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

use

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

USB Type-C™ and USB Power Delivery 10

Communication across the channel uses Biphase Mark Coding (BMC) over CC in
