Power off sequence.

[takashitakahash]

Hi community.

Our customer has below question.

The iMX6 is not specified of  power off sequence.

Phenomenon caused by the discharge of the capacitor speed and capacitance connected to the power supply.

For example, NVCC_EIM0 ~ 2 is at 3.3v, even if VDDARM_IN is like that 0.5v, Will it not be a problem?

If POR_B is negated, Would never like that, iMX6 to malfunction or failure?

Hi Takashi

no problem, as according to sect.4.2.2 Power-Down Sequence

i.MX6DQ Datasheet (rev.4, 7/2015)

No special restrictions for i.MX 6Dual/6Quad SoC.
