Hi every one

 

Im working with DSP "ADSPBF527BBCZ-5A"

I want to choose a supercap for the RTC so it can last at least 7 days

The fact is that i find the RTC's current consumption too high (Datasheet data) 20uA at 3v3

I want to make sure this is not a max value or under certain conditions.

Can anyone take a look and tell me your opinion.
