14.3.2 Supply sequencing requirements

The various supplies and BUCKEN need to be sequenced in order with delay requirements.

The power up sequence and requirements are:

• Supply VBAT/BUCKVBAT/BUCKVBATS/AFEVBAT

• Wait ≥ 6 ms

• Assert BUCKEN

• Wait ≥ 1 ms

• Supply IOVDD

PWRIOVDD is an internally generated supply, used for supplying OTPVDD through an external connection.

It cannot be used for anything else. This supply is automatically controlled in the device.

The power-down sequence and requirements are:

4486_184 v1.0
