TomTom Selects MEMSIC's Thermal Accelerometer for Its New Car Navigation System; TomTom Uses MEMSIC's Thermal Accelerometer in the TomTom GO

N. ANDOVER, Mass.--Sept. 14, 2004--MEMSIC, the leading provider of CMOS-based MEMS accelerometers/sensors, announced that it has been selected to supply its thermal accelerometers product to TomTom for use in their all in one car navigation device, the TomTom GO. The accelerometer will be used for determining travel distance using "dead reckoning" navigation and is activated when the GPS signal is lost. GPS signal loss can occur for example, when traveling through a tunnel or in underground parking structures.

"Our highly reliable thermal accelerometer product does not require special manufacturing systems, and currently has a failure rate of 1.75ppm," said MEMSIC CEO, Dr. Yang Zhao. "Once again MEMSIC has demonstrated through higher reliability, that our accelerometers provide the lowest total cost of ownership in the industry."

Through established manufacturing partnerships in Asia with TSMC and Fujitsu, MEMSIC has reduced operational costs by outsourcing nearly 90% of its manufacturing, resulting in products that offer the highest reliability, meet the most stringent quality standards, and offer customers a significantly lower cost of ownership vs. competing technologies. MEMSIC also recently opened its new 45,000 square foot facility in Wuxi, Jiangsu Province, China. About a two-hour drive from Shanghai, this new facility has a manufacturing capacity of 3M units per month.

As the only dual axis accelerometer fabricated on a monolithic CMOS process, MEMSIC's cost effective products are advancing into many new consumer applications and are being used for virtually any application that requires the sensing of motion, acceleration, vibration or tilt.

About MEMSIC, Inc.

MEMSIC, Inc. is a semi fabless IC company that specializes in MEMS (Micro Electric Mechanical Systems) ICs (Integrated Circuits). MEMSIC has developed and brought to market a unique CMOS-based accelerometer that contains no moving parts. MEMSIC's product combines the sensor and associated electronics onto a single chip that is manufactured on a standard, sub-micron CMOS process. By breaking the traditional technology barriers in cost and reliability, MEMSIC technology turns traditionally expensive and not-so-reliable MEMS accelerometers into highly affordable standard IC products with the highest long-term reliability and performance available today in the IC industry.
