General Description The UM66T series is a CMOS LSI designed for use in door bells, telephones and toy applications. It is an on-chip ROM programmed for musical performance. Produced by CMOS technology, the device results in very low power consumption. Since the UM66T series includes oscillator and mode selector circuits, a compact melody module can be constructed with only a few additional components.
