S-35390A Datasheet | ABLIC

.ablicinc. © ABLIC Inc., 2004-2016 2-WIRE REAL-TIME CLOCK Rev.4.2_03 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 A current consumption and wide range of power supply voltage at time keeping, the S-35390A 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. Users always can take back the information in the registers...
