The CYUSB3314-88LTXIT from Infineon (previously Cypress Semiconductors) is a high-speed, multi-port USB 3.0 hub controller that supports USB 2.0 and USB 3.0 connectivity simultaneously. Part of the Cypress HX3 family, it enables low-power, high-bandwidth USB expansion for consumer electronics, embedded systems, and industrial applications.
This quad-port SuperSpeed hub supports Low-Speed, Full-Speed, High-Speed, and SuperSpeed (5 Gbps) USB operations in a single compact 88-pin QFN package. It integrates a USB 3.0 hub, USB 2.0 hub, configuration options, power management, and multiple downstream ports, all without the need for external glue logic.
Let’s take a closer look at what makes this controller a reliable choice for next-generation USB system design.
