EFM32WG Datasheet Text
EFM32 Gecko Family EFM32WG Data Sheet
The EFM32 Gecko MCUs are the world’s most energy-friendly microcontrollers.
The EFM32WG offers unmatched performance and ultra-low power consumption in both active and sleep modes. EFM32WG 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 CortexM4 with Floating-Point Unit (FPU) processor, making it perfect for battery-powered systems and systems with high-performance, low-energy requirements.
EFM32WG applications include the following:
- Energy, gas, water, and smart metering
- Health and fitness applications
- Smart accessories
- Alarm and security systems
- Industrial and home automation
