Description

The UM66 / BT66 Melody IC is a CMOS LSI (Large Scale Integration) designed to generate musical tones. The IC contains a built-in oscillator and a ROM (Read-Only Memory) that stores the melody data. When powered, the IC plays a specific melody continuously or just once, depending on the circuit configuration. The output can drive a small speaker directly or be fed into an amplifier for louder sound.

The IC is extremely easy to use, requiring only a few external components, making it ideal for low-cost, simple melody generation applications.

Features

  • Pre-programmed Melody: Contains a pre-stored melody that is played back when the IC is powered on.
  • Low Power Consumption: Operates efficiently with minimal power, ideal for battery-powered devices.
  • Simple Circuit Design: Requires only a few external components, making it easy to design and implement.
  • Direct Speaker Drive: The IC can directly drive a small speaker or be connected to an amplifier for higher output.
  • Built-in Oscillator: Includes an internal oscillator, simplifying the circuit design and reducing the need for external clock sources.
  • Wide Operating Voltage Range: Typically operates within a 1.5V to 3V range, making it suitable for various battery-powered applications.
  • Compact TO-92 Package: The small, three-pin package makes it easy to integrate into space-constrained designs.

Specifications

  • Melody: Pre-programmed (varies by model, different melodies available)
  • Operating Voltage: 1.5V to 3V (typical)
  • Output Frequency: Varies depending on the melody and the specific model of the IC
  • Output Type: Digital square wave, suitable for driving a small speaker or further amplification
  • Current Consumption: Less than 1 mA (typical)
  • Package Type: TO-92 (3 pins)
  • Operating Temperature: -20°C to +70°C

Applications

  • Toys: Commonly used in electronic toys to produce musical tones or sound effects.
  • Doorbells: Integrated into electronic doorbell circuits to provide a pleasant chime when the button is pressed.
  • Alarms: Used in alarm systems to generate a warning sound or musical alert.
  • Greeting Cards: Implemented in musical greeting cards to play a melody when opened.
  • DIY Electronics Projects: Popular among hobbyists for creating simple musical circuits.
