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.
