The Microchip USB2517I-JZX-TR: A Robust 7-Port USB 2.0 Hi-Speed Hub Controller

In the realm of modern connectivity, the demand for efficient and reliable USB expansion solutions remains high. The Microchip USB2517I-JZX-TR stands out as a highly integrated 7-port USB 2.0 Hi-Speed Hub Controller designed to meet these demands with exceptional performance and flexibility. This hub controller enables the seamless addition of multiple USB ports to a wide array of systems, from industrial equipment and embedded systems to consumer peripherals and desktop computers.

A key strength of the USB2517I-JZX-TR is its compliance with the USB 2.0 specification, supporting data transfer rates of up to 480 Mbps on each downstream port. This ensures that connected devices operate at their full Hi-Speed potential. The controller incorporates a highly advanced multi-transaction translator (MTT) architecture, which significantly enhances overall system performance. This architecture allows multiple simultaneous transactions to occur across all ports, drastically reducing bottlenecks and ensuring smooth data flow even when multiple high-bandwidth devices are in use.

The device is engineered for robust operation and design simplicity. It features fully integrated USB termination and pull-up/pull-down resistors, which minimize external component count and simplify PCB layout. This integration not only reduces the total bill of materials (BOM) but also accelerates time-to-market for product developers. Furthermore, its support for individual or ganged power switching and over-current detection for each downstream port provides system designers with precise control over power management, enhancing the safety and reliability of the end application.

The USB2517I-JZX-TR is offered in a compact 36-pin QFN package, making it suitable for space-constrained designs. Its industrial temperature range support ensures reliable operation in challenging environments.

ICGOODFIND: The Microchip USB2517I-JZX-TR is an industry-proven solution for scalable USB connectivity, offering a blend of high performance, design flexibility, and robust integration that is critical for modern electronic designs.
