General Description
The UM66T-08S is a CMOS LSI designed melody generator IC for use in door bells , toys and other
consumer products, which require auto-stop playing function. It has an on-chip ROM programmed for
musical performance. Produced by CMOS technology, the device results in very low power
consumption. And with built-in oscillator, a compact melody module can be constructed with only a
few additional components.
•
OSC resistor is built-in.
•
One-shot
mode to play and auto stop
•
Dynamic speaker can be driven with
external NPN transistor.
