FOR AUTOMOTIVE 105°C OPERATION
3-WIRE REAL-TIME CLOCK
Rev.2.2_02
The S-35190A H Series is a 105C operation 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-35190A H Series 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-35190A H Series 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-35190A H Series 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.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to ABLIC Inc. is indispensable.
