TUSB9261PVP

Specialized Overview

The TUSB9261PVP is a USB 3.0 to SATA bridge controller manufactured by Texas Instruments, designed for high-speed data transfer between USB 3.0 hosts and SATA storage devices. It supports SuperSpeed (5 Gbps), High-Speed (480 Mbps), and Full-Speed (12 Mbps) USB protocols alongside SATA Gen1 (1.5 Gbps) and Gen2 (3.0 Gbps) interfaces. The device integrates an ARM Cortex-M3 microcontroller for custom application execution and firmware management via SPI flash. Key electrical parameters include a maximum data transfer rate of 384 MBps and a maximum clock frequency of 40 MHz. It operates within a commercial temperature range of 0°C to 70°C and utilizes a 64-pin HTQFP package compliant with RoHS standards.

Specialized Feature Summary

• Supports USB Attached SCSI Protocol (UASP) for improved throughput compared to traditional Bulk-Only Transport modes.
• Integrates an ARM Cortex-M3 core allowing for custom firmware loading and peripheral control via GPIO and SPI interfaces.
• Includes adaptive equalization in the integrated transceiver to enhance signal integrity and jitter tolerance at high speeds.
• Features built-in spread-spectrum clock generation to reduce electromagnetic interference without requiring external complex circuitry.

Specialized Applications

• External hard disk drive (HDD) enclosures
• Solid-state drive (SSD) docking stations
• Optical disc drives (DVD/CD) with USB connectivity
• Portable media players utilizing HDD storage

Specialized Procurement Notes

Verify the specific suffix PVP corresponds to the HTQFP-64 package and commercial temperature grade during sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure compatibility with required SPI flash memory for firmware programming before integration into production designs.

Specialized Selection Notes

Select this component when designing systems requiring direct conversion from USB 3.0 host ports to SATA storage interfaces. Consider the integrated MCU capabilities if custom HID or boot functionality is required. Evaluate thermal performance within the 0°C to 70°C operating range for the target enclosure environment.
