O2Micro Receives Key CardBus Controller Patent

Tuesday October 8, 8:31 am ET


SANTA CLARA, Calif. & GEORGE TOWN, Grand Cayman--(BUSINESS WIRE)--Oct. 8, 2002--O2Micro® International Limited (Nasdaq:OIIM - News), a leading supplier of innovative power management and security ICs to mobile computer and communications manufacturers, was granted 10 claims under Taiwan patent number 155,891 for its SmartCardSensing® Card Detection Circuit.

This patented technology is implemented in the SmartCardBus® (OZ711E series) and 4-in-1 MemoryCardBus(TM) (OZ711M series) family of CardBus Controllers. It enables O2Micro's advanced CardBus controllers to automatically detect and communicate with ISO 7816 Smart Cards and popular flash media cards (SD Memory Card, Memory Stick(TM), MultiMediaCard (MMC) and SmartMedia(TM)), in addition to 16- and 32-bit PC Cards.


Various card types can be inserted into the PCMCIA slot containing O2Micro's SmartCardBus® and 4-in-1 MemoryCardBus(TM) products using either a dedicated slot or a low cost passive PCMCIA standard 68-pin adapter, which requires no additional pins. Low cost Smart Card and 4-in-1 flash media passive adapters are already available in the market from multiple sources. Using the existing PCMCIA slot to support these additional functions eliminates the need to add dedicated slots to crowded side panels of a notebook computer.


"This patent continues O2Micro's leadership in the advancement of CardBus controller technology," stated Max Huang, vice president of O2Micro's Intelligent E-Commerce Business Unit. "The addition of broadly based foreign patents significantly strengthens our intellectual property and market position worldwide. This Taiwan patent is pivotal as Taiwan is the largest market for the manufacture of notebook computers."


O2Micro's SmartCardSensing technology allows a user-friendly, real plug-n-play environment. Plus, it gives PC OEM's the option to use low cost, passive adapters to extend the value of the existing PCMCIA card slot, and utilize a regular notebook computer as a digital hub.
