CAMBRIDGE, England and OSLO, Norway, April 14 /PRNewswire/ --

- Oslo-Based Start-Up Will Develop Very Low Energy Consumption Solution 
Using Industry-Leading ARM Technology

ARM (LSE:ARM); (Nasdaq: ARMH) and Energy Micro, an Oslo based
semiconductor start-up, today announced that they have signed a licensing
agreement for the ARM(R) Cortex(TM)-M3 processor. Following the general trend
in the market to move from 8- and 16-bit architectures to 32-bit, Energy
Micro will introduce its first ultra low-power 32-bit microcontroller family,
based on the ARM Cortex-M3 processor, in the second quarter of 2009.

Energy Micro's main objective is to produce the world's most
energy-friendly microcontrollers. The EnergetIC(TM) microcontroller family
from Energy Micro will have energy consumption at a level that is far below
today's solutions, thus enabling significant improvements in battery life,
longer lifetime of electronic products and reduced disposals. The combination
of an extremely efficient active processing mode, a wide range of power
saving modes and a flexible set of system peripherals will provide true value
to its users.

"With our focus on low energy consumption, integration, system
performance and low cost, the ARM Cortex-M3 processor is the right choice for
us," said Geir FÞrre, CEO of Energy Micro. "The strong ecosystem of available
tools, software and knowledge within the ARM Connected Community(R) is also
very important for us and our customers."

"Striving for low energy consumption has never been more important and
Energy Micro has chosen the ARM Cortex-M3 processor in its mission to make
the world's most energy-friendly microcontrollers," said Graham Budd,
executive vice president and general manager, Processor Division, ARM. "The
32-bit microcontroller marketplace is rapidly consolidating around the
Cortex-M3 processor to provide a fast and reliable path to market, which
Partners such as Energy Micro are aggressively leveraging to displace legacy
devices."

Energy Micro also licensed various physical IP from the ARM Artisan(R)
physical IP family, plus a number of ARM PrimeCell(R) peripheral IP blocks.
