Vbat to the RTC is specified as max of 5.5V, are you supplying the full battery voltage? Would a supercap be useful?
Mike.
You are correct , The RTC can only handle 5.5V ...so now we need a battery source.
There is no room for a supercap...
It looks like the Addition of the RTC will raise the final sales price by over $10.
I do not feel this is worth it for what it provides.
If you need time and date logging then you could enter it into the Radio , or Link up with some other Time source.
I could leave a spot on the board for the parts ...and it would be up to the end user to get and install them if desired.
Thoughts?
