VL716是一款高性能、低功耗的单芯片USB 3.1到SATA 6Gb/s桥接控制器，支持USB type-C连接器，用于连接硬盘驱动器(HDD)、固态驱动器(SSD)和光盘驱动器(ODD)的新一代外部存储设备。其集成的内部USB 3.1 PHY使VL716运行在USB SuperSpeedPlus，超高速，高速和全速模式。支持USB大容量存储类批量传输(BOT)，基于VL716的设备可以工作在Windows 8, Windows 7, Vista, XP, Mac OS X和各种Linux内核没有额外的驱动程序。除了大容量传输外，VL716还支持UASP (USB Attached SCSI Protocol)协议，允许大容量存储命令队列和无序数据传输，进一步提高读写性能。内置SATA 6Gb/s主控制器，可与所有基于SATA的存储设备兼容，可自动连接SATA 6Gb/s、SATA 3Gb/s或SATA 1.5Gb/s。内置CC1/CC2电缆方向检测电路和两套SuperSpeed USB信号引脚，可支持USB - c型插座，无需任何额外成本即可实现插拔功能。
内置所有所需的线性和开关稳压器，高度集成的VL716与USB 5V总线电源的单电源输入完美工作，节省客户的BOM成本。6 GPIO引脚可用于按钮，操作led，设备下电控制，和其他特殊用途。SPI接口可以支持用于固件升级或附加软件增强的外部flash。VL716可采用qfn48l (6x6x0.85 mm)绿色封装，适合小型形状因素设计，支持USB - c型插座。
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.
