Time

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

(refer to Table 8).

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.
