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

The S-35710M compares the timer value and the value written to the internal register, and outputs a wake-up signal (interrupt

signal) when the values match each other.

The timer of the S-35710M is a 24-bit binary-up counter.

The internal register data can be set freely by users via a 2-wire serial interface. Consequently, the time before the occurrence

of a wake-up signal (interrupt signal) can be set freely.

Since the S-35710M has a built-in quartz crystal, a matching assessment of the IC and the quartz crystal is unnecessary.

Moreover, the number of external parts can also be reduced.
