USB 3 Controllers

Extensible Host Controller Interface (xHCI)

Extensible Host Controller Interface (xHCI) is an interface specification that defines Host Controller for a universal Serial Bus (USB 3), which is capable of interfacing with USB 1.x, 2.0, and 3.x compatible devices.

In case that a device (example, USB3 mouse) was connected to the computer, the computer will work as Host and the xHCI will be activated inside the CPU.

The xHCI controller support link rate of up to USB 3.2 Gen 2x2 (2x10G).

Extensible Device Controller Interface (xDCI)

Extensible Device Controller Interface (xDCI) is an interface specification that defines Device Controller for a universal Serial Bus (USB 3), which is capable of interfacing with USB 1.x, 2.0, and 3.x compatible devices.

In case that the computer is connected as a device (example, tablet connected to desktop) to another computer then the xDCI controller will be activated inside the device and will talk to the Host at the other computer.

The xDCI controller support link rate of up to USB 3.2 Gen 1x1 (5G).

Note:These controllers are instantiated in the processor die as a separate PCI function functionality for the USB-C* capable ports.
