Hello,

I am working with the CC2652R1 and I want to develop an application ultra low power with a calendar.

Does the CC2652R1 has a pin like Vbat, which will power the rtc module when it is in sleep mode ?

The idea is using a bottom battery for lasting some years. When it is not in sleep mode it is powered by another battery. In this way we could leave the device only with the bottom battery and the RTC will be always on without losing the calendar.

Thank you,

Best regards,

Sebastian

Hi Sebastian,

There is no "back-up battery" feature like that available on the device. This is something you would need to handle externally if you want to be able to switch between batteries (using some kind of power-mux).
