S-35710M A Series CONVENIENCE TIMER AUTOMOTIVE, 125C OPERATION, www.ablic.com 2-WIRE TIMER WITH BUILT-IN QUARTZ CRYSTAL ABLIC Inc., 2017-2020 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-35710M 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 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 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.
