VL716 - USB3.1 to SATA 6Gb/s Bridge Controller for Type-C Connector

Description


 
VIA Lab’s VL716 is a high performance, low power single chip USB 3.1 to SATA 6Gb/s bridge controller with USB type-C connector support designed for new generation external storage devices that connecting Hard Disk Drive (HDD), Solid-State Drive (SSD), and Optical Disc Drive (ODD). Its integrated in-house USB 3.1 PHY enables VL716 to run in USB SuperSpeedPlus, Super-Speed, High-Speed, and Full-Speed modes. Supporting USB mass storage class Bulk-Only Transport (BOT), VL716 based devices can work on Windows 8, Windows 7, Vista, XP, Mac OS X and various Linux kernels without additional driver. Besides Bulk-Only Transport, VL716 also support USB Attached SCSI Protocol (UASP) that allowing mass storage command queuing and out of order data transfers to further enhance read/write performance. Its integrated in-house SATA 6Gb/s host controller can work with all SATA based storage devices and can connect at SATA 6Gb/s, SATA 3Gb/s, or SATA 1.5Gb/s automatically. Built-in CC1/CC2 cable orientation detection circuits and two sets of SuperSpeed USB signal pins can support USB type-C receptacle natively to enable plug flipping feature without any extra cost.

Built-in all required linear and switching voltage regulators, highly integrated VL716 work perfectly with single power input from USB 5V bus power to save customer BOM cost. 6 GPIO pins are available for push button, operation LEDs, device power down control, and other special usage. The SPI interface can support external flash for firmware upgrades or additional software enhancements. VL716 is available in QFN 48L (6x6x0.85 mm) green packages to fit small form-factor design supporting USB type-C receptacle.
