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 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...
