3 Description

The TUSB9261 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 BOT and USB HID interfaces.
