General Description
The UM66T series is a CMOS LSI designed melody generator IC for use in telephones and toys
application. It has an on-chip ROM programmed for musical performance. Produced by CMOS
technology, the device results in very low power consumption. And with built-in RC oscillator, a
compact melody module can be constructed with only a few additional components.
