S-35399A03 www.sii-ic.com © SII Semiconductor Corporation, 2007-2016 2-WIRE REAL-TIME CLOCK Rev.3.1_02 The S-35399A03 is a CMOS 2-wire real-time clock IC which operates with the very low current consumption in the wide range of operation voltage. The operation voltage is 1.3 V to 5.5 V so that the S-35399A03 can be used for various power supplies from main supply to backup battery. Due to the 0.34 μA current consumption and wide range of power supply voltage at time keeping, The S-35399A03 makes the battery life longer. In the system which operates with a backup battery, the included free registers can be used as the function for user's backup memory.
