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-35740 Series outputs the fixed-cycle interrupt signal. The frequency and duty ratio of the fixed-cycle interrupt signal

can be set freely by users via a 2-wire serial interface.

Moreover, the S-35740 Series has a built-in 24-bit timer. For example, users can obtain the cumulative energization time of

the system since the timer performs a count-up action every second.

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.
