    VS1003b VS1003 VS1003 - MP3/WMA AUDIO CODEC Features Description or line input • Decodes MPEG 1 & 2 audio layer III (CBR +VBR +ABR); WMA 4.0/4.1/7/8/9 all pro- files (5-384kbit/s); WAV (PCM + IMA AD- PCM); General MIDI / SP-MIDI files • Encodes IMA ADPCM from microphone • Streaming support for MP3 and WAV • Bass and treble controls • Operates with a single 12..13 MHz clock • Internal PLL clock multiplier • Low-power operation • High-quality on-chip stereo DAC with no • Stereo earphone driver capable of driving a • Separate operating voltages for analog, dig- • 5.5 KiB On-chip RAM for user code / data • Serial control and data interfaces • Can be used as a slave co-processor • SPI flash boot for special applications • UART for debugging purposes • New functions may be added with software phase error between channels 30Ω load ital and I/O VS1003 is a single-chip MP3/WMA/MIDI audio decoder and ADPCM encoder. It contains a high- performance, proprietary low-power DSP proces- sor core VS DSP4, working data memory, 5 KiB instruction RAM and 0.5 KiB data RAM for user applications, serial control and input data inter- faces, 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 amplifier and a common buffer. VS1003 receives its input bitstream through a se- rial 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 con- trolled 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. and 4 GPIO pins Version 1.04, 2009-02-03 1 VLSISolutionyInstruction RAMInstruction ROMStereo DACMonoADCLRUARTSerialData/ControlInterfaceStereo Ear−phone DriverDREQSOSISCLKXCSRXTXaudiooutputX ROMX RAMY ROMY RAM4GPIOGPIOVSDSP4XDCSVS1003MIC AMP ClockmultiplierMUXlineaudiomicaudio
