2-WIRE REAL-TIME CLOCK

The S-35390A is a CMOS 2-wire real-time clock IC which operates with the very low current consumption and in the wide
range of operation voltage. The operation voltage is 1.3 V to 5.5 V so that this IC 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 supply voltage at time
keeping, this IC 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 which is
stored before power-off the main power supply, after the voltage is restored.
This IC has the function to correct advance/delay of the clock data speed, in the wide range, which is caused by the oscillation
circuit’s frequency deviation. Correcting according to the temperature change by combining this function and a temperature
sensor, it is possible to make a high precise clock function which is not affected by the ambient temperature.
