Description:

Simple Melody Generator

Features

* n 62-note ROM memory n 1.3V to 3.3V operating voltage and low power con- sumption n Dynamic speaker can be driven with an external NPN transistor. n OSC. resistor is built- in n One-shot mode or level-hold mode can be selected n Power on reset; melody begins from the first note n Direct piezo drive

Applications

* It is an on-chip ROM programmed for musical performance. Produced by CMOS technology, the device results in very low power consumption. Since the UM66T series includes oscillator and mode selector circuits, a compact melody module can be constructed with only a few additional components. Pin Conf
