The latest generation of USB technology was unveiled back in April at the Intel Developer Forum conference in China. Known as USB Type-C, it promised to improve on current USB technology by offering a symetrical design (no more trying to figure out which side is up), reversible ends (the same connector at both ends), better transfer speeds and more. The specification was not complete at the time but the USB 3.0 Promoter Group today announced that they have now reached this milestone.
“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.”
Along with being symmetrical and reversible, USB Type-C cables will also be able to charge devices with support for delivery capacities of 3A for standard cables and 5A for connectors. While not compatible with current USB plugs, the specification does support the use of passive new-to-existing cables and adapters to allow consumers to use the new connector with their existing products. The smaller prong size will also mean that it will be useable in a wide range of devices.

The USB Type-C specification has been transferred to the USB Implementers Forum (USB-IF) which will establish and manage a compliance and certification program to go with it.
With the specification finalized, it may not be much longer before we start seeing USB Type-C making its way onto our mobile devices.
