Mechanical and electrical specifications

2.2.1

Recommended power-up sequence

For the power-up sequence please refer to the following figure, where:



Trise is the time for the power supply to rise from 10% to 90% of its final value



Twait is the time delay between the end of the Vdd_IO ramp (90% of its final value) and

the start of the Vdd ramp

In the power-down sequence Vdd and Vdd_IO can come down in any order.
