Please contact each Web shop for details such as availability of online samples.


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 A 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 of the S-35720 A Series 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 for these purposes, it is imperative to contact our sales representatives.
