PS2 uses either a dedicated Ricoh RS5C348A RTC (these consoles have a separate Rohm BR9080F EEPROM) or a combined EEPROM+RTC IC (Rohm BU9861FV-WE2). GH-001 to GH-014 and GH-016 always have separate ICs, GH-015 can have either, GH-017 to GH-022 always have the combined IC. On consoles with a Dragon-[[MechaCon]] (GH-023 and any later board), a combined EEPROM+RTC IC die is inside the chip case of MechaCon itself.
