CONVENIENCE TIMER
© SII Semiconductor Corporation, 2016
Rev.1.0_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-35730 Series outputs the clock pulse.
4 types of clock pulse frequency can be selected from 1 Hz to 32.768 kHz 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 in the
purpose, contact to SII Semiconductor Corporation is indispensable.
