S-35710 A Series CONVENIENCE TIMER AUTOMOTIVE, 125C OPERATION, www.ablic.com 2-WIRE TIMER ABLIC Inc., 2014-2020 Rev.2.1 00 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 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 an interrupt signal can be set freely. 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.
