Microchip USB2412-DZK: A 2-Port USB 2.0 Hi-Speed Hub Controller for Embedded Systems

The increasing complexity of modern embedded systems demands robust and flexible connectivity solutions. The Microchip USB2412-DZK stands out as a highly integrated, low-power, and compact 2-port USB 2.0 Hi-Speed hub controller designed specifically to meet these demands. This device serves as a critical component, enabling the expansion of a single USB host port into two downstream ports, thereby enhancing the connectivity capabilities of a wide array of embedded applications.

Engineered for performance and efficiency, the USB2412-DZK supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates, ensuring full backward compatibility with the vast ecosystem of USB devices. Its internal architecture features a multi-transaction translator (Multi-TT) design. This is a crucial differentiator, as it allows each downstream port to operate with its own dedicated translator. This significantly improves overall bandwidth efficiency and reduces latency, especially when multiple full-speed or low-speed devices are connected simultaneously, preventing a single slow device from bottlenecking the entire hub.

A key advantage of the USB2412-DZK is its focus on simplifying design-in and reducing both system cost and board space. The hub requires a minimal number of external components, primarily needing only a single 24 MHz crystal and decoupling capacitors to become fully operational. It is available in a space-efficient 32-pin QFN (5x5 mm) package, making it an ideal choice for space-constrained applications. Furthermore, its advanced power management features, including support for individual or ganged power switching and over-current detection for each downstream port, provide designers with greater control over power distribution and system safety.

The versatility of the USB2412-DZK makes it suitable for a broad spectrum of embedded markets. It is commonly integrated into products such as PC motherboards and monitors, industrial automation equipment, set-top boxes, printers, and various IoT gateways. Its ability to provide stable and reliable USB expansion is fundamental in systems where peripheral connectivity is paramount.

In summary, the Microchip USB2412-DZK provides a robust, feature-rich, and cost-effective solution for adding USB hub functionality to embedded designs.

ICGOODFIND: The Microchip USB2412-DZK is a highly integrated 2-port hub controller that excels in providing superior bandwidth management with its Multi-TT architecture, low power operation, and a minimal external component count. Its small form factor and comprehensive feature set make it an exceptional choice for developers seeking reliable USB expansion in space- and power-conscious embedded systems.
