Description

The UM66T series is a CMOS LSI designed melody generator IC for use in telephones and toys application. 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 RC oscillator, a compact melody module can be constructed with only a few additional components

Features

• 64-note ROM memory · Bulit-in RC oscillator
• 1.3V to 3.3V operating voltage
• Low power consumption
• TO-92 package
• Bulit-in RC oscillator
• Level-hold mode to play repeatedly
•  Dynamic speaker can be driven with  external NPN transistor.
