The Microchip USB2640I-HZH-02: A Robust Hi-Speed Hub Controller for Modern Connectivity

In the realm of universal serial bus (USB) technology, the demand for reliable and high-performance hub controllers is paramount. The Microchip USB2640I-HZH-02 stands out as a highly integrated Hi-Speed Hub Controller designed to meet the rigorous requirements of contemporary embedded systems and consumer electronics. This compact integrated circuit serves as a critical component for expanding a single USB host port into multiple downstream ports, enabling seamless connectivity for a multitude of peripherals.

Engineered for versatility, this hub controller complies with USB 2.0 specifications, supporting data transfer rates up to 480 Mbps on its Hi-Speed downstream ports. Its architecture ensures full backward compatibility with older Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) devices, making it an ideal solution for systems that must interface with a wide array of legacy and modern USB gadgets. The device incorporates a 4-port hub configuration, providing ample connectivity in a single, efficient package.

A key feature of the USB2640I-HZH-02 is its advanced level of integration. It includes an on-chip 5V to 3.3V and 1.8V voltage regulator, significantly reducing the need for external power management components and simplifying overall system design. This not only minimizes the bill of materials (BOM) but also conserves valuable board space, which is crucial for compact product designs. Furthermore, the hub supports both individual and ganged power switching and port over-current protection, giving designers flexibility in managing power distribution and enhancing the safety and reliability of the end product.

The controller also boasts robust electrostatic discharge (ESD) protection on all USB ports, exceeding the requirements set by the USB-IF. This inherent ruggedness ensures greater long-term reliability in electrically noisy environments, reducing the likelihood of field failures. Its industrial temperature rating (-40°C to +85°C) further underscores its suitability for a broad spectrum of applications, from commercial computing to more demanding industrial and automotive environments.

For developers, Microchip provides comprehensive support through proven reference designs and a mature software stack, which drastically accelerates time-to-market. The USB2640I-HZH-02 is offered in a compact, halogen-free 48-pin QFN package, aligning with modern environmental standards and manufacturing processes.

ICGOODFIND: The Microchip USB2640I-HZH-02 Hi-Speed Hub Controller is a highly integrated, robust, and flexible solution for expanding USB connectivity. Its combination of compliance, built-in power management, and strong protection features makes it an excellent choice for designers aiming to create reliable and efficient products in today's connected world.
