The USB 3.0 Promoter Group has 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. The specification has now been transferred to the USB Implementers Forum (USB-IF) for ongoing management and the establishment of a compliance and certification program.
USB 3.0 Promoter Group Chairman Brad Saunders explains that interest in the USB Type-C connector has not only been global, but cross-industry as well, especially from the PC, mobile, automotive and IoT segments. The USB Type-C specification is the culmination of an extensive, cooperative effort among industry leaders to standardise 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.
Key features of the USB Type-C connector include a completely new design tailored for emerging product designs, robust enough for laptops and tablets, slim enough for mobile phones, and similar in size to USB 2.0 Micro-B; usability enhancements including reversible plug orientation and cable direction; support for scalable power charging; and future scalability to support future USB performance needs.
Mechanical specifications of the USB Type-C connector: Receptacle opening ~8.4mm x ~2.6mm; durability 10,000 cycles; improved EMI- and RFI-mitigation features; and power delivery capacity of 3A for standard cables and 5A for connectors.
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.
Observing how USB has the advantage of consumer familiarity and trust, USB-IF President and COO Jeff Ravencraft reiterates their commitment to ensuring the USB brand promise continues with the new USB Type-C connector and cable as they adapt the technology for the future. He added that the USB-IF was working to establish certification and compliance testing so that consumers can have the same confidence in the next generation of certified USB technology.
The USB 3.0 Promoter Group, comprising of Hewlett-Packard Company, Intel Corporation, Microsoft Corporation, Renesas Electronics, STMicroelectronics and Texas Instruments, developed the USB 3.1 specification released in July 2013.
