Compatibility & sourcing notes
The DS1307 and RV-8564 are not interface-compatible: the DS1307 uses I²C address 0x68 with a different register layout, is 5V-only with an external crystal and no alarm, whereas the RV-8564 is at 0xA2, 1.2~5.5V with an embedded crystal, alarm, and timer. Both firmware and PCB must be reworked — a functional alternative, useful when migrating off the older/5V DS1307.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
