Micro-series USB technology will replace Mini-series USB in OTG products

BEAVERTON, Ore.-- The USB Implementers Forum, Inc. (USB-IF) today announced the completion of the Micro-USB specification, a new connector technology that will replace many of the Mini-series plugs and receptacles currently used in portable products. This USB-IF connector specification was developed to support the growing miniaturization trend for portable devices, as well as the continued adoption of USB in mobile phones.

“As portable devices such as mobile phones, PDAs and digital cameras get smaller and more compact, manufacturers recognized the need for a new USB connector specification to suit the design of these new products,” said Jeff Ravencraft, chairman and president of the USB-IF. “USB-IF developed the Micro-USB specification to adapt to sleek new design needs.”

The Micro-USB specification supports the USB On-The-Go (OTG) supplement, which was created in response to the growing need for portable devices to communicate directly with each other when a PC is not available. Micro-series definitions include: Micro-B receptacles for standard devices, Micro-AB receptacles for OTG devices, Micro-A and Micro-B plugs, and standard cables. The Micro-series are unique in that they feature a stainless steel shell, which yields more than 10,000 insertion cycles for longer life and higher durability, and passive latching mechanism for higher extraction forces. The Micro-series connectors will continue to maintain the ease-of-use and speed of the USB technology.

"Nokia always strives for great user experience. The new micro-USB that is standardized, miniaturized, and optimized for mobile use helps us in that important task. The micro-USB offers innovative design and a flexible platform that our technical teams can easily take on board while working with new product designs," said Jouko Junkkari, Director within Nokia Technology Platforms.
