EFM32 Giant Gecko Family
EFM32GG Data Sheet
The EFM32 Giant Gecko MCUs are the world’s most energy-
friendly microcontrollers.
The EFM32GG offers unmatched performance and ultra low power consumption in both
active and sleep modes. EFM32GG devices consume as little as 0.6 μA in Stop mode
and 180 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.
EFM32GG applications include the following:
• Smart metering
• Water metering
• Gas metering
• Industrial and home automation
• Alarm and security systems
• Health and fitness applications
KEY FEATURES
• ARM Cortex-M3 at 48 MHz
• Ultra low power operation
• 0.6 μA current in Stop (EM3), with
brown-out detection and RAM retention
• 45 μA/MHz in EM1
• 180 μA/MHz in Run mode (EM0)
• Fast wake-up time of 2 µs
• Hardware cryptography (AES)
• Up to 1024 kB of Flash and 128 kB of
