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-35710 Series 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-35710 Series 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.
