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 pact melody module can be constructed with only a few additional ponents. Features - 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 CMOS IC 1 TO-92 1: VSS 2:...
