Battery backup for RTC only?

Hi,

I know about the possibility to add a battery to power the full board (the four pins close to the power jack). But is there also a possibility to install a battery backup for RTC clock of AM3358? Means only the RTC, not the full board?

Thanks!

Same battery as the whole board. The AM3358 standby current is higher than adding an external RTC with a battery.
