Please contact each Web shop for details such as availability of online samples.

The interval timer IC allows for intermittent system operation by inputting a signal to the system at fixed periods of time.
The S-35730 outputs the interval signal (clock pulse).
One interval signal (clock pulse frequency) can be selected from “32.768 kHz”, “32 Hz”, “1.024 kHz”, and “1 Hz” according to the SET0 pin and the SET1 pin settings.
