This supplement to the USB 3.1 specification is anticipated to be completed by the middle of next year. It will be similar to Apple's Lightning connector, sporting a smaller size and reversible design.
Key characteristics of the USB Type-C connector and cable solution include:
● An entirely new design tailored to work well with emerging product designs
● New smaller size – similar in size to the existing USB 2.0 Micro-B
● Usability enhancements – users will no longer need to be concerned with plug orientation/cable direction, making it easier to plug in
● The Type-C connector and cable will support scalable power charging
● Scalability – the connector design will scale for future USB bus performance
As 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.), the Type-C specification will define passive new-to-existing cables and adapters to allow users to use their existing products.
"While USB technology is well established as the favored choice for connecting and powering devices, we recognize the need to develop a new connector to meet evolving design trends in terms of size and usability," said Brad Saunders, USB 3.0 Promoter Group Chairman. "The new Type-C connector will fit well with the market’s direction and affords an opportunity to lay a foundation for future versions of USB."
“Intel is excited to see the development of the new thin Type-C connector as it will enable an entirely new super thin class of devices from phones to tablets, to 2-in-1s, to laptops to desktops and a multitude of other more specific usage devices,” said Alex Peleg, Vice President, Platform Engineering Group. “This new industry standards-based thin connector delivering data, power and video is the only connector one will need across all devices.”
The USB Type-C specification is targeted for industry review during the first quarter of 2014 and a final specification is expected to be published by the middle of 2014.
