Product Description
VS1053B-L QFP-48 Voltage Regulator IC VLSI LQFP-48
Description
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.
