The M65847FP is a digital echo processor LSI (Large Scale Integration) from Mitsubishi Electric. It's specifically designed for audio applications requiring echo and reverb effects. The chip incorporates delay lines, modulation circuits, and control logic to create various sound effects, making it suitable for karaoke systems, audio mixers, and electronic musical instruments.

Applications:

• Karaoke Systems
• Audio Mixers
• Electronic Musical Instruments (e.g., synthesizers, digital pianos)
• Audio Effects Processors
• Public Address (PA) Systems

Features:

• Digital Delay Lines: Creates the echo effect by delaying the audio signal.
• Modulation Circuits: Adds variations to the delay time for chorus and flanger effects.
• Built-in AD/DA Converters: Simplifies interfacing with analog audio signals.
• Control Logic: Allows for adjusting echo time, feedback, and other parameters.
• Low Noise and Distortion: Ensures high-quality audio output.

Benefits:

• Versatile Sound Effects: Creates a wide range of echo, reverb, and chorus effects.
• Simplified System Design: Integrated AD/DA converters reduce external component count.
• High-Quality Audio: Low noise and distortion ensure clean and clear sound output.
• Easy Control: User-friendly interface allows for easy adjustment of effect parameters.
• Compact Solution: Single-chip solution reduces board space and cost.
