Hi,

Is there have Power on sequence requirement for 1.8V and 1.17V?

I can't find relative requirement in datasheet.

    Hi Jeff,

    Although there are no specific power sequencing requirements for these supplies, in general it would be recommended to ramp the 1.17V supply first if both cannot be ramped at the same time.  This will ensure the core is powered before the IO, but no issues have been observed by not following this sequence.
