RTC under power down

[AsafTv]

Hi,

I use MK64FN1M0xxx12 Device

I want to know if the device will be put in power down and vbat is driven if the RTC will continue to work even vdd is disconnected.

is vbat value is depend on vdd value.

Hi @AsafTv 

Thank you so much for use our community. I really appreciate your patience.

Regarding your question, effectively, Vbat is an external voltage that can be used for the RTC even though the Vdd for the whole system is disconnected, so the RTC can still be working.

Hoping this information is helpful, please let me know if you have more questions.

Sincerely,
Pablo Avalos.
