Description
VS1011e is a single-chip MPEG audio (MP3)
decoder IC. The circuit contains a high-performance,
low-power DSP processor core VS_DSP4, work-
ing memory, 5 KiB instruction RAM and 0.5
KiB data RAM for user applications, serial con-
trol and input data interfaces, 4 general pur-
pose I/O pins, as well as a high-quality variable-
sample-rate stereo DAC, followed by an ear-
phone amplifier 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.
