Overview
The TUSB7320RKMT is a USB 3.0-compliant xHCI (eXtensible Host Controller Interface) host controller produced by Texas Instruments. This integrated circuit is designed to support high-speed USB 3.0 connections, along with backward compatibility for USB 2.0 and 1.1 devices. The TUSB7320RKMT is part of the TUSB73x0 family, which includes both the TUSB7320 and TUSB7340 models, differing primarily in the number of downstream ports supported.
This component is particularly suited for applications requiring robust and reliable USB connectivity, such as in server systems, high-performance computing, and storage area networks.
