VLSI: VS1053B-L (LQFP48)

Ogg Vorbis / MP3 / AAC / WMA / FLAC / MIDI Audio Codec

VS1053 is an Ogg Vorbis / MP3 / AAC / WMA / FLAC / MIDI audio decoder, 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 kB instruction RAM and up to 80 kB data RAM for user applications, 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 and stereo DAC, followed by an earphone amplifier and a common voltage buffer.
VS1053 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 oversampling, 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.
Users can write their own user interface or signal processing code for the VS1053 using VSIDE (VLSI Solution’s Integrated Development Environment).
