6.2 Pin Attributes

Table 6-1 lists the pin descriptions of the CC3120MOD module.

Note:

If an external device drives a positive voltage to signal pads when the CC3120MOD is not powered, DC current is drawn from the other device. If the drive strength of the external device is adequate, an unintentional wake up and boot of the CC3120MOD can occur. To prevent current draw, TI recommends one of the following:

  • All devices interfaced to the CC3120MOD must be powered from the same power rail as the CC3120MOD.
  • Use level-shifters between the CC3120MOD and any external devices fed from other independent rails.
  • The nRESET pin of the CC3120MOD must be held low until the VBAT supply to the module is driven and stable.
