TLV320AIC3256EVM-U Datasheet PDF - TI

●The TLV320AIC3256EVM-U is a complete evaluation/demonstration kit for TLV320AIC3256 miniDSP audio codec. The evaluation module is a USB audio device with programmable inputs and outputs, effects, and extensive routing capabilities. The evaluation module has two stereo analog input connectors (Line In and Mic In) and two stereo analog output connectors (line out and headphone out) that are routed to the TLV320AIC3256. Digital audio as well as control data communicated between the personal computer and the evaluation module are interpreted by the TAS1020B USB Streaming Controller. Control data is communicated to the TLV320AIC3256 via the I2C or SPI protocols, audio data is communicated via the I2S protocol. An onboard 64KB EEPROM is capable of storing TLV320AIC3256 commands (scripts) as well as the TAS1020B firmware. Two pushbuttons are provided to cycle between scripts along with two LEDs that provide the user feedback regarding the script that is currently loaded.
