EFM32 Tiny Gecko Series 1 Family
EFM32TG11 Family Data Sheet
The EFM32 Tiny Gecko Series 1 MCUs are the world’s most ener-
gy-friendly microcontrollers, featuring new connectivity interfaces
and rich analog features.
EFM32TG11 includes a powerful and efficient 32-bit ARM® Cortex®-M0+ and provides
robust security via a unique cryptographic hardware engine supporting AES, ECC, SHA,
and True Random Number Generator (TRNG). New features include a CAN bus control-
ler, highly robust capacitive sensing, and LESENSE/PCNT enhancements for smart en-
ergy meters. These features, combined with ultra-low current active mode and short
wake-up time from energy-saving modes, make EFM32TG11 microcontrollers well suited
for any battery-powered application, as well as other systems requiring high performance
and low-energy consumption.
Example applications:
• Smart energy meters
• Industrial and factory automation
• Home automation and security
• Entry-level wearables
• Personal medical devices
• IoT devices
