4.11 Timing and Switching Characteristics
4.11.1 Power Supply Sequencing
For proper operation of the CC3200 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 (100K ||
0.1 µF, RC = 10 ms).
3. For an external RTC clock, ensure that the clock is stable before RESET is deasserted (high).
For timing diagrams, see Section 4.11.2, Reset Timing.
