I found this data sheet for a for a RTC and it's intentionally comprehensive. lol
https://www.nxp.com/docs/en/data-sheet/PCF8583.pdf
As far as memory/buses goes I want to use something that is a balance of function and complications.It has to be a balance of practicability. I imagine if successful I will have to build or modify at least 3 data loggers. The last one would have a character screen to get data from.
So basically when using a RTC you are tethering two IC's together and using the RTC to signal the PIC.
