Range – On-chip 24-bit ∆Σ DAC with 100 dB Dyn. Range – Automatically boots firmware from external serial EEPROM l Firmware available for Guitar Effects or Mixer Effects applications l Single +5 V Supply l 100-pin Metric Quad Flat Pack (MQFP) 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. Firmware for the CS4811 is provided by Cirrus Logic. There are two different firmware codes available; one for guitar effects and one for audio mixers. The guitar effects firmware provides a host of electric guitar effects includ- ing spring reverb, delay, chorus, flange and tremolo. The mixer effects firmware provides a suite of effects such as digital reverb, delay and chorus which are suit- able for use in audio mixers, karaoke and acoustic instrument amplifiers. The CDB4811GTR and CDB4811MXR evaluation boards allow easy evaluation of the CS4811 device and the associated firmware.
