Rev.1.0_00 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. Features
• Wake-up function
(Alarm interrupt function):
