ARM Announces Extension of Commitment To The ARM Roadmap by STMicroelectronics And Licensing Of Two Advanced Microprocessor Cores

CAMBRIDGE, UK – Sept. 15, 2003 –ARM, [(LSE:ARM);(Nasdaq:ARMHY)], the industry's leading provider of 16/32-bit embedded RISC microprocessor solutions, today announced that STMicroelectronics (NYSE:STM) has extended its ARM® technology license. This extension will enable STMicroelectronics to continue to design and manufacture products based on a broad range of ARM microprocessor cores.

In addition, STMicroelectronics has licensed two of the most advanced ARM microprocessor cores, the ARM1026EJ-S™ core and the award-winning ARM1136JF-S™ core, as part of its ongoing commitment to the ARM architecture.

STMicroelectronics has been a prominent ARM Partner since its first license in 1998 for the industry-leading ARM7TDMI® core. Since then, STMicroelectronics has used ARM technology in a broad range of wireless and networking applications, and has also used ARM microprocessor cores to provide its customers with complex SoC solutions in the automotive and printer markets.

"ARM works closely with its Partners to ensure they are able to deliver innovative ARM Powered® products, and this latest agreement with STMicroelectronics enables the continued use of ARM technology in a wide range of applications," said Mike Inglis, EVP, Marketing, ARM. "STMicroelectronics' extension of their existing license is a major endorsement of ARM microprocessor technology by one of the world's leading semiconductor companies."

"STMicroelectronics technology based on the ARM architecture continues to deliver real value to our customers, and our partnership with ARM not only gives existing customers stability, but also shows where STMicroelectronics is headed in the future," said Bernard Fontan, director of Strategic Planning in ST's Telecom, Peripherals & Automotive Groups. "This new agreement provides a very good opportunity to create innovative new products that combine the latest ARM technology with our expertise in mobile communications, convergence and multimedia applications."
