3 Terminal Configuration and Functions

Figure 3-1 shows pin assignments for the 64-pin QFN package.

3.1 Pin Attributes

Table 3-1 describes the CC3100 pins.

NOTE

If an external device drives a positive voltage to signal pads when the CC3100 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 CC3100 device can occur. To prevent current draw, TI recommends one of the following:

  • All devices interfaced to the CC3100 device must be powered from the same power rail as the CC3100 device.
  • Use level-shifters between the CC3100 device and any external devices fed from other independent rails.
  • The nRESET pin of the CC3100 device must be held low until the VBAT supply to the device is driven and stable.
