Description
The CS4811 is a complete audio effects processing system on a chip. This device integrates a proprietary 24-bit audio processing engine, large on-chip RAM memories, and a high performance 24-bit audio codec. A serial control port allows the device to boot firmware from a compact and low cost SPI or I2C serial EEPROM. Other features such as single +5 V operation simplify system design.
