Compatibility & sourcing notes
Not pin-compatible: the RV-3028-C7 is an ultra-low-power I²C RTC (~45nA timekeeping vs DS3231 ~840nA, PCF8563 ~250nA) for battery devices. DS3231 keeps a wide-temperature TCXO edge; a firmware port is needed.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
