S-35392A www.sii-ic.com © SII Semiconductor Corporation, 2006-2016 2-WIRE REAL-TIME CLOCK Rev.3.2_02 The S-35392A 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-35392A can be used for various power supplies from main supply to backup battery.

Due to the 0.45 μA current consumption and wide range of power supply voltage at time keeping, the S-35392A makes the
