VL701 Low-Power Super-Speed USB to SATA 3Gb/s Bridge ControllerVL701 System OverviewVIA Lab’s VL701 is a high performance, low power single chip USB 3.0 to SATA 3Gb/s bridge controllerdesigned for new generation external storage devices that connecting Hard Disk Drive (HDD), Solid-StateDrive (SSD), and Optical Disc Drive (ODD). Its integrated in-house USB PHY enables VL701 to run in USBSuper-Speed, High-Speed, and Full-Speed modes. Supporting USB mass storage class Bulk-OnlyTransport (BOT), VL701 based devices can work on Windows 7, Vista, XP, 2003/2000/ME, Mac OS X andvarious Linux kernels without additional driver. Besides Bulk-Only Transport, VL701 also support USBAttached SCSI Protocol (UASP) that allowing mass storage command queuing and out of order datatransfers to further enhance read/write performance. Its integrated in-house SATA 3Gb/s host controllercan work with all SATA based storage devices and can connect at either SATA 3Gb/s or 1.5Gb/sautomatically.Built-in all required linear and switching voltage regulators, highly integrated VL701 work perfectly withsingle power input from USB 5V bus power to save customer BOM cost. 11 GPIO pins are available forpush button, operation LEDs, driverless capacity LEDs, device power down control, and other specialusage. The SPI interface can support external flash for firmware upgrades or additional softwareenhancements. VL701 is available in LQFP 64L (7x7x1.4 mm), QFN 48L (6x6x0.85 mm), and QFN 44L(6x5x0.85 mm) green packages to fit small form-factor design.Figure 1 – VL701 Block Diagram-5-
