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

Available Applications
Automotive ICs are categorized according to their application. The following symbols indicate the types of applications for which an IC can be used.
Safety critical components typified by engine, transmission, suspension and ABS, and EV/HEV/PHEV related equipment, etc.
Meter, body, headlamp, ITS, etc.
Accessory, car navigation, car audio system, etc.

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.
