Manufacturer:

Mitsubishi Electric (MIT)

Part Number:

M65830P, M65830AP, M65830BP

Description:

The M65830P/AP/BP is a digital echo processor IC designed for audio applications, particularly in karaoke systems, audio effects processors, and other sound enhancement devices. It provides high-quality digital echo and reverberation effects with adjustable parameters.

Key Features:

• Digital Echo Processing: Supports adjustable delay times for echo effects.
• Built-in ADC/DAC: Includes an 8-bit ADC (Analog-to-Digital Converter) and a 10-bit DAC (Digital-to-Analog Converter).
• Sampling Frequency: Supports a sampling frequency of up to 500 kHz.
• Delay Time Adjustment: Adjustable delay time up to 204.8 ms (dependent on external memory configuration).
• Low Noise: Designed for high signal-to-noise ratio (SNR) performance.
• Low Power Consumption: Suitable for portable and consumer audio applications.
• External Memory Support: Requires external DRAM (e.g., 256K-bit or 1M-bit) for delay processing.
• Control Interface: Can be controlled via serial or parallel interface.

Applications:

• Karaoke systems
• Audio effects processors
• Musical instruments
• Sound reinforcement systems

Package:

• M65830P: DIP (Dual In-line Package)
• M65830AP/BP: Likely variations in packaging or performance grades (exact differences may depend on datasheet specifications).
