Mar 21, 2006

March 21, 2006 – National Semiconductor Corporation (NYSE:NSM) today announced that Design News Magazine has honored National’s PowerWise™ technology and LP5550 energy management unit (EMU) with its prestigious Golden Mousetrap Award.  National was selected by the readers from among four finalists in the power management and control category.

“Design News Magazine is pleased to recognize National Semiconductor’s power management technology with a Golden Mousetrap Best Product Award this year," said Karen A. Field, editor-in-chief of Design News Magazine.  "Our readers named National Semiconductor's PowerWise technology and LP5550 EMU as the ‘Best of the Best’ power management and control technology for design engineers introduced in the past year.”

For more than 20 years, Design News Magazine has recognized the most significant individual and corporate technical achievements in the electronics community.  After Design News editors selected finalists from hundreds of entries, the magazine’s readers chose National’s PowerWise technology and LP5550 EMU from among four finalists. Design News, a Reed Business publication, is published monthly to 170,000 engineers who design products ranging from motion control to spacecraft.  Readers completed voting in February 2006. The March 20 edition of Design News will feature National’s PowerWise technology and LP5550 EMU.

"We are honored that Design News Magazine chose National’s PowerWise technology and LP5550 EMU for the illustrious Golden Mousetrap Award," said Ravindra Ambatipudi, director of Power Management Products, National Semiconductor.  "This award recognizes the dedication and diligence of National’s PowerWise engineering teams.”

About National’s PowerWise Technology and LP5550 EMU
The first of its kind, National Semiconductor’s PowerWise technology is an energy-saving technique for extending the battery life of feature-rich portable electronic devices, particularly mobile phones.  PowerWise technology reduces the power consumed by high data-rate processors up to 70 percent and substantially increases battery life.  Ultimately, consumers enjoy data-intensive features without additional charging periods.

PowerWise technology is a comprehensive, system-level solution for reducing processor power consumption in both data-intensive and stand-by modes of operation.  During operation, the PowerWise technology ensures that the processor operates at power supply voltages best suited for the environmental conditions, semiconductor process variations or applications software workload.  The LP5550 EMU manages specific voltages on the smaller silicon geometry processors so that stand-by power consumption is also reduced.  For more information, visit powerwise.national.com.
