VLSI Solution Unveils VS1005 All-In-One MP3 Audio System-on-a-Chip

VLSI Solution introduced the VS1005 all-in-one MP3 audio System-on-a-Chip. The VS1005 SoC includes controllers for high-speed USB host/slave, SD card, parallel NAND flash, SPI, Ethernet, S/PDIF, I2S master/slave and UART. The VLSI VS1005 chip is ideal for portable audio devices, docking stations, and portable recorder applications. Engineering samples of the VS1005 are expected to be available in June 2012. Mass production devices are expected in October 2012. The VS1005 System-on-a-Chip is offered in LFGA-88 10x10x0.9 RoHS compatible package.

The audio signal paths of VS1005 SoC are very flexible. Digital audio inputs and outputs can be independent of analog inputs and outputs. Digital interfaces like S/PDIF allow easy and high-quality digital connectivity to home stereo systems. A digital sample rate converter allows for inputs and outputs with different sample rates.
