S-35390A Overview
© SII Semiconductor Corporation, 2004-2016 2-WIRE REAL-TIME CLOCK Rev.4.2_02 The S-35390A 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-35390A can be used for various power supplies from main supply to backup battery. Due to the 0.25 μA current consumption and wide range of power...
