Automotive 2nd Generation SuperSpeed USB 3.0 to Serial ATA Bridge - TUSB9261-Q1

TUSB9261-Q1 (ACTIVE)

Automotive 2nd Generation SuperSpeed USB 3.0 to Serial ATA Bridge

 

Description

The TUSB9261-Q1 is an ARM cortex M3 microcontroller based Universal Serial Bus (USB) 3.0 to Serial ATA (SATA) bridge. It provides the necessary hardware and firmware to implement a USB Attached SCSI Protocol (UASP) compliant mass storage device suitable for bridging SATA compatible hard disk drives (HDD) and solid state disk drives (SSD) to a USB 3.0 bus. The firmware also implements the mass storage class bulk-only transport (BOT) for bridging optical drives and other compatible SATA devices to the USB bus. In addition to UASP and BOT support,a USB human interface device (HID) interfaces is supported for control of the general purpose input/ouput (GPIO). The SATA interface supports gen1 (1.5-Gbps) and gen2 (3.0-Gbps) for cable lengths up to 2 meters.

The device is available in a 64-pin HTQFP package and is designed for operation over the industrial temperature range of –40°C to 85°C.
