UM66T19LK-1 IC TO92 UTC Melody Generator Musical Alarm

Product Overview

A low-power CMOS melody integrated circuit (IC) designed for use in door bell, telephone, and toy applications. It features an on-chip mask ROM programmed for musical performance, capable of memorizing a 64-note melody. Because it includes built-in oscillation circuits, a compact melody module can be constructed with only a few additional components. The device also incorporates a power-on reset function so that the melody always begins from the first note, a built-in level hold mode, and an output pin capable of driving a buzzer directly or a dynamic speaker via an external NPN transistor.
