Energy Micro

Geir Førre, President and CEO at Energy Micro on their adoption of ARM’s Cortex-M3 processor technology

Founded in 2007, Energy Micro is the creator of the world’s most energy friendly microcontroller. Our EFM32 Gecko microcontroller product family is based on the industry- leading ARM Cortex-M3 processor. As a true innovator, our bold mission was to produce a 32-bit microcontroller capable of achieving a 4x increase in battery life and an easy-to-use development environment enabling designers to cut system development times by a half.

There are an ever-growing number of embedded applications where energy saving and efficiency are at the very top of developers’ priorities. Such design criteria can be due to government regulations (e.g. metering applications), a requirement to increase battery life, or simply a need to reduce power consumption. Our EFM32 Gecko family of energy friendly microcontrollers therefore combines a smart ARM Cortex-M3 with a range of energy saving features, including advanced low power peripherals, a peripheral reflex system, well-architected energy modes and an advanced energy monitoring utility. The resulting low energy operation can help extend typical battery lifetime to more than 20 years.

We chose to build our Gecko microcontrollers around the ARM Cortex-M3 processor because it offers superior energy efficiency. The Cortex-M3 is also a smart, high-performance and low-power processor with a strong ecosystem of tools and software, that many of our customers already know how to use. For battery powered applications, our target is to make the battery last as long as possible and so we need to reduce power consumption as much as possible. As a high- performance processor, the ARM Cortex-M3 can finish tasks faster, enabling the microcontroller to spend most of its time in stand-by mode.

Our EFM32 Gecko microcontrollers are being designed into a broad range of energy sensitive applications including energy metering, home and building automation, alarm and security systems and medical and lifestyle equipment and our goal is to sell 100 million by 2013.
