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.
