UTC UM66TXXL
MELODY INTEGRATED CIRCUIT
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 additional components.
