Convenience Timer, Automotive, 125°C Operation, 2-Wire Timer with Built-in Quartz Crystal S-35710M A Series

The convenience timer is a CMOS timer IC which operates with low current consumption, and is suitable for the time management of the relative time.
The S-35710M A Series compares the timer value and the value written to the internal register, and outputs an interrupt signal when the values match each other.
The timer of the S-35710M A 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 an interrupt signal can be set freely.
Since the S-35710M A Series 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.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product for these purposes, it is imperative to contact our sales representatives.
