Package includes: 1 piece UM3561 IC


UM3561 is a low-cost, low-power CMOS LSI designed for use in alarm and toy applications (a three siren sound generator). Since the integrated circuit includes oscillator and selector circuits, a compact sound module can be constructed with only a few additional components. The M3561 contains a programmed mask ROM to simulate siren sound.
