MP3 Codec IC - VS1011E-L

MP3 decoding is now even easier! This is the popular VS1011 single-chip MP3 audio decoder from VLSI is a LQFP package! It contains a high-performance, low-power DSP processor core VS DSP4, working data memory, 5.5kBytes of program or data RAM for for user applications, serial control and input data interfaces, and a high-quality oversampling variable-sample-rate stereo DAC.

VS1011 receives its input bitstream through a serial input bus. The input stream is decoded and passed to an 18-bit oversampling, multi-bit, sigma-delta DAC and earphone driver. The control commands of the device are transferred via the same serial bus as the data. In addition to basic MP3 decoding VS1011 can play PCM and WAV files. Optionally also MP1 and MP2 decoding can be enabled (check licensing issues). 5.5 kB RAM has been reserved for user application specific features, like DSP effects.

Available in a LQFP-48 pin package.

MP3 Codec IC - VS1011E-L 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.

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.
