Part Name(s) : STA331 STA331-EVAL ST-Microelectronics
STMicroelectronics
Description : HIGH EFFICIENCY CLASS D CODEC WITH INTEGRATED AUDIO PROCESSING

Description
The STA331 device is a HIGH-EFFICIENCY AUDIO CODEC WITH an INTEGRATED ARM7TDMI® core capable of running AUDIO PROCESSING algorithms up to 75 MHz. The surrounding analog and digital AUDIO peripherals turn it in the ideal and flexible solution for mid-range sound PROCESSING applications, where final product differentiation is a must. The code runs off from
the embedded RAM, uploaded by an external serial flash and the whole set of AUDIO parameters and functionalities may be controlled via I2C or customizable GPIO interface (for micro-less operation). Moreover, the widely adopted core allows for a fast porting of third-parties AUDIO effects, typically available on ARM® processors.

Features
HIGH EFFICIENCY CLASS D FFXTM technology.
■ Stereo ADC input WITH INTEGRATED microphone bias
■ Digital/analog I/O muxing and down-mixing capability
■ Low power architecture

Description : Low-Power AUDIO CODEC WITH AUDIO PROCESSING and Stereo CLASS-D Speaker Amplifier

Description
The TLV320AIC3110 device is a low-power, HIGHly INTEGRATED, HIGH-performance CODEC that supports stereo AUDIO DAC, and mono AUDIO ADC.
The TLV320AIC3110 device features a HIGH-performance AUDIO CODEC WITH 24-bit stereo playback and monaural record functionality. The device integrates several analog features, such as a microphone interface, headphone drivers, and speaker drivers. The digital-AUDIO data format is programmable to work WITH popular AUDIO standard protocols (I2S, left-justified and right-justified) in master, slave, DSP, and TDM modes. Bass boost, treble, or EQ is supported by the programmable digital-signal PROCESSING blocks (PRB). An on-chip PLL provides the HIGH-speed clock required by the digital-signal PROCESSING block. The volume level is controlled either by pin control or by register control. The AUDIO functions are controlled using the I2C serial bus.
The TLV320AIC3110 device has a programmable digital sine-wave generator and is available in a 32-pin VQFN package.
