MELODY INTEGRATED CIRCUIT
CMOS IC

DESCRIPTION


The UTC UM66TXXL series are CMOS LSI designed for using
in door bell, telephone and toy application. It is an on-chip ROM
programmed for musical performance. Produced by CMOS
technology, the device results in very low power consumption.
Since the UTC UM66TXXL series include oscillation circuits a
compact melody module can be constructed with only a few
1
additional components.
