Let MindShare Bring "USB Type-C Interconnect and Power Delivery" to Life for You
This introductory course is primarily concerned with topics described in two documents: USB Type-C Cable and Connector Specification and the USB Power Delivery Specification. The USB Type-C connectors address several limitations of traditional USB Type A and Type B connectors related to size, mechanical reliability, and the need to maintain proper cable and plug orientation. Type-C connector and cables have no required orientation and support USB 2.0, USB 3.1, as well as sideband signals for communications, audio, HDMI, or other purposes. In addition, Type-C brings a new set of power delivery capabilities as defined in USB Power Delivery Specification, including negotiated switching of upstream/downstream port roles and the device responsible for sourcing VBUS power.
