UM66T19LK-T92-K:MELODY INTEGRATED CIRCUIT
The UTC UM66T19LK 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
