EFM32 Leopard Gecko Family EFM32LG Data Sheet
The EFM32 Leopard Gecko MCUs are the world’s most energyfriendly microcontrollers.
The EFM32LG offers unmatched performance and ultra-low power consumption in both active and sleep modes. EFM32LG devices consume as little as 0.65 μA in Stop mode and 211 μA/MHz in Run mode. It also features autonomous peripherals, high overall chip and analog integration, and the performance of the industry standard 32-bit ARM CortexM3 processor, making it perfect for battery-powered systems and systems with high-performance, low-energy requirements.
EFM32LG applications include the following:
Energy, gas, water and smart metering Health and fitness applications Smart accessories
Alarm and security systems Industrial and home automation
