STA331 Datasheet High Efficiency Class D Codec

Manufacturer: STMicroelectronics

Overview: STA331 www.datasheet4u.com High efficiency class D codec with integrated audio processing Data.

General Description

STi1000 1 www.datasheet4u.com 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 soundprocessing 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).

Key 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 I/O supply voltage range: 1.8 V to 3.6 V Programmable GPIO functionalities for microless operation Audio processing libraries:.
  • tones, WideSurround, StereoEnhancer.
  • intelligent volume control (MDCR).
  • enhanced listening modes (voice, midnight modes).
  • MP.
