MP3 and MIDI Codec - VS1053B

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.

MP3 and MIDI Codec - VS1053B Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    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.

  • Member #585 / about 12 years ago / 1

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

  • Virgil_Disgr4ce / about 12 years ago / 1

    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?

  • IgnacioV / about 12 years ago / 1

    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.

    • Sleahey / about 12 years ago / 1

      And that 1063 is an awesome looking chip... extremely capable...

  • simbre / about 12 years ago / 1

    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

    hi - what about the breakout board for VS1053B ? thx

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

    • bsharitt / about 15 years ago / 2

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

      • tim80 / about 15 years ago / 1

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

  • tim80 / about 15 years ago / 1

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