3 Description

The AM68 scalable processor family is based on the evolutionary Jacinto™ 7 architecture, targeted at Smart Vision Camera and General Compute applications and built on extensive market knowledge accumulated over a decade of TI’s leadership in the Vision processor market. The AM68x family is built for a broad set of cost-sensitive high-performance compute applications in Factory Automation, Building Automation, and other markets. The AM68 provides high performance compute technology for both traditional and deep learning algorithms at industry leading power/performance ratios with a high level of system integration to enable scalability and lower costs for advanced vision camera applications. Key cores include the latest Arm and GPU processors for general compute, next generation DSP with scalar and vector cores, dedicated deep learning and traditional algorithm accelerators, an integrated next generation imaging subsystem (ISP), video codec, and isolated MCU island. All protected by industrial-grade safety and security hardware accelerators. General Compute Cores and Integration Overview: Separate dual core cluster configuration of Arm ® Cortex®-A72 facilitates multi-OS applications with minimal need for a software hypervisor. Up to two Arm ® Cortex®-R5F subsystems enable low-level, timing critical processing tasks to leave the Arm ® Cortex®-A72 core’s unencumbered for applications. Building on the existing world-class ISP, TI’s 7th generation ISP includes flexibility to process a broader sensor suite, support for higher bit depth, and features targeting analytics applications. Integrated diagnostics and safety features support operations up to SIL-2 levels while the integrated security features protect data against modern day attacks. CSI2.0 ports enable multi sensor inputs. Key Performance Cores Overview: The C7000™ DSP next generation core (“C7x”) combines TI’s industry leading DSP and EVE cores into a single higher performance core and adds floating-point vector calculation capabilities, enabling backward compatibility for legacy code while simplifying software programming. The new “MMA” deep learning accelerator enables performance up to 8 Trillion Operations Per Second (TOPS) within the lowest power envelope in the industry even when operating even at the worst case junction temperatures of 105°C and 125°C. The dedicated Vision hardware accelerators provide vision pre-processing with no impact on system performance. The C7x/MMA cores are available only for deep learning function in the AM68 class of processors. AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 www.ti.com

over operating free-air temperature range (unless otherwise noted) (1) (2) PARAMETER MIN MAX UNIT TSTG (5) Storage temperature –55 +150 °C (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime. (2) All voltage values are with respect to their associated VSS or VSSA_x, unless otherwise noted. (3) This parameter applies to all IO pins which are not fail-safe and the requirement applies to all values of IO supply voltage. For example, if the voltage applied to a specific IO supply is 0 volts the valid input voltage range for any IO powered by that supply will be –0.3 to +0.3 volts. Special attention should be applied anytime peripheral devices are not powered from the same power sources used to power the respective IO supply. It is important the attached peripheral never sources a voltage outside the valid input voltage range, including power supply ramp-up and ramp-down sequences. (4) For current pulse injection: Pins stressed per JEDEC JESD78E (Class II) and passed with specified I/O pin injection current and clamp voltage of 1.5 times maximum recommended I/O voltage and negative 0.5 times maximum recommended I/O voltage. For overvoltage performance: Supplies stressed per JEDEC JESD78E (Class II) and passed specified voltage injection. (5) For tape and reel the storage temperature range is [–10°C; +50°C] with a maximum relative humidity of 70%. TI recommends returning to ambient room temperature before usage. (6) VDD is the voltage on the corresponding power-supply pin(s) for the IO. (7) The VMON pins provides a way to monitor the system power supply. For more information, see System Power Supply Monitor Design Guidelines using VMON/POK. (8) An external resistor divider is required to limit the voltage applied to this device pin. For more information, see USB VBUS Design Guidelines. Fail-safe IO terminals are designed such they do not have dependencies on the respective IO power supply voltage. This allows external voltage sources to be connected to these IO terminals when the respective IO power supplies are turned off. The specific signals that are fail safe are highlighted in the parameter "Steady State Max. Voltage at all fail-safe IO pins". All other IO terminals are not fail-safe and the voltage applied to them should be limited to the value defined by the "Steady State Max. Voltage at all other IO pins" parameter in Absolute Maximum Ratings. Tovershoot Tundershoot Tperiod Overshoot = 20% of nominal IO supply voltage Undershoot = 20% of nominal IO supply voltage A. Tovershoot + Tundershoot < 20% of Tperiod Figure 7-1. IO Transient Voltage Ranges

This requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, and so forth. This is required for all supply inputs, but special care should be given to the VDD_CORE, VDD_MCU, and VDD_CPU domains which have higher transient current demand compared to other rails. (2) Refer to Power-On-Hour (POH) Limits for limitations. (3) VDDS_DDR is required to still be powered with LPDDR4 voltage ranges, even If DDR interface is unused. (4) This terminal is connected to analog circuits in the respective USB PHY. The circuit sources a known current while measuring the voltage to determine if the terminal is connected to VSS with a resistance less than 10 Ω or greater than 100 kΩ. The terminal should be connected to ground for USB host operation or open-circuit for USB peripheral operation, and should never be connected to any external voltage source. (5) The AVS Voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be read from the VTM_DEVINFO_VDn. For information about VTM_DEVINFO_VDn Registers address, please refer to Voltage and Thermal Manager section in the device TRM. The power supply should be adjustable over the ranges shown in the VDD_CPU AVS Range entry. (6) When DDR1 is used concurrently with either OSPI0 or Hyperbus, VDDSHV1_MCU is limited to 1.8V (3.3V mode not supported if DDR1 is used in the system.) (7) An external resistor divider is required to limit the voltage applied to this device pin. For more information, see USB VBUS Design Guidelines.

7.10.2 Power Supply Sequencing

This section describes power supply sequencing required to ensure proper device operation. The device can be operated using either an isolated or combined MCU & Main power distribution network (PDN). Two different primary power sequences are recommended based upon isolated and combined MCU & Main PDNs. In addition, the device can be operated in either MCU Only or DDR Retention or GPIO Retentioon low power modes. Two different desired device power supply sequences for entry and exit of low power modes are shown. The power supply names used in this section are specific to this device and align to names given in the Signal Descriptions section. Common power supply names may be used across different devices within the Jacinto 7 TM processor family. These common supply names will have very similar if not identical functions across devices. All power sequencing timing diagrams shown will use the following terminology:

• Primary = Essential power sequences of all voltage domains between off and full active states.
• VOPR MIN = Minimum operational voltage level that ensures functionality as specified in Recommended Operating Conditions

7.10.2.1 Power Supply Slew Rate Requirement

To maintain the safe operating range of the internal ESD protection devices, TI recommends limiting the maximum slew rate of supplies to be less than 100 mV/us, as shown in Figure 7-2. For instance, a 1.8V supply should have a ramp time > 18 μs to ensure the slew rate < 100mV/us. Figure 7-2 describes the Power Supply Slew Rate Requirement in the device. t Supply value SPRSP08_ELCH_06 Slew Rate = ∆V / ∆T Max Slew Rate < 100 mV / µs or 0.1 V / 1E(-6)s = 1E(+5) V / s ∆Tmin > ∆V / Max Slew Rate or 1.8 V / 1E(+5) V / s ∆Tmin > 18 µs Figure 7-2.

7.10.2.4 Isolated MCU and Main Domains Power- Up Sequencing

Isolated MCU and Main voltage domains enable an SoC’s MCU and Main processor sub-systems to operate independently. There are 2 reasons an SoC’s PDN design may need to support independent MCU and Main processor functionality. First is to provide flexibility to enable SoC low power modes that can significant reduce SoC power dissipation when processor operations are not needed. Second is to enable robustness to gain freedom from interference (FFI) of a single fault impacting both MCU and Main processor sub-systems which is especially beneficial if using the SoC’s MCU as the system safety monitoring processor. The number of additional PDN power rails needed is dependent upon number of different MCU IO signaling voltage levels. If only 1.8V IO signaling is used, then only 2 additional power rails could be required. If both 1.8 and 3.3V IO signaling is desired, then 4 additional power rails could be needed.

7.10.4 Clock Specifications

7.10.4.1 Input and Output Clocks / Oscillators

Various external clock inputs/outputs are needed to drive the device. Summary of these input clock signals is as follows:

• High frequency oscillators inputs – OSC1_XO/OSC1_XI — external main crystal interface pins connected to internal oscillator which sources reference clock. Provides reference clock to PLLs within MCU domain and MAIN domain. This high- frequency oscillator is used to provide audio clock frequencies to MCASPs. – WKUP_OSC0_XO/WKUP_OSC0_XI — external main crystal interface pins connected to internal oscillator which sources reference clock. Provides reference clock to PLLs within WKUP and MAIN domain.
• Low frequency digital input – WKUP_LF_CLKIN - Low Frequency 32k digital clock input, optionally sourced from an external PMIC or other clock source. This SoC does not support a LFOSC crystal input.
• General purpose clock inputs – MCU_EXT_REFCLK0 - optional external System clock input (MCU domain). – EXT_REFCLK1 — optional external System clock input (MAIN domain).
• Peripheral clocks - refer to the Signal Descriptions for peripheral specific clocks For more information about Input clock interfaces, see Clocking section in Device Configuration chapter in the device TRM.

WKUP_OSC0 Start-up Time The crystal circuit must be designed such that it applies the appropriate capacitive load to the crystal, as defined by the crystal manufacturer. The capacitive load, C L, of this circuit is a combination of discrete capacitors CL1, C L2, and several parasitic contributions. PCB signal traces which connect crystal circuit components to WKUP_OSC0_XI and WKUP_OSC0_XO have parasitic capacitance to ground, C PCBXI and C PCBXO, where the PCB designer should be able to extract parasitic capacitance for each signal trace. The WKUP_OSC0 circuits and device package have combined parasitic capacitance to ground, C PCBXI and CPCBXO, where these parasitic capacitance values are defined in Table 7-22. J7ES_WKUP_OSC_CC_05 CPCBXI CPCBXO CL1 CL2 PCB Signal Traces Crystal Circuit Components WKUP_OSC0_XO WKUP_OSC0_XI CXI CXO Device Figure 7-25. Load Capacitance Load capacitors, C L1 and C L2 in Figure 7-23, should be chosen such that the below equation is satisfied. C L in the equation is the load specified by the crystal manufacturer. CL = [(CL1 + CPCBXI + CXI) × (CL2 + CPCBXO + CXO)] / [(CL1 + CPCBXI + CXI) + (CL2 + CPCBXO + CXO)] To determine the value of CL1 and CL2, multiply the capacitive load value C L by 2. Using this result, subtract the combined values of C PCBXI + C XI to determine the value of C L1 and the combined values of C PCBXO + C XO to determine the value of C L2. For example, if C L = 10 pF, C PCBXI = 2.9 pF, C XI = 0.5 pF, C PCBXO = 3.7 pF, C XO = 0.5 pF, the value of CL1 = [(2CL) - (CPCBXI + CXI)] = [(2 × 10 pF) - 2.9 pF - 0.5 pF)] = 16.6 pF and C L2 = [(2CL) - (CPCBXO + CXO)] = [(2 × 10 pF) - 3.7 pF - 0.5 pF)] = 15.8 pF AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 www.ti.com

The crystal circuit must also be designed such that it does not exceed the maximum shunt capacitance for WKUP_OSC0 operating conditions defined in Table 7-21. Shunt capacitance, C shunt, of the crystal circuit is a combination of crystal shunt capacitance and parasitic contributions. PCB signal traces which connect crystal circuit components to WKUP_OSC0 have mutual parasitic capacitance to each other, C PCBXIXO, where the PCB designer should be able to extract mutual parasitic capacitance between these signal traces. The device package also has mutual parasitic capacitance, C XIXO, where this mutual parasitic capacitance value is defined in Table 7-22. PCB routing should be designed to minimize mutual capacitance between XI and XO signal traces. This is typically done by keeping signal traces short and not routing them in close proximity. Mutual capacitance can also be minimized by placing a ground trace between these signals when the layout requires them to be routed in close proximity. It is important to minimize the mutual capacitance on the PCB to provide as much margin as possible when selecting a crystal. J7ES_WKUP_OSC_SC_06 Device WKUP_OSC0_XO WKUP_OSC0_XI CPCBXIXO PCB Signal Traces Crystal Circuit Components CXIXOCO Figure 7-26. Shunt Capacitance A crystal should be chosen such that the below equation is satisfied. C O in the equation is the maximum shunt capacitance specified by the crystal manufacturer. Cshunt ≥ CO + CPCBXIXO + CXIXO For example, the equation would be satisfied when the crystal being used is 25 MHz with an ESR = 30 Ω, CPCBXIXO = 0.04 pF, CXIXO = 0.01 pF, and shunt capacitance of the crystal is less than or equal to 6.95 pF.

7.10.4.1.2 WKUP_OSC0 LVCMOS Digital Clock Source

Figure 7-27 shows the recommended oscillator connections when WKUP_OSC0_XI is connected to a 1.8-V LVCMOS square-wave digital clock source. Note A DC steady-state condition is not allowed on WKUP_OSC0_XI when the oscillator is powered up.

OSC1 Start-up Time The crystal circuit must be designed such that it applies the appropriate capacitive load to the crystal, as defined by the crystal manufacturer. The capacitive load, C L, of this circuit is a combination of discrete capacitors C L1, CL2, and several parasitic contributions. PCB signal traces which connect crystal circuit components to OSC1_XI and OSC1_XO have parasitic capacitance to ground, C PCBXI and C PCBXO, where the PCB designer should be able to extract parasitic capacitance for each signal trace. The OSC1 circuits and device package have combined parasitic capacitance to ground, C PCBXI and C PCBXO, where these parasitic capacitance values are defined in Table 7-24.

Load Capacitance Load capacitors, C L1 and C L2 in Figure 7-28, should be chosen such that the below equation is satisfied. C L in the equation is the load specified by the crystal manufacturer. CL = [(CL1 + CPCBXI + CXI) × (CL2 + CPCBXO + CXO)] / [(CL1 + CPCBXI + CXI) + (CL2 + CPCBXO + CXO)] To determine the value of CL1 and CL2, multiply the capacitive load value C L by 2. Using this result, subtract the combined values of C PCBXI + C XI to determine the value of C L1 and the combined values of C PCBXO + C XO to determine the value of C L2. For example, if C L = 10 pF, C PCBXI = 2.9 pF, C XI = 0.5 pF, C PCBXO = 3.7 pF, C XO = 0.5 pF, the value of CL1 = [(2CL) - (CPCBXI + CXI)] = [(2 × 10 pF) - 2.9 pF - 0.5 pF)] = 16.6 pF and C L2 = [(2CL) - (CPCBXO + CXO)] = [(2 × 10 pF) - 3.7 pF - 0.5 pF)] = 15.8 pF AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 www.ti.com

The crystal circuit must also be designed such that it does not exceed the maximum shunt capacitance for OSC1 operating conditions defined in Table 7-23 . Shunt capacitance, C shunt, of the crystal circuit is a combination of crystal shunt capacitance and parasitic contributions. PCB signal traces which connect crystal circuit components to OSC1 have mutual parasitic capacitance to each other, CPCBXIXO, where the PCB designer should be able to extract mutual parasitic capacitance between these signal traces. The device package also has mutual parasitic capacitance, CXIXO, where this mutual parasitic capacitance value is defined in Table 7-24. PCB routing should be designed to minimize mutual capacitance between XI and XO signal traces. This is typically done by keeping signal traces short and not routing them in close proximity. Mutual capacitance can also be minimized by placing a ground trace between these signals when the layout requires them to be routed in close proximity. It is important to minimize the mutual capacitance on the PCB to provide as much margin as possible when selecting a crystal.

Shunt Capacitance A crystal should be chosen such that the below equation is satisfied. C O in the equation is the maximum shunt capacitance specified by the crystal manufacturer. Cshunt ≥ CO + CPCBXIXO + CXIXO For example, the equation would be satisfied when the crystal being used is 25 MHz with an ESR = 30 Ω, CPCBXIXO = 0.04 pF, CXIXO = 0.01 pF, and shunt capacitance of the crystal is less than or equal to 6.95 pF.

7.10.5.12 I2C

The device contains several multicontroller Inter-Integrated Circuit (I2C) controllers. Each I2C controller was designed to be compliant to the Philips I2C-bus ™ specification version 2.1. However, the device IO Buffers are not fully compliant to the I2C electrical specification. Some I2C instances use the LVCMOS Buffer Type, while other instances use the I2S OD FS Buffer type. See the Pin Attributes table to determine the IO Buffer Type used for each I2C instance on this device. The I2C speeds supported and exceptions are described per IO Buffer Type below:

• I2C instances that use the LVCMOS buffer type – Speeds:
• Standard-mode (up to 100 Kbits/s) – 1.8 V – 3.3 V
• Fast-mode (up to 400 Kbits/s) – 1.8 V – 3.3 V – Exceptions:
• The IOs associated with these ports are not compliant to the fall time requirements defined in the I2C specification because they are implemented with higher performance LVCMOS push-pull IOs that were designed to support other signal functions that could not be implemented with I2C compatible IOs. The LVCMOS IOs being used on these ports are connected such they emulate open-drain outputs. This emulation is achieved by forcing a constant low output and disabling the output buffer to enter the Hi-Z state.
• The I2C specification defines a maximum input voltage VIH of (VDDmax + 0.5 V), which exceeds the absolute maximum ratings for the device IOs. The system must be designed to ensure the I2C signals never exceed the limits defined in the Absolute Maximum Ratings section of this data sheet.
• I2C instances that use the I2C OD FS buffer type – Speeds:
• Standard-mode (up to 100 Kbits/s) – 1.8 V – 3.3 V
• Fast-mode (up to 400 Kbits/s) – 1.8 V – 3.3 V
• Hs-mode (up to 3.4 Mbit/s) – 1.8 V – Exceptions:
• The IOs associated with these ports were not design to support Hs-mode while operating at 3.3 V. So Hs-mode is limited to 1.8-V operation.
• The rise and fall times of the I2C signals connected to these ports must not exceed a slew rate of 0.8 V/ns (or 8E+7 V/s). This limit is more restrictive than the minimum fall time limits defined in the I2C specification. Therefore, it may be necessary to add additional capacitance to the I2C signals to slow the rise and fall times such that they do not exceed a slew rate of 0.8 V/ns. www.ti.com AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 191 Product Folder Links: AM68A AM68

UART Timing Conditions PARAMETER DESCRIPTION MIN MAX UNIT INPUT CONDITIONS SRI Input slew rate 0.5 5 V/ns OUTPUT CONDITIONS CL Output load capacitance 1 30(1) pF (1) This value represents an absolute maximum load capacitance. As the UART baud rate increases, it may be necessary to reduce the load capacitance to a value less than this maximum limit to provide enough timing margin for the attached device. The output rise/fall times increase as capacitive load increases, which decreases the time data is valid for the receiver of the attached devices. Therefore, it is important to understand the minimum data valid time required by the attached device at the operating baud rate. Then use the device IBIS models to verify the actual load capacitance on the UART signals does not increase the rise/fall times beyond the point where the minimum data valid time of the attached device is violated. characteristics for UART interface.

The JTAG signals are split across two IO power domains on the device. Timings parameters defined in this section only apply when the two IO power domains are operating at the same voltage and level- shifters are not inserted into the signal path. Values for the following timing parameters are not defined when operating the two IO power domains at different voltages since propagation delay through the device IO buffers differ when some are operating at 1.8 V while others are operating at 3.3 V. This effectively reduces timing margin beyond the values defined in this section. The JTAG interface is still expected to function when the two IO power domains are operated at different voltages, assuming the system designer has implemented appropriate level-shifters and the operating frequency is reduced to accommodate additional delay inserted by the level-shifters and IO buffers operating at different voltages.

9.2.3 USB VBUS Design Guidelines

The USB 3.1 specification allows the VBUS voltage to be as high as 5.5 V for normal operation, and as high as 20 V when the Power Delivery addendum is supported. Some automotive applications require a max voltage to be 30 V. The device requires the VBUS signal voltage be scaled down using an external resistor divider (as shown in the Figure 9-4), which limits the voltage applied to the actual device pin (USB0_VBUS). The tolerance of these external resistors should be equal to or less than 1%, and the leakage current of zener diode at 5 V should be less than 100 nA.(1) www.ti.com AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 237 Product Folder Links: AM68A AM68

USB VBUS Detect Voltage Divider / Clamp Circuit The USB0_VBUS pin can be considered to be fail-safe because the external circuit in Figure 9-4 limits the input current to the actual device pin in a case where VBUS is applied while the device is powered off.

9.2.4 System Power Supply Monitor Design Guidelines using VMON/POK

The VMON1_ER_VSYS pin provides a way to monitor a system power supply. This system power supply is typically a single pre-regulated power source for the entire system. This supply is monitored by comparing the output of an external voltage divider circuit sourced by this supply with an internal voltage reference, with a power fail event being triggered when the voltage applied to VMON1_ER_VSYS drops below the internal reference voltage. The actual system power supply voltage trip point is determined by the system designer when selecting component values used to implement the external resistor voltage divider circuit. When designing the resistor divider circuit it is important to understand various factors which contribute to variability in the system power supply monitor trip point. The first thing to consider is the initial accuracy of the VMON1_ER_VSYS input threshold which has a nominal value of 0.45 V, with a variation of ±3%. Precision 1% resistors with similar thermal coefficient are recommended for implementing the resistor voltage divider. This minimizes variability contributed by resistor value tolerances. Input leakage current associated with VMON1_ER_VSYS must also be considered since any current flowing into the pin creates a loading error on the voltage divider output. The VMON1_ER_VSYS input leakage current may be in the range of 10 nA to 2.5 μA when applying 0.45 V. Note The resistor voltage divider shall be designed such that its output voltage never exceeds the maximum value defined in Recommended Operating Conditions during normal operating conditions. Figure 9-5 presents an example, where the system power supply is nominally 5 V and the maximum trigger threshold is 5 V - 10%, or 4.5 V. For this example, it is important to understand which variables effect the maximum trigger threshold when selecting resistor values. It is obvious a device which has a VMON1_ER_VSYS input threshold of 0.45 V + 3% needs to be considered when trying to design a voltage divider that doesn’t trip until the system supply drops 10%. The effect of resistor tolerance and input leakage also needs to be considered, but how these contributions effect the maximum trigger point may not be obvious. When selecting component values which produce a maximum trigger voltage, the system designer must consider a condition where the value of R1 is 1% low and the value of R2 is 1% high combined with a condition where input leakage current for the VMON1_ER_VSYS pin is 2.5 μA. When implementing a resistor divider where R1 = 4.81 KΩ and R2 = 40.2 KΩ, the result is a maximum trigger threshold of 4.523 V. Once component values have been selected to satisfy the maximum trigger voltage as described above, the system designer can determine the minimum trigger voltage by calculating the applied voltage that produces an output voltage of 0.45 V - 3% when the value of R1 is 1% high and the value of R2 is 1% low, and the input AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 www.ti.com

leakage current is 10 nA, or zero. Using an input leakage of zero with the resistor values given above, the result is a minimum trigger threshold of 4.008 V. This example demonstrates a system power supply voltage trip point that ranges from 4.008 V to 4.523 V. Approximately 250 mV of this range is introduced by VMON1_ER_VSYS input threshold accuracy of ±3%, approximately 150 mV of this range is introduced by resistor tolerance of ±1%, and approximately 100 mV of this range is introduced by loading error when VMON1_ER_VSYS input leakage current is 2.5 μA. The resistor values selected in this example produces approximately 100 μA of bias current through the resistor divider when the system supply is 4.5 V. The 100 mV of loading error mentioned above could be reduced to about 10 mV by increasing the bias current through the resistor divider to approximately 1 mA. So resistor divider bias current vs loading error is something the system designer needs to consider when selecting component values. The system designer should also consider implementing a noise filter on the voltage divider output since VMON1_ER_VSYS has minimum hysteresis and a high-bandwidth response to transients. This could be done by installing a capacitor across R1 as shown in Figure 9-5. However, the system designer must determine the response time of this filter based on system supply noise and expected response to transient events. Figure 9-5 presents an example, when the system power supply voltage is nominally 5 V and the desired trigger threshold is -10% or 4.5 V.

System Supply Monitor Voltage Divider Circuit The VMON2_IR_VCPU pin provides a way to monitor VDD_CPU power supply. Must be externally connected as close as possible to VDD_CPU pin on the board. SoCs that have a VMON6_IR_VEXT0P8 can optionally monitor other domains such as VDD_CORE or VDD_MCU. Similarly, those signals should be as close as possible to VDD_CORE or VDD_MCU pin on the board. The VMON3_IR_VEXT1P8 and VMON4_IR_VEXT1P8 pins provide a way to monitor an external 1.8-V power supply. The VMON5_IR_VEXT3P3 pin provides a way to monitor an external 3.3-V power supply. An internal resistor divider with software control is implemented inside the SoC. Software can program the internal resistor divider to create appropriate under voltage and over voltage interrupts. These pins should not be sourced from an external resistor divider. If the monitored voltage requires adjustment, be sure to buffer the divided voltage prior connecting to monitor pin.

10 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.

10.1 Device Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix). 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 (TMDX) through fully qualified production devices and tools (TMDS). Device development evolutionary flow: X Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow. P Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications. null 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. X and P 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. For orderable part numbers, see the Package Option Addendum of this document, the TI website ( ti.com), or contact your TI sales representative. www.ti.com AM68A, AM68 SPRSP91A – FEBRUARY 2023 – REVISED AUGUST 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 241 Product Folder Links: AM68A AM68
