VS1011 receives its input bitstream through a serial input bus. The input stream is decoded and passed to an 18-bit oversampling, multi-bit, sigma-delta DAC and earphone driver. The control commands of the device are transferred via the same serial bus as the data. In addition to basic MP3 decoding VS1011 can play PCM and WAV files. Optionally also MP1 and MP2 decoding can be enabled (check licensing issues). 5.5 kB RAM has been reserved for user application specific features, like DSP effects.
