3.
2_04 The S-35192A is a CMOS 3-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-35192A can be used for various power supplies from main supply to backup battery.
Due to the 0.
45 A current consumption and wide range of power supply voltage at time keeping, the S-35192A 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-35192A 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 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.
