Hi team,
I would like to ask about RTC backup of i.MX28.
In i.MX28 reference manual, it is said as below.
“The RTC can continue to count time as long as a voltage is applied to the BATT pin…”
And i.MX28 datasheet says that BATT and the minimum voltage of DCDC_BATT pins is 3.1V.
I read the following discussion in i.MX community but please let me clarify about that again.

Can I understand that BATT and DCDC_BATT pins have to be fed 3.1V at least for keeping internal RTC alive?
If any other concerns, please let me know.
Thanks,
Miyamoto

Hi Miyamoto
for keeping RTC sufficient only voltage applied to the BATT pin.
