TUSB7320IRKMT

Controllers Overview

The TUSB7320IRKMT is a SuperSpeed USB 3.0 Extensible Host Controller (xHCI) manufactured by Texas Instruments. It provides two independent USB 3.0 host ports with data transfer rates up to 5 Gbps, compliant with the USB 3.0 specification. The device interfaces with a host processor via a PCI Express Gen 1 x1 link and supports legacy USB 2.0 devices through integrated high-speed hubs. Key electrical parameters include a maximum data transmission rate of 625 MBps, a maximum clock frequency of 50 MHz for the interface, and operation within a temperature range of -40°C to +85°C. It requires a 3.3V supply and is housed in a 100-pin QFN package.

Controllers Feature Summary

• Supports SuperSpeed USB 3.0 and High-Speed USB 2.0 protocols
• Integrates dual-port architecture with internal hub functionality
• Connects to host systems via PCI Express Gen 1 x1 interface

Controllers Applications

• Desktop and notebook computer mainboards
• Peripheral expansion cards and docking stations
• Industrial embedded systems requiring USB 3.0 connectivity

Controllers Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status and lead-free designation against current manufacturer documentation. Ensure the component matches the specific pinout and thermal pad requirements for the target PCB layout.

Controllers Selection Notes

Select this controller for designs requiring two native USB 3.0 ports connected via PCIe. Compare against the four-port TUSB7340 variant if higher port density is needed. Verify that the host system supports the required PCIe Gen 1 x1 bandwidth and power delivery specifications for reliable operation.

Controllers Part Context

This component belongs to the TUSB73x0 family of USB 3.0 host controllers from Texas Instruments. It serves as a bridge between the PCIe bus and USB peripherals, enabling high-speed data transfer capabilities in modern computing platforms and industrial control applications.

Controllers Replacement Considerations

The TUSB7340IRKMR is a verified four-port alternative within the same family. Check datasheet compatibility for pin-to-pin substitution if additional ports are required without changing the board layout significantly.
