super-cap with MIMXRT1176CVM8A

[EBA1]

Hello,

I'm using the MIMXRT1176CVM8A  and I need to back up the power supply with a supercap? Is there any guidelines recommendation or schematic that can help me to implement the super-cap and respect the power down sequence requirement ?

Thank you in advance!

Hi @EBA1 ,

    We don't have the super-cap schematic.

   In fact, no matter what you used, you need to match this power on sequency:

I think power down is OK, just when you add the super cap, you need to meet the power on requirement in the DS:

Best Regards,
