7. USB Type-C™ Overview 8
Enable new and exciting host and device form-factors where size, industrial design and style are important parameters
Work seamlessly with existing USB host and device silicon solutions
Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation

Configuration
Channel
Receptacle
Two pins on the USB Type-C receptacle, CC1 and CC2, are used in the discovery, configuration and management of
connections across the USB Type-C cable
Plug
On a standard USB Type-C cable, only a single CC wire within each plug is connected through the cable to establish signal
orientation. The other CC pin is repurposed as VCONN for powering electronics
Also, only one set of USB 2.0 D+/D- wires are implemented
Enhanced ease of use

9. USB Type-C™ and USB Power Delivery 10
Communication across the channel uses Biphase Mark Coding (BMC) over CC in
