Information regarding rtc in ESP32-S2

Postby sabin.john » Tue Nov 23, 2021 6:58 am

I want to understand how to keep RTC clock working while chip logic is off(if possible) in the esp32-s2. I know this is not possible in the esp32, hence I am considering the s2. I am attaching two images below to highlight the difference. What's special about the RTC Analog domain block? Can it work standalone when the chip is off?
Regards,
Sabin

Hello, S2 is same with 32, RTC part could not work independently.
