EFM32 Gecko Family
EFM32TG Data Sheet
The EFM32 Gecko MCUs are the world’s most energy-friendly mi-
crocontrollers.
The EFM32TG offers unmatched performance and ultra low power consumption in both
active and sleep modes. EFM32TG devices consume as little as 0.6 μA in Stop mode
and 150 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.
EFM32TG 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 32 MHz
• Ultra low power operation
• 0.6 μA current in Stop (EM3), with
brown-out detection and RAM retention
• 51 μA/MHz in EM1
• 150 μA/MHz in Run mode (EM0)
• Fast wake-up time of 2 µs
• Hardware cryptography (AES)
• Up to 32 kB of Flash and 4 kB of RAM
