Energy Micro AS


Energy Micro develops, markets and sells the world's most energy friendly microcontrollers, based on the industry leading ARM® Cortex™-M3 32-bit architecture. The company was founded in 2007 by experienced semiconductor professionals with previous expertise from Chipcon, Texas Instruments, Atmel and Nordic Semiconductor.

Energy Micro is the specialist in low energy microcontroller design. The energy friendly EFM®32 Gecko microcontroller family integrates features and techniques that contribute to the ultra-low-power consumption. EFM32 development kits and energyAware™ software helps designers find, remove, and improve energy bugs in real-time.

The 32-bit EFM32 Gecko from Energy Micro is perfect in energy sensitive applications, including energy metering, building automation, security and medical equipment, and the EFM32 Gecko Microcontroller has been proven capable of consuming a quarter of the energy required by 8-bit, 16-bit or 32-bit alternatives.


29 June 2013   -   Energy Micro "Wonder Gecko" Cortex-M4 Microcontrol

The EFM32 Wonder Gecko family consists of 60 scalable memory and package configurations with up to 256 KB Flash and 32 KB RAM. Available in QFN64 to BGA120 options.

12 December 2012   -   Energy-Efficient MCUs for Remote Medical Systems

Energy Micro announces a partnership with Lamprey Networks Inc. (LNI) to provide energy friendly, secure and certified remote monitoring medical electronic systems.

Using a standard EFM32 starter-kit and HealthLink PC tools, the design includes a USB driver and communications protocol stack.

The demo platform is based on the USB versions of Energy Micro's EFM32 Leopard and Giant Gecko ranges of Cortex-M3 based. It will also be applicable to the forthcoming Cortex-M4 floating-point Wonder Gecko.

The energy efficient 32-bit design facilitates fast, reliable development of patient monitoring systems, many of which require high performance processing matched to the lowest possible energy consumption in order to maximize battery life.

In addition to USB stacks, LNI provides implementations of their HealthLink interface and protocols that operate on common platforms such as Android, Windows, Linux and iOS.

30 November 2012   -   Embedded MCUs Get Smarter

Energy efficiency is increasingly being recognized as a key performance attribute of many electronic systems - and of embedded designs in particular.

16 November 2012   -   Heads-Up for New Product Releases in 2013

Energy Micro will launch three new energy-efficient product series in 2013, expanding the existing EFM32 Gecko ARM Cortex-M series of ultra low power microcontrollers by 50%.

New products will include Cortex-M0+ and Cortex-M4F microcontroller series and ultra low power, multi-standard radio transceivers with integrated Cortex-M3 cores.

In October 2012, the company secured an additional $12 million funding from a combination of new and existing investors to accelerate development of energy friendly MCUs and RF technology.

3 October 2012   -   The Lizard Lounge is Now Open!

This is an EFM32 forum and knowledge base hosted by Energy Micro support team to give first class EFM32 technical answers that all users can benefit from in the years to come.

Lizard of the year award
The Lizard Lounge includes a reputation system where users can push a "like" button on each other's posts. The accumulated amount will add up to your reputation score. At next year's Annual Distribution Meeting we will have an award for the Disti/Rep member with the highest reputation score in the Lizard Lounge.

The forum is a great way to find help on issues quickly and can greatly help reduce time-to-market for a developer.

11 September 2012   -   EFM32 Gecko - Lowest Energy Microcontroller

Benchmark tests using IAR Embedded Workbench® for ARM version 6.40 confirms EFM32 Gecko as lowest energy microcontroller - even beating rivals with Cortex-M0+ Core.

8 February 2012   -   World's most energy friendly Linux for Cortex-M3

This new port of µClinux features the latest version 3.2 Linux kernel, and gives embedded designers all of the cost and time-to-market benefits of using an open source embedded operating system, while maintaining low current consumption of just 1.6mA when in idle mode. Energy Micro, the energy friendly microcontroller and Radio Company assisted and supported Pengutronix to complete the port to the Giant Gecko MCU range, the industry's leading family of low-energy microcontrollers.

Using µClinux reduces design cycles and accelerates time-to-market by giving the designer access to ready-made system functions such as IP connectivity, file systems, and multi-tasking. Users can also employ the broad range of free software and drivers available as open source, within a robust, portable open source framework.

The Embedded Linux/Microcontroller project is a port of Linux designed for systems without a memory management unit (MMU). The OS is an excellent performer for embedded use giving applications access to a rich set of free libraries and core OS services. Designers can choose which functionality to include in their systems, allowing them to trade sophistication with code footprint - often a critical factor in embedded designs.
