General Description
The UM88T series is a CMOS LSI designed melody generator IC with accompaniment for use in
telephones and toys application. It has an on-chip ROM programmed for dual-tone 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.
