FEATURES
DESCRIPTION
● Encoders:● Decoders: MP3 (MPEG 1 & 2 audio layer III (CBR +VBR +ABR)); MP2 (layer II) (optional); MPEG4 / 2 AAC-LC(+PNS), HE-AAC v2 (Level 3) (SBR + PS); Ogg Vorbis; FLAC; WMA 4.0/4.1/7/8/9 all profiles (5-384 kbps); WAV (PCM, IMA ADPCM, G.711 µ-law/Alaw, G.722 ADPCM)
● Full Duplex Codecs with optional AEC: VS1063a contains a high-performance, proprietary low-power DSP core VS_DSP4, ROM memories, 16 KiB instruction RAM and up to 80 KiB data RAM for user applications running simultaneously with any built-in decoder, serial control and input data interfaces, up to 12 general purpose I/O pins, a UART, as well as a high-quality stereo ADC, and a variablesample-rate stereo DAC, followed by an earphone amplifier and a common voltage buffer. PCM; G.711 (µ-law, A-law); G.722 ADPCM; IMA ADPCM
● Streaming support
● Up to 96 KiB RAM for user code / data 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.
