(mask Option) ._ ~... - _.a - General Description The UM3561 is a lowcost, tow-power CMOS LSI designed tor use in toy applications. Since the integrated circuit includes oscillator and selector circuits, a compact sound module tan be constructed with cnly a few additionol components. The UM3581 contains a programmed mask ROM to simulate siren sounds.
