On 3rd December, 2013 USB 3.0 Promoter Group announced the development of the next generation of USB connector has begun. The new USB Type-C connector, built initially on existing USB 3.1 and USB 2.0 technologies, is being developed to help enable thinner and sleeker product designs, enhance usability and provide a growth path for performance enhancements for future versions of USB. They also stated in press release that, this supplement to the USB 3.1 specification is anticipated to be completed by the middle of next year.
Every body knows the evolution of USB from its initial release. USB 2.0 got stable place because of its easy plug and play type. Interfacing of peripheral devices (I/0 and memory devices) to computer is easier due to USB and leads to the development of many portable devices. USB 2.0 has the drawback of low data transfer rates this was overcomed by future versions USB 3.0 & USB 3.1. Transfer rates steps up from Mbps to few Gbps (5 Gbps in USB 3.0 & 10 Gbps in USB 3.1). Now USB-IF entered into the development of next generation USB.
Some key characteristics of the USB Type-C connector and cable are
>>An entirely new design tailored to work well with emerging product designs.
>>New smaller/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.
Along with its features, one thing we should take in mind is that backtraps is not supported (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).
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. Further information regarding the specification and plans for pre-release industry reviews will be provided via the USB Implementers Forum (USB-IF) website.
I am also eagerly waiting for its official release so, let's waits for release of full specifications.
