Melody Integrated Circuit
Description
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.
