For Automotive 125°C Operation 2-wire Convenience Timer S-35710 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-35710 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 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.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII is indispensable.
