Figure 7: Power-up Requirements

When powering up a device, the VCC/VCCIO rails must take 400 µs or longer to reach the

maximum value (refer to Figure 7).

NOTE: Ramping VCC/VCCIO to the maximum voltage faster than 400 µs can cause the

device to behave improperly.

For users with a limited power budget, keep (VCCIO -VCC)MAX ≤ 500 mV when ramping up

the power supply.
