USB Type-C® Basics

For a detailed description of the Type-C specifications refer to the USB-IF website to download the latest information. Understanding the basic concepts of the USB Type-C specification will aid in understanding the operation of the TPS2583xA-Q1 (a DFP device).

USB Type-C removes the need for different plug and receptacle types for host and device functionality. The Type-C receptacle replaces both Type-A and Type-B receptacle since the Type-C cable is plug-able in either direction between host and device. A host-to-device logical relationship is maintained via the configuration channel (CC). Optionally hosts and devices can be either providers or consumers of power when USB Power Delivery (PD) communication is used to swap roles.

All USB Type-C ports operate in one of below three data modes:

  • Host mode: the port can only be host (provider of power)
  • Device mode: the port can only be device (consumer of power)
  • Dual-Role mode: the port can be either host or device

Port types:

  • DFP (Downstream Facing Port): Host
  • UFP (Upstream Facing Port): Device
  • DRP (Dual-Role Port): Host or Device

Valid DFP-to-UFP connections:
