when you thought a standard is a standard and established, the industry comes
around the corner with a new one/update. So happened yesterday, when the USB
Implementers Forum, Inc. (USB-IF) 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.
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.
According to the USB-IF, the Micro-series connectors will continue to
maintain the ease-of-use and speed of the USB technology.
