Take a more detailed look at the recently announced Energy Micro MCUs, the EFM32G family. The company claims the ARM Cortex M3-based EFM32G range are the most energy efficient MPUs available.
In 'run mode', current consumption is under 180µA/MHz while executing real code from flash; stand-by consumption is typically 900nA with real-time clock, power-on reset, and brown-out detector running, and RAM data and CPU state retained; and in deepest sleep, quiescent is less than 20nA, states CEO Geir Forre.
As well as detailed look at the chips, associated dev kit and the MCU architecture, there is a look at the overall product family and possible applications.
