General Description
UM3561 is a low-cost, low-power CMOS LSI designed for use in alarm and toy applications. 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.
