Download the UM66T08L datasheet PDF (UM66Txx included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for melody integrated circuit.

Description

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.

Features

  • S.
  • 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.
