Description
VS1011e is a single-chip MPEG audio (MP3)
decoder IC. It contains a high-performance,
low-power DSP core VS_DSP
4
, working mem-
ory, 5 KiB instruction RAM and 0.5 KiB data
RAM for user applications, serial control and
input data interfaces, 4 general purpose I/O
pins, as well as a high-quality variable-sample-
rate stereo DAC, followed by an earphone am-
plifier and a common buffer.
VS1011e 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 basic decod-
ing, it is possible to add application specific
features, like DSP effects, to the user RAM
memory.
VS1011e can boot directly from SPI EEPROM
to run standalone applications without a sep-
arate microcontroller.
