VS1103b is a single-chip MIDI/ADPCM/WAV audio decoder and ADPCM encoder that can handle up to three simultaneous audio streams. It can also act as a MIDI synthesizer. VS1103B contains a high-performance, proprietary low-power DSP processor core VS DSP4, working data memory, 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, an UART, as well as a high-quality variable-sample-rate mono ADC and stereo DAC, followed by an earphone amp and a common buffer.
VS1103b receives its input bitstreams through serial input buses, which it listens to as a system slave. The input streams are decoded and passed through digital volume controls to an 18-bit oversampling, multi-bit, sigma-delta DAC. Decoding is controlled via a serial control bus. In addition to basic decoding, it is possible to add application specific features, like DSP effects, to user RAM memory.
Available in a LQFP-48 pin 7x7x1.4mm package.
Features:
Mixes three audio sources: General MIDI 1+ / SP-MIDI, WAV (PCM + IMA ADPCM), Microphone or line input
