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 serie nclude oscillation circuits a compact melody module can be constructed with only a few additional components.
