Description
VS1053b is an Ogg Vorbis/MP3/AAC/WMA/
FLAC/WAVMIDI audio decoder as well as an
PCM/IMA ADPCM/Ogg Vorbis encoder on a
single chip. It contains a high-performance,
proprietary low-power DSP processor core
VS_DSP4, data memory, 16 KiB instruction
RAM and 0.5+ KiB data RAM for user applications
running simultaneously with any builtin
decoder, serial control and input data interfaces,
up to 8 general purpose I/O pins,
an UART, as well as a high-quality variablesample-
rate stereo ADC (mic, line, line + mic
or 2line) 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, sigmadelta
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.
