The EFM32G is the world's most energy efficient microcontroller, which combines unmatched performance with ultra low power consumption in both active and sleep modes. EFM32G devices consume as little as 180 μA/MHz in run mode, and as little as 900 nA with a Real Time Counter running, Brown-out and full RAM and register retention. EFM32G's low energy consumption outperforms any other available 8-, 16-, and 32- bit solution. The EFM32G includes autonomous and energy efficient peripherals, high overall chip- and analog integration, and the performance of the industry standard 32-bit ARM Cortex-M3 processor.
