The convenience timer is a CMOS timer IC which operates with low current consumption, and is suitable for the time

management of the relative time.

The S-35720 Series compares the timer value and the value set to the SET0 pin and the SET1 pin, and outputs an interrupt

signal when the values match each other.

The timer is a 24-bit binary-up counter.

4 types of interrupt time can be selected depending on the SET0 pin and the SET1 pin settings.

Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the

purpose, contact to SII is indispensable.
