The Renesas μPD720201 is a USB 3.0 host controller designed to add high-speed USB connectivity to desktop computers and other systems. It supports up to four USB 3.0 SuperSpeed ports and connects to the host system through a PCI Express Gen 2 interface.
The controller supports theoretical USB 3.0 transfer speeds of up to 5 Gbps when used with compatible SuperSpeed devices and cables. It is fully compliant with the USB 3.0 specification and maintains backward compatibility with USB 2.0 devices, allowing older peripherals to continue working.
The μPD720201 was commonly used on PCI Express USB expansion cards and built-in motherboard USB controllers. Depending on the operating system and hardware configuration, a dedicated Renesas USB 3.0 driver may be required for the controller to function correctly and provide full SuperSpeed support.
