6.2 Pin Attributes

Table 6-1 describes the CC3135 pins.

Note:

Digital IOs on the CC3135 device refer to hostless mode, BLE/2.4GHz coexistence, and antenna select IOs, not general-purpose IOs.

If an external device drives a positive voltage to signal pads when the CC3135 device is not powered, DC current is drawn from the other device. If the drive strength of the external device is adequate, an unintentional wakeup and boot of the CC3135 device can occur. To prevent current draw, TI recommends one of the following:

  • All devices interfaced to the CC3135 device must be powered from the same power rail as the CC3135 device.
  • Use level shifters between the CC3135 device and any external devices fed from other independent rails.
  • The nRESET pin of the CC3135 device must be held low until the VBAT supply to the device is driven and stable.

(2) 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.
