The TUSB9260 is an ARM cortex M3 microcontroller based USB 3.0 to serial ATA bridge. It provides the necessary hardware and firmware to implement a USB attached SCSI protocol (UASP) compliant mass storage device suitable for bridging hard disk drives (HDD), solid state disk drives (SSD), optical drives and other compatible SATA 1.5-Gbps or SATA 3.0-Gbps devices to a USB 3.0 bus. In addition to UASP support, the firmware implements the mass storage class bulk-only transport (BOT), and USB human interface device (HID) interfaces.
