S-35720 A Series CONVENIENCE TIMER AUTOMOTIVE, 125C OPERATION, www.ablic.com TIMER WITH INTERRUPT TIME SETTING PIN ABLIC Inc., 2015-2020 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-35720 Series compares the timer value and the value set to the SET0 pin and the SET1 pin, and outputs an interrupt signal when the values match each other. The timer of the S-35720 Series is a 24-bit binary-up counter. 4 types of interrupt time can be selected depending on the SET0 pin and the SET1 pin settings. 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. Features Alarm interrupt function: Settable interrupt time Selectable as the option on the second time scale from 1 second to 194 days (Approximately half a year) Low current consumption: 0.2 A typ. (Quartz crystal: C = 6.0 pF, V = 3.0 V, Ta = +25C) L DD Wide range of operation voltage: 1.8 V to 5.5 V Built-in 32.768 kHz crystal oscillation circuit Operation temperature range: Ta = 40C to +125C Lead-free (Sn 100%), halogen-free *1 AEC-Q100 qualified *1.
