Trimble and Infineon Introduce Low-Power GPS Chipset in Smaller Package

New VQFN Chip Ideal for Handheld, Battery Operated Devices

NEW ORLEANS, March 17, 2003 -- Trimble (NASDAQ:TRMB) and Infineon Technologies (FSE/NYSE:IFX) today announced that their integrated Global Positioning System (GPS) chipset and software solution will be available in an even smaller package—a two-chip VQFN form factor less than a square centimeter. Based on Trimble's exclusive FirstGPS® technology, the VQFN chipset solution allows high-volume manufacturers of consumer products to easily and cost-effectively add GPS location capabilities with minimal impact on device size or battery life.
The announcement was made at CTIA Wireless 2003.
"As GPS is added to an increasing number of platforms, products and systems, Trimble and Infineon continue to drive the technology development curve by reducing the power and size of GPS chipsets," said Dennis Workman, vice president and general manager of Trimble's Component Technologies Division. "Our smallest, lowest power GPS chipset available, the VQFN chipset is ideal for the new small, highly integrated, battery powered mobile devices being developed today."
"The success of our initial chipset in automotive applications sets the stage for handheld applications which require much smaller packages," said Hubert Christl, general manager and vice president of the Local Area Wireless business unit at Infineon. "As space requirements for advanced battery powered devices decrease, the tiny VQFN chipset makes it easier for developers to integrate GPS functionality into a wide range of mobile devices."
About the Product
Almost half the size of the initial TSSOP chipset offering from Trimble and Infineon, the new 12-channel VQFN chipset and software solution is specifically designed for even smaller, power-sensitive, mobile information devices such as PDAs, laptops, digital cameras as well as automobile navigation systems.
The technology offers the lowest power consumption and smallest size of any GPS receiver on the market today. The chipset is comprised of one baseband ASIC and one RF ASIC. The baseband ASIC consumes less than 8 milliwatts and the RF ASIC less than 20 milliwatts. It is ideal for power-sensitive applications. FirstGPS technology is also communication independent and capable of interfacing with a wide range of mobile devices.
Infineon's implementation of the GPS baseband and RF ASICs is extremely compact. The baseband chip is packed in a 28-pin VQFN (6.5mm x 5.5mm - 35.75 sq mm) and the RF chip in a 24-pin VQFN (4.5mm x 3.5mm - 15.75 sq mm), both with a tiny 0.9 mm profile. The high level of integration enables a tiny footprint that is less than a centimeter square for the entire chipset solution. This tiny footprint facilitates the integration of GPS functionality into a variety of mobile devices without adversely affecting product form factor and size.
