Tampere, Finland; February sixth 2012 – VLSI answer announces VS1005 SoC, a tremendously integrated all-in-one chip for audio processing applications. The VS1005 gadget-on-a-Chip consists of an in depth set of peripheral interfaces. blanketed are controllers for hi-pace USB host/slave, SD card, parallel NAND flash, SPI, Ethernet, S/PDIF, I2S master/slave and UART. VS1005 also carries 24-bit ADC’s and DAC’s, headphone and microphone amplifiers, linear regulators, a true-time clock, and an FM tuner with RDS. controlled through a DSP, all these facets enable for remarkable flexibility in growing hello-Fi stereo audio products.
The points of VS1005 are primarily suited for portable audio devices, docking stations, and transportable recorder applications. To construct a state-of-the-paintings personal track participant or recorder just three extra circuits in addition to the VS1005 SoC are necessary (a NAND flash, an axis accelerometer, and an influence administration device).
The audio signal paths of VS1005 SoC are very flexible. Digital audio inputs and outputs can be impartial of analog inputs and outputs. Digital interfaces like S/PDIF enable convenient and terrific digital connectivity to domestic stereo techniques. A digital sample price converter enables for inputs and outputs with different pattern quotes.
The hello-velocity USB host function is helpful in techniques that require audio playback potential from external media such as USB reminiscence sticks or drives, opening up many new applications in AV receivers and radio players. USB slave mode is additionally supported.
The Ethernet interface gives web streaming capability over wired lines. I2S extends digital connectivity with other ICs. The RTC and battery backed registers provide alarm capabilities as well as very low energy – low velocity modes for the DSP.
The VS1005 SoC takes a new approach in software building when compared to VLSI’s earlier products. The multitasking working system VSOS and the object code library MegaLib offer features that can be utilized with VLSI answer’s integrated construction ambiance VSIDE. This combination makes writing functions to VS1005’s 256 KiB RAM reminiscence a simple and intuitive system. To additional lengthen VS1005’s usability, code can be loaded dynamically from any non-risky reminiscence, including VS1005’s non-compulsory internal 1024 KiB flash reminiscence. The inside flash reminiscence may also be covered, making it possible for builders and third parties to protect their code.
The MegaLib library comprises all VLSI solution’s present codecs: MP3 and Ogg Vorbis encoders, MP2, MP3, WMA, OGG, LC-AAC, HC-AAC, FLAC, IMA and WAV PCM decoders, and other capabilities: FM together with RDS, file I/O, device drivers, utility loading, multitasking, graphical interface features, audio processing, and so on.
VS1005 SoC is obtainable in LFGA-88 RoHS appropriate equipment.
greater assistance is obtainable at The VS1005 Datasheet may be obtainable in late February 2012. Two other documents, The VS1005 Hardware e book and The VS1005 Programmer’s book, should be purchasable in April 2012.
VS1005 engineering samples are anticipated to be accessible in June 2012, followed through mass creation devices in October 2012.
