            UM66TXXL UM66T05L UM66T08L UM66T11L UM66T19L UM66T32L Datasheet

            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.

            *64-Note Rom memory
            *1.5V ~ 4.5V power supply and low power consumption
            *Dynamic speaker can be driven with external NPN transistor
            *OSC resistor hold mode
            *Power on reset: melody begins from the first note
            *Built in level hold mode
