PRELIMINARY VS1063a Prog. Guide VS1063a Programmer’s Guide MP3/OGG/AAC/WMA/FLAC/ G.711/G.722 AUDIO CODEC CIRCUIT Key Features Description Encoders: VS1063a is an easy-to-use, versatile encoder, MP3; Ogg Vorbis; PCM; IMA ADPCM; decoder and codec for a multitude of audio G.711 (µ-law, A-law); G.722 ADPCM Decoders: formats. MP3 (MPEG 1 & 2 audio layer III (CBR +VBR +ABR)); VS1063a contains a high-performance, proprietary low-power DSP core VS_DSP4, ROM MP2 (layer II) (optional); memories, 16 KiB instruction RAM and upto MPEG4 / 2 AAC-LC(+PNS), 80 KiB data RAM for user applications run- HE-AAC v2 (Level 3) (SBR + PS); ning simultaneously with any built-in decoder, Ogg Vorbis; FLAC; serial control and input data interfaces, upto WMA 4.0/4.1/7/8/9 all profiles (5-384 kbps); 12 general purpose I/O pins, a UART, as well WAV (PCM, IMA ADPCM, G.711 µ-law/A- as a high-quality variable-sample-rate stereo law, G.722 ADPCM) DAC and a stereo ADC, followed by an ear- Full Duplex Codecs: phone amplifier and a common voltage buffer. PCM; G.711 (µ-law, A-law); G.722 ADPCM Streaming support Upto 96 KiB RAM for user code and data Unique ID for user code protection Quiet power-on and power-off VS1063a can act both as an “MP3 decoder IC” or “MP3 encoder IC” slave in a system with a microcontroller, or as a stand-alone circuit that boots from external SPI memory. I2S interface for external DAC Serial control and data interfaces Can be used either as a ...
