EFM32 Leopard Gecko Family

EFM32LG Data Sheet

The EFM32 Leopard Gecko MCUs are the world’s most energy-

friendly 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 Cortex-

M3 processor, making it perfect for battery-powered systems and systems with high-per-

formance, low-energy requirements.

EFM32LG applications include the following:

• Energy, gas, water and smart metering

• Health and fitness applications

• Smart accessories
