VS1011e is a single-chip MPEG audio decoder.The chip contains a high-performance, low-powerDSP processor core VS DSP4, working memory,5 KiB instrucTIon RAM and 0.5 KiB data RAMfor user applicaTIons, serial control and input datainterfaces, 4 general purpose I/O pins, as well asa high-quality variable-sample-rate stereo DAC,followed by an earphone amplifier and a commonbuffer.VS1011e receives its input bitstream through a serialinput bus, which it listens to as a system slave.The input stream is decoded and passed through adigital volume control to an 18-bit oversampling,mulTI-bit, sigma-delta DAC. The decoding is controlledvia a serial control bus. In addiTIon to basicdecoding, it is possible to add application specificfeatures, like DSP effects, to the user RAM memory.
