The S-35390A is a low-current-consumption 2-wire CMOS real-time clock IC that features a wide operating voltage range (1.3 V to 5.5 V) and can be driven on a variety of supply voltages, from a main supply to a backup supply. The time keeping current consumption of 0.25 µA and time keeping operation voltage of 1.1 V enable greatly increased battery duration. In a system that operates on a backup battery, the free register incorporated in the real-time clock can be used for the user backup memory function.
