Power Up Requirements

Power supply sequencing is not required if you are configuring

VDDQ = 3.3 V and all power supplies pins are connected to the

same 3.3 V power supply.

Power supply sequencing is required if you are configuring

VDDQ = 1.5 V. Power is applied in the following sequence: VCC

(3.3) followed by VDDQ (1.5). Power supply ramping may occur

simultaneously as long as the VCC/VDDQ relationship is

maintained.
