4.2 Pin Attributes and Pin Multiplexing
The device makes extensive use of pin multiplexing to accommodate the large number of peripheral functions in the smallest possible package. To achieve this configuration, pin multiplexing is controlled using a combination of hardware configuration (at device reset) and register control. NOTE TI highly recommends using Pin Mux Tool to obtain the desired pinout. The board and software designers are responsible for the proper pin multiplexing configuration. Hardware does not ensure that the proper pin multiplexing options are selected for the peripherals or interface mode used. Table 4-1 and Table 4-2 list the pin descriptions and attributes. Table 4-3 lists the signal descriptions. Table 4-4 presents an overall view of pin multiplexing. All pin multiplexing options are configurable using the pin mux registers. The following special considerations apply:
- All I/Os support drive strengths of 2, 4, and 6 mA. The drive strength is individually configurable for each pin.
- All I/Os support 10-µA pullup and pulldown resistors.
- The VIO and VBAT supply must be tied together at all times.
- By default, all I/Os float in the Hibernate state. However, the default state can be changed by SW.
- All digital I/Os are nonfail-safe. NOTE If an external device drives a positive voltage to the signal pads and the CC3220x device is not powered, DC is drawn from the other device. If the drive strength of the external device is adequate, an unintentional wakeup and boot of the CC3220x device can occur. To prevent current draw, TI recommends any one of the following conditions:
- All devices interfaced to the CC3220x device must be powered from the same power rail as the chip.
- Use level shifters between the device and any external devices fed from other independent rails.
- The nRESET pin of the CC3220x device must be held low until the VBAT supply to the device is driven and stable.
- All GPIO pins default to high impedance unless programmed by the MCU. The bootloader sets the TDI, TDO, TCK, TMS, and Flash_SPI pins to mode 1. All the other pins are left in the Hi-Z state.

NAME (1) This pin has dual functions: as a SOP[2] (device operation mode), and as an external TCXO enable. As a TXCO enable, the pin is an output on power up and driven logic high. During hibernate low-power mode, the pin is in a Hi-Z state but is pulled down for SOP mode to disable TCXO. Because of the SOP functionality, the pin must be used as an output only. (2) This pin is reserved for WLAN antenna selection, controlling an external RF switch that multiplexes the RF pin of the CC3220x device between two antennas. These pins must not be used for other functionalities. (3) Device firmware automatically enables the digital path during ROM boot.

Pin Descriptions (continued) PINS TYPE DESCRIPTION SELECT AS WAKEUP SOURCE CONFIGURE ADDITIONAL ANALOG MUX MUXED WITH JTAGNO. NAME (4) Pin 45 is used by an internal DC/DC converter (ANA2_DCDC). This pin will be available automatically if the serial flash is forced in the CC3220SF device. For the CC3220R and CC3220S devices, pin 45 can be used as GPIO_31 if a supply is provided on pin 47. (5) Pin 52 is used by the RTC crystal oscillator. These devices use automatic configuration sensing. Therefore, some board-level configuration is required to use pin 52 as a digital pad. Pin 52 is used for the RTC crystal in most applications. However, in some applications a 32.768-kHz square-wave clock might always be available onboard. When a 32.768-kHz square-wave clock is available, the crystal can be removed to free pin 52 for digital functions. The external clock must then be applied at pin 51. For the device to automatically detect this configuration, a 100-kΩ pullup resistor must be connected between pin 52 and the supply line. To prevent false detection, TI recommends using pin 52 for output-only functions. (6) To use the digital functions, RTC_XTAL_N must be pulled high to the supply voltage using a 100-kΩ resistor. (7) This pin is shared by the ADC inputs and digital I/O pad cells. (8) Requires user configuration to enable the analog switch of the ADC channel (the switch is off by default.) The digital I/O is always connected and must be made Hi-Z before enabling the ADC switch.

This pin will be available automatically if serial flash is forced in the CC3220SF device. For the CC3220R and CC3220S devices, pin 45 can be used as GPIO_31 if a supply is provided on pin 47. (11) Pin 52 is used by the RTC crystal oscillator. These devices use automatic configuration sensing. Therefore, some board-level configuration is required to use pin 52 as a digital pad. Pin 52 is used for RTC crystal in most applications. However, in some applications a 32.768-kHz square-wave clock might always be available onboard. When a 32.768-kHz square-wave clock is available, the crystal can be removed to free pin 52 for digital functions. The external clock must then be applied at pin 51. For the chip to automatically detect this configuration, a 100-kΩ pullup resistor must be connected between pin 52 and the supply line. To prevent false detection, TI recommends using pin 52 for output-only functions. 45(10) GPIO31 I/O UART0_RX 9 I McAFSX 12 O UART1_RX 2 I McAXR0 6 I/O GSPI_CLK 7 I/O DCDC_ANA2_SW_P (PN) — N/A (see (7)) N/A N/A N/A N/A

On the other hand, the digital pads can tolerate up to 3.6 V. Hence, take care to prevent accidental damage to the ADC inputs. TI recommends first disabling the output buffers of the digital I/Os corresponding to the desired ADC channel (that is, converted to Hi-Z state), and thereafter disabling the respective pass switches (S7 [Pin 57], S8 [Pin 58], S9 [Pin 59], and S10 [Pin 60]).

4.6 Pad State After Application of Power to Chip But Before Reset Release
When a stable power is applied to the CC3220x chip for the first time or when supply voltage is restored to the proper value following a period with supply voltage less than 1.5 V, the level of each digital pad is undefined in the period starting from the release of nRESET and until DIG_DCDC powers up. This period is less than approximately 10 ms. During this period, pads can be internally pulled weakly in either direction. If a certain set of pins is required to have a definite value during this prereset period, an appropriate pullup or pulldown resistor must be used at the board level. The recommended value of this external pull is 2.7 kΩ.

5.8 Brownout and Blackout Conditions
The device enters a brownout condition when the input voltage drops below Vbrownout (see Figure 5-4 and Figure 5-5). This condition must be considered during design of the power supply routing, especially when operating from a battery. High-current operations, such as a TX packet or any external activity (not necessarily related directly to networking) can cause a drop in the supply voltage, potentially triggering a brownout condition. The resistance includes the internal resistance of the battery, the contact resistance of the battery holder (four contacts for 2× AA batteries), and the wiring and PCB routing resistance. NOTE When the device is in HIBERNATE state, brownout is not detected. Only blackout is in effect during HIBERNATE state. Figure 5-4. Brownout and Blackout Levels (1 of 2) Figure 5-5. Brownout and Blackout Levels (2 of 2)

The current in this state can reach approximately 400 µA. The blackout condition is equivalent to a hardware reset event in which all states within the device are lost.

Brownout and Blackout Voltage Levels CONDITION VOLTAGE LEVEL UNIT Vbrownout 2.1 V Vblackout 1.67 V (1) TI recommends using the lowest possible drive strength that is adequate for the applications.

For proper operation of the CC3220x device, perform the recommended power-up sequencing as follows: 1. Tie VBAT (pins 37, 39, 44) and VIO (pins 54 and 10) together on the board. 2. Hold the RESET pin low while the supplies are ramping up. TI recommends using a simple RC circuit 3. For an external RTC, ensure that the clock is stable before RESET is deasserted (high).

5.15.2 Device Reset
When a device restart is required, the user may issue a negative pulse to the nRESET pin. The user must follow one of the two alternatives to ensure the reset is properly applied:
- A negative reset pulse (on pin 32) of at least 200-ms duration
- If the above cannot be guaranteed, a pull-down resistor of 2 MΩ should be connected to pin 52 (RTC_XTAL_N). If implemented, a shorter pulse of at least 100 µs can be used. To ensure a proper reset sequence, the user has to call the sl_stop function prior to toggling the reset. It is preferable to use software reset instead of an external trigger when a reset is required.

5.15.5 Clock Specifications
The CC3220x device requires two separate clocks for its operation:
- A slow clock running at 32.768 kHz is used for the RTC.
- A fast clock running at 40 MHz is used by the device for the internal processor and the WLAN subsystem. The device features internal oscillators that enable the use of less-expensive crystals rather than dedicated TCXOs for these clocks. The RTC can also be fed externally to provide reuse of an existing clock on the system and to reduce overall cost.
5.15.5.1 Slow Clock Using Internal Oscillator
The RTC crystal connected on the device supplies the free-running slow clock. The accuracy of the slow clock frequency must be 32.768 kHz ±150 ppm. In this mode of operation, the crystal is tied between RTC_XTAL_P (pin 51) and RTC_XTAL_N (pin 52) with a suitable load capacitance to meet the ppm requirement.

The crystal is fed directly between WLAN_XTAL_P (pin 23) and WLAN_XTAL_N (pin 22) with suitable loading capacitors. Figure 5-11 shows the crystal connections for the fast clock. NOTE: The crystal capacitance must be tuned to ensure that the PPM requirement is met. See CC31xx & CC32xx Frequency Tuning for information on frequency tuning. Figure 5-11.

5.15.5.4 Fast Clock (Fref) Using an External Oscillator
The CC3220x device can accept an external TCXO/XO for the 40-MHz clock. In this mode of operation, the clock is connected to WLAN_XTAL_P (pin 23). WLAN_XTAL_N (pin 22) is connected to GND. The external TCXO/XO can be enabled by TCXO_EN (pin 21) from the device to optimize the power consumption of the system. If the TCXO does not have an enable input, an external LDO with an enable function can be used. Using the LDO improves noise on the TCXO power supply. Figure 5-12 shows the connection. Figure 5-12.

5.15.6.9 SD Host
CC3220x provides an interface between a local host (LH), such as an MCU and an SD memory card, and handles SD transactions with minimal LH intervention. The SD host does the following:
- Provides SD card access in 1-bit mode
- Deals with SD protocol at the transmission level
- Handles data packing
- Adds cyclic redundancy checks (CRC)
- Start and end bit
- Checks for syntactical correctness The application interface sends every SD command and either polls for the status of the adapter or waits for an interrupt request. The result is then sent back to the application interface in case of exceptions or to warn of end-of-operation. The controller can be configured to generate DMA requests and work with minimum CPU intervention. Given the nature of integration of this peripheral on the CC3220x platform, TI recommends that developers use peripheral library APIs to control and operate the block. This section emphasizes understanding the SD host APIs provided in the peripheral library of the CC3220x Software Development Kit (SDK). The SD Host features are as follows:
- Full compliance with SD command and response sets, as defined in the SD memory card – Specifications, v2.0 – Includes high-capacity (size >2 GB) cards HC SD

6.4 Power-Management Subsystem
The CC3220x power-management subsystem contains DC/DC converters to accommodate the different voltage or current requirements of the system.
- Digital DC/DC (Pin 44) – Input: VBAT wide voltage (2.1 to 3.6 V) or preregulated 1.85 V
- ANA1 DC/DC (Pin 37) – Input: VBAT wide voltage (2.1 to 3.6 V) – In preregulated 1.85-V mode, the ANA1 DC/DC converter is bypassed.
- PA DC/DC (Pin 39) – Input: VBAT wide voltage (2.1 to 3.6 V) – In preregulated 1.85-V mode, the PA DC/DC converter is bypassed.
- ANA2 DC/DC (Pin 47) – Input: VBAT wide voltage (2.1 to 3.6 V) or preregulated 1.85 V The CC3220x device is a single-chip WLAN radio solution used on an embedded system with a wide- voltage supply range. The internal power management, including DC/DC converters and LDOs, generates all of the voltages required for the device to operate from a wide variety of input sources. For maximum
6.4.1 VBAT Wide-Voltage Connection
In the wide-voltage battery connection, the device is powered directly by the battery or preregulated 3.3-V supply. All other voltages required to operate the device are generated internally by the DC/DC converters. This scheme supports wide-voltage operation from 2.1 to 3.6 V and is thus the most common mode for the device.

The VBAT and the VIO are also connected to the 1.85-V supply. This mode provides the lowest BOM count version in which inductors used for PA DC/DC and ANA1 DC/DC (2.2 and 1 µH) and a capacitor (22 µF) can be avoided. In the preregulated 1.85-V mode, the regulator providing the 1.85 V must have the following characteristics:
- Load current capacity ≥900 mA
- Line and load regulation with <2% ripple with 500-mA step current and settling time of < 4 µs with the load step NOTE The regulator must be placed as close as possible to the device so that the IR drop to the device is very low.
6.5 Low-Power Operating Mode
From a power-management perspective, the CC3220x device comprises the following two independent subsystems:
- Arm Cortex-M4 application processor subsystem
- Networking subsystem Each subsystem operates in one of several power states. The Cortex-M4 application processor runs the user application loaded from an external serial Flash, or internal Flash (in CC3220SF). The networking subsystem runs preprogrammed TCP/IP and Wi-Fi data link layer functions. The user program controls the power state of the application processor subsystem and can be in one of the five modes described in Table 6-2. Table 6-2. User Program Modes APPLICATION PROCESSOR (MCU) MODE(1) DESCRIPTION MCU active mode MCU executing code at 80-MHz state rate MCU sleep mode The MCU clocks are gated off in sleep mode and the entire state of the device is retained. Sleep mode offers instant wakeup. The MCU can be configured to wake up by an internal fast timer or by activity from any GPIO line or peripheral. MCU LPDS mode State information is lost and only certain MCU-specific register configurations are retained. The MCU can wake up from external events or by using an internal timer. (The wake-up time is less than 3 ms.) Certain parts of memory can be retained while the MCU is in LPDS mode. The amount of memory retained is configurable. Users can choose to preserve code and the MCU-specific setting. The MCU can be configured to wake up using the RTC timer or by an external event on specific GPIOs as the wake-up source. MCU hibernate mode The lowest power mode in which all digital logic is power-gated. Only a small section of the logic directly powered by the input supply is retained. The RTC keeps running and the MCU supports wakeup from an external event or from an RTC timer expiry. Wake-up time is longer than LPDS mode at about 15 ms plus the time to load the application from serial Flash, which varies according to code size. In this mode, the MCU can be configured to wake up using the RTC timer or external event on a GPIO. MCU shutdown mode The lowest power mode system-wise. All device logics are off, including the RTC. The wake-up time in this mode is longer than hibernate at about 1.1 s. To enter or exit the shutdown mode, the state of the nRESET line is changed (low to shut down, high to turn on).

When there is no network activity, the NWP sleeps most of the time and wakes up only for beacon reception (see Table 6-3). Table 6-3. Networking Subsystem Modes NETWORK PROCESSOR MODE DESCRIPTION Network active mode (processing layer 3, 2, and 1) Transmitting or receiving IP protocol packets Network active mode (processing layer 2 and 1) Transmitting or receiving MAC management frames; IP processing not required. Network active listen mode Special power optimized active mode for receiving beacon frames (no other frames supported) Network connected Idle A composite mode that implements 802.11 infrastructure power save operation. The CC3220x NWP automatically goes into LPDS mode between beacons and then wakes to active listen mode to receive a beacon and determine if there is pending traffic at the AP. If not, the NWP returns to LPDS mode and the cycle repeats. Network LPDS mode Low-power state between beacons in which the state is retained by the NWP, allowing for a rapid wake up. Network disabled The network is disabled The operation of the application and network processor ensures that the device remains in the lowest power mode most of the time to preserve battery life. The following examples show the use of the power modes in applications:
- A product that is continuously connected to the network in the 802.11 infrastructure power-save mode but sends and receives little data spends most of the time in connected idle, which is a composite of receiving a beacon frame and waiting for the next beacon.
- A product that is not continuously connected to the network but instead wakes up periodically (for example, every 10 minutes) to send data, spends most of the time in hibernate mode, jumping briefly to active mode to transmit data.

6.6 Memory
6.6.1 External Memory Requirements
The CC3220x device maintains a proprietary file system on the serial flash. The CC3220x file system stores the MCU binary, service pack file, system files, configuration files, certificate files, web page files, and user files. By using a format command through the API, users can provide the total size allocated for the file system. The starting address of the file system cannot be set and is always at the beginning of the serial flash. The applications microcontroller must access the serial flash memory area allocated to the file system directly through the CC3220x file system. The applications microcontroller must not access the serial flash memory area directly. The file system manages the allocation of serial flash blocks for stored files according to download order, which means that the location of a specific file is not fixed in all systems. Files are stored on serial flash using human-readable filenames rather than file IDs. The file system API works using plain text, and file encryption and decryption is invisible to the user. Encrypted files can be accessed only through the file system. All file types can have a maximum of 100 supported files in the file system. All files are stored in 4-KB blocks and thus use a minimum of 4KB of Flash space. Fail-safe files require twice the original size and use a minimum of 8KB. Encrypted files are counted as fail-safe in terms of space. The maximum file size is 1MB. Table 6-4 lists the minimum required memory consumption under the following assumptions:
- System files in use consume 64 blocks (256KB).
- Vendor files are not taken into account.
- MCU code is taken as the maximal possible size for the CC3220 with fail-safe enabled to account for future updates, such as through OTA.
- Gang image: – Storage for the gang image is rounded up to 32 blocks (meaning 128KB resolution). – Gang image size depends on the actual content size of all components. Additionally, the image should be 128KB aligned so unaligned memory is considered lost. Service pack, system files, and the 128KB aligned memory are assumed to occupy 256KB.
- All calculations consider that the restore-to-default is enabled. Table 6-4.

6.6.2 Internal Memory
The CC3220x device includes on-chip SRAM to which application programs are downloaded and executed. The application developer must share the SRAM for code and data. The micro direct memory access (μDMA) controller can transfer data to and from SRAM and various peripherals. The CC3220x ROM holds the rich set of peripheral drivers, which saves SRAM space. For more information on drivers, see the CC3220x API list.
6.6.2.1 SRAM
The CC3220x family provides 256KB of on-chip SRAM. Internal RAM is capable of selective retention during LPDS mode. This internal SRAM is at offset 0x2000 0000 of the device memory map. Use the µDMA controller to transfer data to and from the SRAM. When the device enters low-power mode, the application developer can choose to retain a section of memory based on need. Retaining the memory during low-power mode provides a faster wakeup. The application developer can choose the amount of memory to retain in multiples of 64KB. For more information, see the API guide.
6.6.2.2 ROM
The internal zero-wait-state ROM of the CC3220x device is at address 0x0000 0000 of the device memory and is programmed with the following components:
- Bootloader
- Peripheral driver library (DriverLib) release for product-specific peripherals and interfaces The bootloader is used as an initial program loader (when the serial Flash memory is empty). The CC3220x DriverLib software library controls on-chip peripherals with a bootloader capability. The library performs peripheral initialization and control functions, with a choice of polled or interrupt-driven peripheral support. The DriverLib APIs in ROM can be called by applications to reduce Flash memory requirements and free the Flash memory for other purposes.
6.6.2.3 Flash Memory
The CC3220SF device comes with an on-chip Flash memory of 1MB that allows application code to execute in place while freeing SRAM exclusively for read-write data. The Flash memory is used for code and constant data sections and is directly attached to the ICODE/DCODE bus of the Cortex-M4 core. A 128-bit-wide instruction prefetch buffer allows maintenance of maximum performance for linear code or loops that fit inside the buffer. The Flash memory is organized as 2-KB sectors that can be independently erased. Reads and writes can be performed at word (32-bit) level.

6.7 Restoring Factory Default Configuration
The device has an internal recovery mechanism that allows rolling back the file system to its predefined factory image or restoring the factory default parameters of the device. The factory image is kept in a separate sector on the serial flash in a secure manner and cannot be accessed from the host processor. The following restore modes are supported:
- None— no factory restore settings
- Enable restore of factory default parameters
- Enable restore of factory image and factory default parameters The restore process is performed by calling SW APIs, or by pulling or forcing SOP[2:0] = 110 pins and toggling the nRESET pin from low to high. The process is fail-safe and resumes operation if a power failure occurs before the restore is finished. The restore process typically takes about 8 seconds, depending on the attributes of the serial Flash vendor.
6.8 Boot Modes
6.8.1 Boot Mode List
The CC3220x device implements a sense-on-power (SoP) scheme to determine the device operation mode. SoP values are sensed from the device pin during power up. This encoding determines the boot flow. Before the device is taken out of reset, the SoP values are copied to a register and used to determine the device operation mode while powering up. These values determine the boot flow as well as the default mapping for some of the pins (JTAG, SWD, UART0). Table 6-6 lists the pull configurations. Table 6-6. CC3220x Functional Configurations NAME SOP[2] SOP[1] SOP[0] SoP MODE COMMENT UARTLOAD Pullup Pulldown Pulldown LDfrUART Factory, lab Flash, and SRAM loads through the UART. The device waits indefinitely for the UART to load code. The SOP bits then must be toggled to configure the device in functional mode. Also puts JTAG in 4-wire mode. FUNCTIONAL_2WJ Pulldown Pulldown Pullup Fn2WJ Functional development mode. In this mode, 2-pin SWD is available to the developer. TMS and TCK are available for debugger connection. FUNCTIONAL_4WJ Pulldown Pulldown Pulldown Fn4WJ Functional development mode. In this mode, 4-pin JTAG is available to the developer. TDI, TMS, TCK, and TDO are available for debugger connection. UARTLOAD_FUNCTIONAL_4WJ Pulldown Pullup Pulldown LDfrUART_Fn4WJ Supports Flash and SRAM load through UART and functional mode. The MCU bootloader tries to detect a UART break on UART receive line. If the break signal is present, the device enters the UARTLOAD mode, otherwise, the device enters the functional mode. TDI, TMS, TCK, and TDO are available for debugger connection. RET_FACTORY_IMAGE Pulldown Pullup Pullup RetFactDef When device reset is toggled, the MCU bootloader kickstarts the procedure to restore factory default images.

The application can use SOP2 for other functions after chip has powered up. However, to avoid spurious SOP values from being sensed at power up, TI strongly recommends using the SOP2 pin only for output signals. The SOP0 and SOP1 pins are multiplexed with the WLAN analog test pins and are not available for other functions.

This section details the PCB guidelines to speed up the PCB design using the CC3220x VQFN device. Follow these guidelines ensures that the design will minimize the risk with regulatory certifications including FCC, ETSI, and CE. For more information, see CC3120 and CC3220 SimpleLink™ Wi-Fi® and IoT Solution Layout Guidelines.
7.2.1 General PCB Guidelines
Use the following PCB guidelines:
- Verify the recommended PCB stackup in the PCB design guidelines, as well as the recommended layers for signals and ground.
- Ensure that the PCB footprint of the VQFN follows the information in Section 9.
- Ensure that the GND and solder paste of the VQFN PCB follow the recommendations provided in CC3120 and CC3220 SimpleLink™ Wi-Fi® and IoT Solution Layout Guidelines.
- Decoupling capacitors must be as close as possible to the VQFN device.
7.2.2 Power Layout and Routing
Three critical DC/DC converters must be considered for the CC3220x device.
- Analog DC/DC converter
- PA DC/DC converter
- Digital DC/DC converter Each converter requires an external inductor and capacitor that must be laid out with care. DC current loops are formed when laying out the power components.
7.2.2.1 Design Considerations
The following design guidelines must be followed when laying out the CC3220x device:
- Route all of the input decoupling capacitors (C11, C13, and C18) on L2 using thick traces, to isolate the RF ground from the noisy supply ground. This step is also required to meet the IEEE spectral mask specifications.
- Maintain the thickness of power traces to be greater than 12 mils. Take special consideration for power amplifier supply lines (pins 33, 40, 41, and 42), and all input supply pins (pins 37, 39, and 44).
- Ensure the shortest grounding loop for the PLL supply decoupling capacitor (pin 24).
- Place all decoupling capacitors as close to the respective pins as possible.
- Power budget: The CC3220x device can consume up to 450 mA for 3.3 V, 670 mA for 2.1 V, and 700 mA for 1.85 V, for 24 ms during the calibration cycle.
- Ensure the power supply is designed to source this current without any issues. The complete calibration (TX and RX) can take up to 17 mJ of energy from the battery over a time of 24 ms.
- The CC3220x device contains many high-current input pins. Ensure the trace feeding these pins is capable of handling the following currents: – VIN_DCDC_PA input (pin 39) maximum is 1 A – VIN_DCDC_ANA input (pin 37) maximum is 600 mA – VIN_DCDC_DIG input (pin 44) maximum is 500 mA – DCDC_PA_SW_P (pin 40) and DCDC_PA_SW_N (pin 41) switching nodes maximum is 1 A – DCDC_PA_OUT output node (pin 42) maximum 1 A – DCDC_ANA_SW switching node (pin 38) maximum is 600 mA – DCDC_DIG_SW switching node (pin 43) maximum is 500 mA – VDD_PA_IN supply (pin 33) maximum is 500 mA

Figure 7-3. Ground Routing for the Input Decoupling Capacitors The ground return for the input capacitors are routed on L2 to reduce the EMI and improve the spectral mask. This routing must be strictly followed because it is critical for the overall performance of the device.
7.2.3 Clock Interfaces
The following guidelines are for the slow clock.
- The 32.768-kHz crystal must be placed close to the VQFN package.
- Ensure that the load capacitance is tuned according to the board parasitics to the frequency tolerance is within ±150 ppm.
- The ground plane on layer two is solid below the trace lanes and there is ground around these traces on the top layer. The following guidelines are for the fast clock.
- The 40-MHz crystal must be placed close to the VQFN package.
- Ensure that he load capacitance is tuned according to the board parasitics to the frequency tolerance is within ±100 ppm at room temperature. The total frequency across parts, temperature, and with aging, must be ±25 ppm to meet the WLAN specification.
- Ensure that no high-frequency lines are routed close to the crystal routing to avoid noise degradation.
- Ensure that crystal tuning capacitors are close to the crystal pads.
- Make both traces (XTAL_N and XTAL_P) as close to parallel as possible and approximately the same length.
- The ground plane on layer two is solid below the trace lines and that there is ground around these traces on the top layer.
- See CC31xx & CC32xx Frequency Tuning for frequency tuning.

7.2.4 Digital Input and Output
The following guidelines are for the digital I/O.
- Route SPI and UART lines away from any RF traces.
- Keep the length of the high-speed lines as short as possible to avoid transmission line effects.
- Keep the line lower than 1/10 of the rise time of the signal to ignore transmission line effects. This is required if the traces cannot be kept short. Place the resistor at the source end, closer to the device that is driving the signal.
- Add a series-terminating resistor for each high-speed line (such as SPI_CLK or SPI_DATA) to match the driver impedance to the line. Typical terminating-resistor values range from 27 to 36 Ω for a 50-Ω line impedance.
- Route high-speed lines with a ground reference plane continuously below it to offer good impedance throughout. This routing also helps shield the trace against EMI.
- Avoid stubs on high-speed lines to minimize the reflections. If the line must be routed to multiple locations, use a separate line driver for each line.
- If the lines are longer compared to the rise time, add series-terminating resistors near the driver for each high-speed line to match the driver impedance to the line. Typical terminating-resistor values range from 27 to 36 Ω for a 50-Ω line impedance.
7.2.5 RF Interface
The following guidelines are for the RF interface. Follow guidelines specified in the vendor-specific antenna design guides (including placement of the antenna). Also see CC3120 and CC3220 SimpleLink™ Wi-Fi® and IoT Solution Layout Guidelines for general antenna guidelines.
- Ensure that the antenna is matched for 50-Ω. TI recommends using a Pi-matching network.
- Ensure that the area underneath the BPF pads is grounded on layer one and layer two, and ensure that the minimum filter requirements are met.
- Verify that the Wi-Fi RF trace is a 50-Ω, impedance-controlled trace with a reference to solid ground.
- The RF trace bends must be made with gradual curves. Avoid using 90-degree bends.
- The RF traces must not have sharp corners.
- Do not place traces or ground under the antenna section.
- The RF traces must have via stitching on the ground plane beside the RF trace on both sides.
