STMicroelectronics STA331
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).FEATURES
