New Original VS1053B VS1053 MP3/WAV/OGG/MIDI PLAYER IC Chip

VS1053b 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 RAM and 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-samplerate 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 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.

Optional factory-programmable unique chip ID provides basis for digital rights management or unit identification features.
