9.1 Main Features

VS1063a is based on a proprietary digital signal processor, VS_DSP. It contains all the code

and data memory needed for Ogg Vorbis, MP3, AAC, WMA, FLAC and WAV PCM + ADPCM

audio decoding together with serial interfaces, a multirate stereo audio DAC and analog output

ampliﬁers and ﬁlters.

Also MP3, OGG, PCM, ADPCM, µ-law, A-law and G.722 audio encoding is supported using a

microphone ampliﬁer and/or line-level inputs and a stereo A/D converter.

For streaming applications there exists a codec mode that supports full-duplex operation using

PCM, ADPCM, µ-law, A-law or G.722 formats. The formats and samplerates don’t have to be

the same in both directions.

A UART is provided for debugging purposes to connect with VLSI Solution’s Integrated Devel-

opments Environment VSIDE.
