USB Type-C Opens Possibilities for DC Power Distribution into Buildings

The USB 3.0 Promoter Group today announced the completion of the USB Type-C specification that defines the next generation USB connector. The USB Type-C specification establishes a new cable and connector scheme tailored to fit mobile device product designs, yet robust enough for laptops and tablets. With this release, the specification has been transferred to the USB Implementers Forum (USB-IF) for ongoing management and the establishment of a compliance and certification program.

"The USB Type-C connector is a major breakthrough that combines 10 Gbps high-speed communication with charging capability scalable up to 100W, while consolidating numerous cables into one robust, unique cable with reversible plug orientation and cable direction that significantly improves the user experience," said Joel Huloux, director, Standardization and Industry Alliances, STMicroelectronics. "The USB Type-C cable addresses future needs and, on the road or in the office, opens the door to exciting new applications in the realm of dc power distribution into buildings, video transmission, accessory support and higher communication speed."

"Interest in the USB Type-C connector has not only been global, but cross-industry as well," said Brad Saunders, USB 3.0 Promoter Group Chairman. "Representatives from the PC, mobile, automotive and IoT industries have been knocking down our door anticipating this new standard. This specification is the culmination of an extensive, cooperative effort among industry leaders to standardize the next generation USB connector as a long-lasting, robust solution."

The USB Type-C specification defines the physical USB Type-C cable and connector form factor along with the functional requirements for detecting and managing USB connections over an extensible wiring architecture. This new cable and connector supports USB performance at SuperSpeed USB 10 Gbps (USB 3.1) and USB Power Delivery up to 100W.

The new USB Type-C plug and receptacle will not directly mate with existing USB plugs and receptacles (Type-A, Type-B, Micro-B, etc.); however, the USB Type-C specification defines passive new-to-existing cables and adapters to allow consumers to use the new connector with their existing products.

"USB has the luxury of consumer familiarity and trust, and as we adapt the technology for the future we are committed to ensuring the USB brand promise continues with this new USB Type-C connector and cable," said Jeff Ravencraft, USB-IF President and COO. "The USB-IF is working to establish certification and compliance testing so that consumers can have the same confidence in the next generation of certified USB technology."

"The release of the USB Type-C specification is the final piece in developing a single-cable solution. The combination of SuperSpeed USB 10 Gbps and USB Power Delivery up to 100W with the slim, user-friendly USB Type-C connector provides endless possibilities. An ideal example use case is a docking solution that features a single USB Type-C cable connection to dock and power your PC, and a hub within the dock that can connect multiple screens streaming video with additional bandwidth available for many other functions," Ravencraft continued. "USB is an adaptable solution that is flexible enough to fit the varied needs of consumers. Developers interested in implementing the new USB Type-C specification have the opportunity to learn technical details at upcoming developer conferences currently being planned," he concluded.
