The STA015 is a fully integrated high flexibility MPEG Layer III Audio Decoder, capable of decoding Layer III compressed elementary streams, as specified in MPEG 1 and MPEG 2 ISO standards. The device decodes also elementary streams compressed by using low sampling rates, as specified by MPEG 2.5. STA015 receives the input data through a Serial input Interface. The decoded signal is a stereo, mono, or dual channel digital output that can be sent directly to a D/A converter, by the PCM Output Interface. This interface is software programmable to adapt the STA015 digital output to the most common DACs architectures used on the market.

Evaluation Boards And Tools	STA015EVB	TThe STA015 Evaluation Board (STA015EVB) is useful to perform functional verification of the device operation. ST provides a dedicated software for STA015T. STA015T can be used to emulate, via the PC parallel port, the I2C protocol in order to control all the device operations, and to send an audio bitstream: any kind of layer III MP3 file can be transmitted.
