Overview
The TUSB9261IPVP, produced by Texas Instruments, is an ARM Cortex M3 microcontroller-based USB 3.0 to SATA bridge. This component provides the necessary hardware and firmware to implement a USB attached SCSI protocol (UASP)-compliant mass storage device. It is designed to bridge 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. The device supports both UASP and USB Mass Storage Class Bulk-Only Transport (BOT) interfaces, along with USB Human Interface Device (HID) functionality.
