Electrical Characteristics
4.2
Any MCIMX31 board design must comply with the power-up and power-down sequence guidelines as
described in this section to guarantee reliable operation of the device. Any deviation from these sequences
may result in any or all of the following situations:
4.2.1
The Power On Reset (POR) pin must be kept asserted (low) throughout the power up sequence. Power up
logic must guarantee that all power sources reach their target values prior to the release (de-assertion) of
POR.

Supply Power-Up/Power-Down Requirements and Restrictions
Powering Up
Stages need to be performed in the order shown; however, within each stage,
supplies can be powered up in any order. For example, supplies IOQVDD,
NVCC1, and NVCC3 through NVCC10 do not need to be powered up in the
order shown.
NVCC6 and NVCC9 must be at the same voltage potential. These supplies
are connected together on-chip to optimize ESD damage immunity.
