BOSTON and CAMBRIDGE, England, April 28 /PRNewswire/ --

ARM [(LSE: ARM); (Nasdaq: ARMH)] and Ember announced that Ember's soon to
be introduced, next-generation ZigBee semiconductors will utilize the ARM(R)
Cortex(TM)-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 provides 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."
