Pin-selectable Wake-up Timer IC S-35720 Series

Wake-up Timer IC - Intermittent operation enables significantly reduce system power consumption
Wake-up Timer IC – Intermittent operation enables significantly reduce system power consumption

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.
