UM66T05L - Melody Integrated Circuit

Download the UM66T05L datasheet PDF. This datasheet also covers the UM66Txx variant, as both devices belong to the same melody integrated circuit family and are provided as variant models within a single manufacturer datasheet.

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

  • 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 CMOS IC 1 TO-92 1: VSS 2: VDD 3: O/P(Melody output).
