed bit- transfer rate. The SPI is normally used for communications between the MCU controller and external peripherals or another controller. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers, and analog-to-digital converters (ADCs). Multidevice communications are supported by the master or slave operation of the SPI. The port supports a 16-level, receive and transmit FIFO for reducing CPU servicing overhead. The SPI module features include:

SPISOMI: SPI slave-output/master-input pin
SPISIMO: SPI slave-input/master-output pin
SPISTE: SPI slave transmit-enable pin
SPICLK: SPI serial-clock pin
Two operational modes: Master and Slave
Baud rate: 125 different programmable rates. The maximum baud rate that can be employed is limited by the maximum speed of the I/O buffers used on the SPI pins.
Data word length: 1 to 16 data bits
Four clocking schemes (controlled by clock polarity and clock phase bits) include: – Falling edge without phase delay: SPICLK active-high. SPI transmits data on the falling edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal. – Falling edge with phase delay: SPICLK active-high. SPI transmits data one half-cycle ahead of the falling edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal. – Rising edge without phase delay: SPICLK inactive-low. SPI transmits data on the rising edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal. – Rising edge with phase delay: SPICLK inactive-low. SPI transmits data one half-cycle ahead of the rising edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal.
Simultaneous receive and transmit operation (transmit function can be disabled in software)
Transmitter and receiver operations are accomplished through either interrupt-driven or polled algorithm
16-level transmit/receive FIFO
High-speed mode
Delayed transmit control
3-wire SPI mode
SPISTE inversion for digital audio interface receive mode on devices with two SPI modules Figure 6-69 shows the SPI CPU interfaces. TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 www.ti.com

7 Detailed Description

7.1 Overview

The TMS320F280013x (F280013x) is a member of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices designed for efficiency in power electronics. The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 120 MHz of signal- processing performance for floating- or fixed-point code running from either on-chip flash or SRAM. The C28x CPU is further boosted by the Trigonometric Math Unit (TMU), speeding up common algorithms key to real-time control systems. The F280013x supports up to 256KB (128KW) of flash memory. Up to 36KB (18KW) of on-chip SRAM is also available to supplement the flash memory. High-performance analog blocks are integrated into the F280013x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide optimal real-time signal chain performance. Fourteen PWM channels enable control of various power stages from a 3-phase inverter to power-factor correction and other advanced multilevel power topologies. Interfacing is supported through various industry-standard communication ports (such as SPI, SCI, I2C, and CAN) and offers multiple pin-muxing options for optimal signal placement.

7.3.1.1 Dedicated RAM (Mx RAM)

The CPU subsystem has two dedicated ECC-capable RAM blocks: M0 and M1. These memories are small nonsecure blocks that are tightly coupled with the CPU (that is, only the CPU has access to them).

7.3.1.2 Local Shared RAM (LSx RAM)

Local shared RAMs (LSx RAMs) are accessible to the CPU. All LSx RAM blocks have Parity. These memories are secure and have CPU access protection (CPU write/CPU fetch). TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 www.ti.com

7.3.2 Flash Memory Map

On the F280013x devices, one flash bank (256KB [128KW]) is available. Code to program the flash should be executed out of RAM, there should not be any kind of access to the flash bank when an erase or program operation is in progress. Table 7-2.

7.5 C28x Processor

The CPU is a 32-bit fixed-point processor. This device draws from the best features of digital signal processing; reduced instruction set computing (RISC); and microcontroller architectures, firmware, and tool sets. The CPU features include a modified Harvard architecture and circular addressing. The RISC features are single-cycle instruction execution, register-to-register operations, and modified Harvard architecture. The microcontroller features include ease of use through an intuitive instruction set, byte packing and unpacking, and bit manipulation. The modified Harvard architecture of the CPU enables instruction and data fetches to be performed in parallel. The CPU can read instructions and data while it writes data simultaneously to maintain the single-cycle instruction operation across the pipeline. The CPU does this over six separate address/data buses. For more information on CPU architecture and instruction set, see the TMS320C28x CPU and Instruction Set Reference Guide.

7.5.1 Floating-Point Unit (FPU)

The C28x plus floating-point (C28x+FPU) processor extends the capabilities of the C28x fixed-point CPU by adding registers and instructions to support IEEE single-precision floating-point operations. Devices with the C28x+FPU include the standard C28x register set plus an additional set of floating-point unit registers. The additional floating-point unit registers are the following:

Eight floating-point result registers, RnH (where n = 0–7)
Floating-point Status Register (STF)
Repeat Block Register (RB) All of the floating-point registers, except the RB, are shadowed. This shadowing can be used in high-priority interrupts for fast context save and restore of the floating-point registers. For more information on the C28x Floating Point Unit (FPU), see the TMS320C28x Extended Instruction Sets Technical Reference Manual.

7.5.2 Trigonometric Math Unit (TMU)

The trigonometric math unit (TMU) extends the capabilities of a C28x+FPU by adding instructions and leveraging existing FPU instructions to speed up the execution of common trigonometric and arithmetic operations listed in Table 7-5.

7.6 Device Boot Modes

This section explains the default boot modes, as well as all the available boot modes supported on this device. The boot ROM uses the boot mode select, general-purpose input/output (GPIO) pins to determine the boot mode configuration. Table 7-6 shows the boot mode options available for selection by the default boot mode select pins. Users have the option to program the device to customize the boot modes selectable in the boot-up table as well as the boot mode select pin GPIOs used. All the peripheral boot modes that are supported use the first instance of the peripheral module (SCIA, SPIA, I2CA, CANA, and so forth). Whenever these boot modes are referred to in this chapter, such as SCI boot, it is actually referring to the first module instance, which means the SCI boot on the SCIA port. The same applies to the other peripheral boots. See the Reset (XRSn) Switching Characteristics table and the Reset Timing Diagrams for t boot-flash, the boot ROM execution time to first instruction fetch in flash. Table 7-6. Device Default Boot Modes BOOT MODE GPIO24 (DEFAULT BOOT MODE SELECT PIN 1) GPIO32 (DEFAULT BOOT MODE SELECT PIN 0) Parallel IO 0 0 SCI / Wait Boot(1) 0 1 CAN 1 0 Flash 1 1 (1) SCI boot mode can be used as a wait boot mode as long as SCI continues to wait for an 'A' or 'a' during the SCI autobaud lock process. Table 7-7 lists the possible boot modes supported on the device. The default boot mode pins are GPIO24 (boot mode pin 1) and GPIO32 (boot mode pin 0). Users may choose to have weak pullups for boot mode pins if they use a peripheral on these pins as well, so the pullups can be overdriven. On this device, customers can change the factory default boot mode pins by programming user-configurable Dual Code Security Module (DCSM) OTP locations. Table 7-7.

7.6.1 Device Boot Configurations

This section details what boot configurations are available and how to configure them. This device supports from 0 boot mode select pins up to 3 boot mode select pins as well as from 1 configured boot mode up to 8 configured boot modes. To change and configure the device from the default settings to custom settings for your application, use the following process: 1. Determine all the various ways you want application to be able to boot. (For example: Primary boot option of Flash boot for your main application, secondary boot option of CAN boot for firmware updates, tertiary boot option of SCI boot for debugging, etc) 2. Based on the number of boot modes needed, determine how many boot mode select pins (BMSPs) are required to select between your selected boot modes. (For example: 2 BMSPs are required to select between 3 boot mode options) 3. Assign the required BMSPs to a physical GPIO pin. (For example, BMSP0 to GPIO10, BMSP1 to GPIO51, and BMSP2 left as default which is disabled). Refer to Section 7.6.1.1 for all the details on performing these configurations. 4. Assign the determined boot mode definitions to indexes in your custom boot table that correlate to the decoded value of the BMSPs. For example, BOOTDEF0=Boot to Flash, BOOTDEF1=CAN Boot, BOOTDEF2=SCI Boot; all other BOOTDEFx are left as default/nothing). Refer to Section 7.6.1.2 for all the details on setting up and configuring the custom boot mode table. Additionally, the Boot Mode Example Use Cases section of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual provides some example use cases on how to configure the BMSPs and custom boot tables. Note The CAN boot mode turns on the XTAL. Be sure an XTAL is installed in the application before using CAN boot mode.

7.6.1.1 Configuring Boot Mode Pins

This section explains how the boot mode select pins can be customized by the user, by programming the BOOTPIN-CONFIG location (refer to Table 7-8 ) in the user-configurable dual-zone security module (DCSM) OTP. The location in the DCSM OTP is Z1-OTP-BOOTPIN-CONFIG or Z2-OTP-BOOTPIN-CONFIG. When debugging, EMU-BOOTPIN-CONFIG is the emulation equivalent of Z1-OTP-BOOTPIN-CONFIG/Z2-OTP- BOOTPIN-CONFIG, and can be programmed to experiment with different boot modes without writing to OTP. The device can be programmed to use 0, 1, 2, or 3 boot mode select pins as needed. Note When using Z2-OTP-BOOTPIN-CONFIG, the configurations programmed in this location will take priority over the configurations in Z1-OTP-BOOTPIN-CONFIG. It is recommended to use Z1-OTP- BOOTPIN-CONFIG first and then if OTP configurations need to be altered, switch to using Z2-OTP- BOOTPIN-CONFIG. Table 7-8. BOOTPIN-CONFIG Bit Fields BIT NAME DESCRIPTION 31:24 Key Write 0x5A to these 8-bits to indicate the bits in this register are valid 23:16 Boot Mode Select Pin 2 (BMSP2) Refer to BMSP0 description except for BMSP2 15:8 Boot Mode Select Pin 1 (BMSP1) Refer to BMSP0 description except for BMSP1 7:0 Boot Mode Select Pin 0 (BMSP0) Set to the GPIO pin to be used during boot (up to 255): - 0x0 = GPIO0 - 0x01 = GPIO1 - and so on Writing 0xFF disables BMSP0 and this pin is no longer used to select the boot mode. Note GPIO 224 to 253 are analog pins, but digital inputs are possible on these pins provided the software writes to the GPIOHAMSEL register bits. The following GPIOs cannot be used as a BMSP. If selected for a particular BMSP, the boot ROM will automatically select the factory default GPIOs for BMSP0 and BMSP1. Factory default for BMSP2 is 0xFF, which disables the BMSP.

It is recommended when disabling BMSPs to start with disabling BMSP2. For example, in an instance when only using BMSP2 (BMSP1 and BMSP0 are disabled), then only the boot table indexes of 0 and 4 will be selectable. In the instance when using only BMSP0, then the selectable boot table indexes are 0 and 1.

7.6.1.2 Configuring Boot Mode Table Options

This section explains how to configure the boot definition table, BOOTDEF, for the device and the associated boot options. The 64-bit location is located in user-configurable DCSM OTP in the Z1-OTP-BOOTDEF-LOW and Z1-OTP-BOOTDEF-HIGH locations. When debugging, EMU-BOOTDEF-LOW and EMU-BOOTDEF-HIGH are the emulation equivalents of Z1-OTP-BOOTDEF-LOW and Z1-OTP-BOOTDEF-HIGH, and can be programmed to experiment with different boot mode options without writing to OTP. The range of customization to the boot definition table depends on how many boot mode select pins (BMSP) are being used. For example,

0 BMSPs equals to 1 table entry, 1 BMSP equals to 2 table entries, 2 BMSPs equals to 4 table entries,

and 3 BMSPs equals to 8 table entries. Refer to the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual for examples on how to set up the BOOTPIN_CONFIG and BOOTDEF values. Note The locations Z2-OTP-BOOTDEF-LOW and Z2-OTP-BOOTDEF-HIGH will be used instead of Z1- OTP-BOOTDEF-LOW and Z1-OTP-BOOTDEF-HIGH locations when Z2-OTP-BOOTPIN-CONFIG is Table 7-10. BOOTDEF Bit Fields BOOTDEF NAME BYTE POSITION NAME DESCRIPTION BOOT_DEF0 7:0 BOOT_DEF0 Mode/Options Set the boot mode for index 0 of the boot table. Different boot modes and their options can include, for example, a boot mode that uses different GPIOs for a specific bootloader or a different flash entry point address. Any unsupported boot mode will cause the device to either go to wait boot or boot to flash. Refer to GPIO Assignments for valid BOOTDEF values to set in the table.

7.7 Security

Security features are enforced by the Dual Code Security Module (DCSM). The primary layer of defense is securing the boundary of the chip, which should always be enabled. Additionally, the Dual Zone Security feature is available to support code partitioning.

7.7.1 Securing the Boundary of the Chip

The following two features, along with authentication in the firmware update code, should be used to help to prevent unauthorized code from running on the device.

7.7.1.1 JTAGLOCK

Enabling the JTAGLOCK feature in the USER OTP disables JTAG access (for example, debug probe) to resources on the device.

7.7.1.2 Zero-pin Boot

Enabling the Zero-pin Boot option along with Flash Boot in the USER OTP blocks all pin-based external bootloader options (for example, SCI, CAN, Parallel).

7.7.2 Dual-Zone Security

The dual-zone security mechanism offers protection for two zones: Zone 1 (Z1) and Zone 2 (Z2). The security implementation for both zones is identical. Each zone has its own dedicated secure resource (OTP memory and secure ROM) and allocated secure resource (LSx RAM and flash sectors).

7.8 Watchdog

The watchdog module is the same as the one on previous TMS320C2000™ microcontrollers, but with an optional lower limit on the time between software resets of the counter. This windowed countdown is disabled by default, so the watchdog is fully backward-compatible. The watchdog generates either a reset or an interrupt. It is clocked from the internal oscillator with a selectable frequency divider. Figure 7-2 shows the various functional blocks within the watchdog module.

7.9 C28x Timers

CPU-Timers 0, 1, and 2 are identical 32-bit timers with presettable periods and with 16-bit clock prescaling. The timers have a 32-bit count-down register that generates an interrupt when the counter reaches zero. The counter is decremented at the CPU clock speed divided by the prescale value setting. When the counter reaches zero, it is automatically reloaded with a 32-bit period value. CPU-Timer 0 is for general use and is connected to the PIE block. CPU-Timer 1 is also for general use and is connected to INT13 of the CPU. CPU-Timer 2 is reserved for TI-RTOS. It is connected to INT14 of the CPU. If TI-RTOS is not being used, CPU-Timer 2 is available for general use. CPU-Timer 2 can be clocked by any one of the following:

SYSCLK (default)
Internal oscillator 1 (INTOSC1)
Internal oscillator 2 (INTOSC2)
X1 (XTAL)

7.10 Dual-Clock Comparator (DCC)

The DCC module is used for evaluating and monitoring the clock input based on a second clock, which can be a more accurate and reliable version. This instrumentation is used to detect faults in clock source or clock structures, thereby enhancing the system's safety metrics.

7.10.1 Features

The DCC has the following features:

Allows the application to ensure that a fixed ratio is maintained between frequencies of two clock signals.
Supports the definition of a programmable tolerance window in terms of the number of reference clock cycles.
Supports continuous monitoring without requiring application intervention.
Supports a single-sequence mode for spot measurements.
Allows the selection of a clock source for each of the counters, resulting in several specific use cases.

8.3.1.1 Air-conditioner Outdoor Unit

Air-conditioner outdoor unit design considerations include maximizing power efficiency; minimizing acoustics; and cost. Variable-speed air-conditioners enable continuous temperature regulation and are more efficient than fixed-speed air-conditioners. The air-conditioner’s outdoor unit (ODU) consists of a power factor correction (PFC) stage, compressor motor drive, and fan motor drive. A sensorless Field-Oriented Control (FOC)-based Permanent Magnet Synchronous Motor (PMSM) drive is used in the ODU compressor and fan motors to control motor speed and torque by varying the input frequency and voltage of the motors. PFC ensures that the current waveform follows the voltage waveform, improving the line-side power factor, and regulates the output DC voltage to a constant value, regardless of any changes in load or input conditions. www.ti.com TMS320F2800137, TMS320F2800135, TMS320F2800133, TMS320F2800132 SPRSP63B – OCTOBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 177 Product Folder Links: TMS320F2800137 TMS320F2800135 TMS320F2800133 TMS320F2800132

8.3.1.4 Merchant Telecom Rectifiers

Merchant telecom rectifier consists of a power factor correction (PFC) stage and a DC-DC converter stage. The Totem pole PFC is widely used as the PFC stage. For the DC-DC stage, LLC and phase-shifted full bridge (PSFB) are the two most popular topologies. Single-chip and two-chip architecture can be used in merchant telecom rectifier, as shown in Figure 8-9 and Figure 8-10. The PFC stage draws sine-wave current from the AC mains in phase with the AC voltage, and maintains a steady DC bus voltage (VDC, typically +400 V) across its output. This output voltage is applied to the input of DC-DC stage, which converts it to an isolated low-output voltage Vout (usually 48 V).

9 Device and Documentation Support

TI offers an extensive line of development tools. Tools and software to evaluate the performance of the device, generate code, and develop solutions are listed below.

9.1 Getting Started and Next Steps

The Getting Started With C2000 ™ Real-Time Control Microcontrollers (MCUs) Getting Started Guide covers all aspects of development with C2000 devices from hardware to support resources. In addition to key reference documents, each section provides relevant links and resources to further expand on the information covered.

9.2 Device Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (for example, TMS320F2800137). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX and TMDX) through fully qualified production devices and tools (TMS and TMDS). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow. TMP Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications. TMS Production version of the silicon die that is fully qualified. Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully-qualified development-support product. TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." Production devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (X or P) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, PM). For orderable part numbers of TMS320F280013x devices in the PM, PT, RGZ, and RHB package types, see the Package Option Addendum of this document, ti.com, or contact your TI sales representative.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width.
