Cypress offers a complete reference design for developing a fixed function 4-port USB Hub that is production ready and USB compliant. This single chip design is based on the CY7C65640-LFC, offering a space saving and cost effective package. Because it is USB compliant it is fully backward compatible with USB systems. It provides for up to four downstream ports, and supports High Speed, Full Speed and Low Speed traffic. No firmware development is required for this design, thereby reducing design risk and time-to-market. Our Reference Design Kits include a fully functional demonstration board as well as all of the design materials you will need to expedite the development of your custom product.
