Ember and ARM Target High Performance ZigBee Networks

BOSTON, MA and CAMBRIDGE, UK -- April 28, 2009 – ARM [(LSE: ARM); (Nasdaq: ARMH)] and Ember announced that Ember’s soon to be introduced, next-generation ZigBee semiconductors will utilize the ARM® Cortex™-M3 processor setting a new bar for high performance and low power consumption in the fast growing ZigBee market.

Ember is the leader in the ZigBee industry with a market share of more than 65 percent and an array of customers that are global leaders in smart metering, home automation and commercial building automation. Ember licensed the Cortex-M3 processor to deliver increasingly sophisticated solutions for applications such as Smart Energy, home area networks, home health care and security systems.

The 32-bit ARM Cortex-M3 processor brings together multiple technologies to reduce memory and processor size while delivering industry-leading performance and power efficiency and providing an ideal platform to accelerate the migration of thousands of applications to 32-bit microcontrollers. The Cortex-M3 processor will significantly enhance performance, sophistication and security, and enable Ember to continue providing the ZigBee industry with powerful and power efficient system-on-chips (SoCs).

The ARM Cortex-M3 processor delivers outstanding computational performance and exceptional system response to interrupts while meeting low cost requirements through a small core footprint, reduced pin count, low power consumption and industry-leading code density thereby enabling the use of smaller memories.

“Our partnership with industry leader Ember demonstrates the exceptional momentum the ARM Cortex-M3 processor is having in low power markets,” said Eric Schorn, vice president marketing, processor division, ARM. “The Cortex-M3 processor, along with the industry’s leading tools ecosystem, delivers the higher performance required for more sophisticated applications while retaining low-power leadership.”

Ember’s low-power, wireless ZigBee systems include tightly integrated chips, mesh networking software supporting the ZigBee PRO Feature Set, and development and debugging tools that enable OEMs to quickly bring ZigBee products to market. Ember delivered both the industry’s first ZigBee SoC and ZigBee network co-processor

“ZigBee applications are becoming increasingly demanding and a critical component in solving some of the most vexing problems of our time, such as managing energy more effectively, and we intend to be at the forefront of that revolution,” said Ember CEO, Bob LeFort. “ARM is the acknowledged leader in processor technology, as Ember is in wireless mesh networking technology, so ours is a natural alliance to lead the blossoming ZigBee market into the future.”
