UM66T Datasheet, Pinout, and Melody List

What is the UM66T?

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.

UM66 IC 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
