Hello Champs,
There is a power-up order for NVCC_SRTC and VCC.
Howerver, there is no specific timing for the between the two.
My customer would like to power-up the both at the same time.
Is it workable?
Best regards,
Nori Shinozaki

Hi Nori
datasheet recommends to power first NVCC_SRTC,
so powering power-up the both at the same time is not
recommended, sorry. Regarding specific timing, next power-up
sequence may start when NVCC_SRTC reached 90% level,
as described in AN4053 i.MX51 Power-Up Sequence
(one can folow that with i.MX50 power-up sequence too).
Best regards
