2-WIRE REAL-TIME CLOCK
Rev.2.1_03
The S-35391A 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-35391A 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-35391A 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. The S-35391A has the function to correct advance / delay of the clock data speed, in the wide range, which is caused by the crystal oscillation circuit's frequency deviation. Correcting according to the temperatu...
