The wake-up timer IC allows for intermittent system operation by periodically waking up the system.

The S-35720 Series compares the timer value and the value set to the SET0 pin and the SET1 pin, and outputs a wake-up

signal (interrupt signal) when the values match each other.

The timer of the S-35720 is a 24-bit binary-up counter.

4 types of wake-up time (interrupt time) can be selected depending on the SET0 pin and the SET1 pin settings.
