AM623: Power consumption with RTC function

Hi Austin.Chen,

If AM62x doesn't support RTC-Only mode. Which power management mode that RTC function is still workable?

The RTC is within the "Always On" domain, which is powered on in DeepSleep, MCU Only, and Standby power modes.

austin.chen said:

Do you have the power consumption test data about that mode?

We have not formally published these metrics yet as the power measurements are still being optimized in the Linux driver development. 

Do you have a particular power mode that you are most interested in?

Hi Colin

We are trying to use internal RTC to keep RTC data, so we have to minimize the power consumption and have smallest battery capacity.

Partial IO mode seems the lowest power mode.

Can Partial IO mode keep RTC data?

How about the power consumption for this mode?

Unfortunately only DeepSleep and MCU Only Mode retain the RTC domain. 

We do not have formal power measurements for MCU Only mode yet to publish.

DeepSleep is targeting about 16mW when VDD_CORE is set to 0.75V.
