7.4 Pin Attributes and Pin Multiplexing

The module 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 module reset) and register control.

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 7-3 describes the general pin attributes and presents an overview 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. Drive strength is individually configurable for each pin.
  • All I/Os support 10-μA pullup and pulldown resistors.
  • By default, all I/Os float in the Hibernate state. However, the default state can be changed by SW.
  • All digital I/Os are non fail-safe.

Note:

If an external device drives a positive voltage to the signal pads and the CC3220MODx or CC3220MODAx modules are 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 CC3220MODx or CC3220MODAx modules can occur. To prevent current draw, TI recommends any one of the following conditions:

  • All devices interfaced to CC3220MODx and CC3220MODAx modules 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 CC3220MODx and CC3220MODAx modules must be held low until the VBAT supply to the module 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.

(1) LPDS state: The state of unused I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(2) Hibernate mode: The state of the I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(3) To minimize leakage in some serial Flash vendors during LPDS, TI recommends that the user application always enables internal weak pulldowns on FLASH_SPI_DIN, FLASH_SPI_DOUT, and FLASH_SPI_CLK pins.
(4) 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.
(6) Pin is one of three that must have a passive pullup or pulldown resistor onboard to configure the chip hardware power-up mode. For this reason, the pin must be output only when used for digital functions.
(7) This pin is reserved for WLAN antenna selection, controlling an external RF switch that multiplexes the RF pin of the CC3220MODx module between two antennas. These pins must not be used for other functionalities.
(8) Device firmware automatically enables the digital path during ROM boot.
(9) Requires user configuration to enable the analog switch of the ADC channel. (Switch is off by default.) The digital I/O is always connected and must be made Hi-Z before enabling the ADC switch.
(10) Pin is shared by the ADC inputs and digital I/O pad cells.
Note:

The ADC inputs are tolerant up to 1.8 V (see Section 8.14.5.6 for further details on the useable range of the ADC). 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 47], S8 [Pin 48], S9 [Pin 49], and S10 [Pin 50]). For more information, see Section 7.5.
