New Micro-USB Specification Targets Mobile Devices

The USB Implementers Forum completed work on a new Micro-USB specification designed to replace many of the Mini-series plugs and receptacles currently used in portable products.



The new 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 USB Implementers Forum said the Micro-series' stainless steel shell should yield more than 10,000 insertion cycles for longer life and higher durability. A passive latching mechanism provides for higher extraction forces.
