Microchip announces its third-generation USB3 Controller Hubs (UCH3s): the four-member USB553XB-5000 family is SuperSpeed Logo Certified by the USB Implementers Forum and is the world’s first to integrate OTP Flash configuration memory. This UCH3 family is also the industry’s most flexible, as it includes a seven-port hybrid version with a certified four-port USB3 hub and three additional USB2 lanes. The remaining three family members feature two-, three- and four-port USB3 hubs, respectively, providing a broad migration path for the designers of PCs, peripherals, computing platforms, storage solutions, networking and consumer devices, set-top boxes, docking stations and monitors.
The designers of computing and peripheral platforms are rapidly adopting the USB3 standard for its increased bandwidth of 5 Gbps and higher-power charging ports. To address market pricing, delivery and differentiation pressures, designers need USB3 controller hubs with a high degree of flexibility and integration. Microchip’s new UCH3 family lowers system costs and speeds development by integrating programmable memory that allows OEMs to quickly customise their products and ensure operating-system compatibility, without the added cost, complexity and board space of off-chip memory.
