Description: VS1053b from VLSI is a single-chip Ogg Vorbis/MP3/AAC/WMA/MIDI audio decoder and an IMA ADPCM and user-loadable Ogg Vorbis encoder. It contains a high-performance, proprietary low-power DSP processor core VS DSP4, working data memory, 16 KiB instruction RAMand 0.5+ KiB data RAM for user applications running simultaneously with any built-in decoder, serial control and input data interfaces, upto 8 general purpose I/O pins, an UART, as well as a high-quality variable-sample rate stereo ADC (mic, line, line + mic or 2×line) and stereo DAC, followed by an earphone amplifier and a common voltage buffer.

VS1053b receives its input bitstream through a serial input bus, which it listens to as a system slave. The input stream is decoded and passed through a digital volume control to an 18-bit over-sampling, multi-bit, sigma-delta DAC. The decoding is controlled via a serial control bus. In addition to the basic decoding, it is possible to add application specific features, like DSP effects, to
the user RAM memory.

Available in a LQFP-48 pin 7x7x1.4mm package.


  • Decodes multiple formats: Ogg Vorbis, MPEG 1 & 2 audio layer III (CBR+VBR+ABR), layers I & II optional, MPEG4 / 2 AAC-LC(+PNS), HE-AAC v2 (Level 3) (SBR + PS), WMA4.0/4.1/7/8/9 all profiles (5-384 kbps), WAV (PCM + IMA ADPCM), General MIDI 1 / SP-MIDI format 0

  • Hi. I would like to use a fm tuner with this chip (such as Si4703, ref sparkfun BOB-11083). I want to use the stereo line in of the VS1053B. My final product would be a mp3 player with a fm tuner. The VLSI would amplify the audio signal from the tuner. I would like to connect the antenna to the earphone connector. On the tuner apllication note, there is a simple matching circuit (LC) to link the antenna input and the earphone connector. But how would this react with the VLSI GBUF output ? Do I have to use a coupler or something ? Thanks for you help or remarks ;) Serge

  • can these run with an arduino giving it the comands, i’m thinking diy mp3 player.

  • These are available on ebay for $6, so why is the price here so outrageous ?.

  • Anyone have any idea if this chip (or one like it) would be able to slow down and speed up the playback of a file? No pitch correction, just resampling?

  • Are there any plans to make the VS1063 available?

    Upgraders will be happy to know that from a hardware point of view VS1063 is a drop-in replacement for VS1053.

  • Hi, can anyone please tell me the latency of the chip from getting the command, until it plays wav/flac/ogg files from flash?
    Couldn’t find that in the data sheet.
    greetings, Simon

  • Please restock these puppies !!!

  • hi - what about the breakout board for VS1053B ? thx

  • There should be a breakout board for this released within a week.

    • I hope the breakout board comes soon. My unsteady hands are not fans of surface mount.

      • Me too.
        I have an order ready to go, just needs a VS1053 breakout board added to it.

  • Will you be making a breakout board for this IC like the one for the VS1002?
