Compatibility & sourcing notes
The PCF85063A and RV-3028-C7 are both small I²C RTCs, but they are not register-compatible: the I²C address differs (0x51 vs 0x52) and the time-register offset differs (04h vs 00h), plus the RV-3028 adds EEPROM-stored config, a UNIX-time counter, and automatic backup switchover. A new driver is required — a functional alternative whose selling point is ultra-low power (~45nA).
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
