General Capabilities

  • xHCI (USB 3 host controller) and xDCI (USB 3 device controller) implemented in the processor in addition to the controllers in the PCH.
  • No support for USB Type-A on the processor side, For USB Type-A implementation and capabilities refer to Intel® 600 Series Chipset Family On-Package Platform Controller Hub (PCH) Datasheet, Volume 1 of 2 (691222).
  • Intel AMT/vPro over Thunderbolt docking.
  • Support power saving when USB-C* disconnected.
  • Support up to four simultaneous ports.
  • DbC Enhancement for Low Power Debug until Pkg C6
  • Host
    • Aggregate BW through the controller at least 3 GB/s, direct connection or over USB 4.
    • Wake capable on each host port from S0i3, Sx: Wake on Connects, Disconnects, Device Wake.
  • Device
    • Aggregate BW through xHCI controller of at least 3 GB/s
    • D0i2 and D0i3 power gating
    • Wake capable on host initiated wakes when the system is in S0i3, Sx Available on all ports
  • Port Routing Control for Dual Role Capability
    • Needs to support SW/FW and ID pin based control to detect host versus device attach
    • SW mode requires PD controller or other FW to control
  • USB-R device to host controller connection is over UTMI+ links.

  2. Supported only on Native connector.
  3. USB 3 supported link rates:
    1. USB 3 Gen 1x1 (5 Gbps)
    2. USB 3 Gen 2x1 (10 Gbps)
  4. USB4 operating link rates (including both rounded and non-rounded modes for Thunderbolt 3 compatibility):
    1. USB 4 Gen 2x2 (20 Gbps)
    2. USB 4 Gen 3x2 (40 Gbps)
    3. 10.3125 Gbps, 20.625 Gbps - Compatible to Thunderbolt 3 non-rounded modes.
  5. USB 2 interface supported over Type-C connector, sourced from PCH.
  6. USB Type-A connector is not supported.
  7. Port group is defined as two ports sharing the same USB4 router, each router supports up to two display interfaces.
  8. display interface can be connected directly to a DP/HDMI/Type-C port or thru USB 4 router on a Type-C connector.
  9. If two ports in the same group are configured to one as USB4 and the other as DP/HDMI fixed connection each port will support single display interface.
