Hello,
I am designing with the aforementioned RTC and have the following questions. I contacted ST support and the solution was to ask the forums. So here are my questions:
- What is the date output (i.e. binary, BCD, YY:MM:DD:dd, HH:MM:SS:hh, etc.)?
- The crystal and battery are in a separate module and are not integrated with the IC itself. I want to make sure that it is compatible with both types (the 48 and 120 mAh).
- What does the chip control in terms of the NVSRAM? Is it a buffer? What does it do?
- Unrelated to this chip in particular, does ST have a RTC with an integrated (non-seperate SNAPHAT) crystal and no battery pin, just VDD? I do not need a backup battery, or a pin for it.
Thank you
