VS1001k is a single-chip solution for an MPEG layer 3 audio decoder. The chip contains a highperformance low-power DSP processor (VS DSP),
working memory, 4 KiB program RAM and 0.5
KiB data RAM for user applications, serial control
and input data interfaces, and a high-quality
oversampling variable-sample-rate stereo DAC, followed
by an earphone amplifier and a ground buffer.
VS1001k 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 analog/digital hybrid 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.
