Hi,
we are running the OMAP-L138 at 456 MHz (CVDD=1.3V), but are not using RTC. We are using a 2% regulator for the 1.3V (that we'd like to keep), so we cannot tie RTC_CVDD to CVDD without exceeding the 1.32V max recommended operating condition for RTC_CVDD, and therefore keep it on a separate regulator.
For power sequencing, the Application Report slva371b states that RTC_CVDD can be included in the static 1.2V supply domain - see note (5):
Therefore, our sequencing would look like this:
Is this a valid sequence or is the Application Report outdated?
Thanks,
Joern
