EFM32GG11 Family Data Sheet
The EFM32 Giant Gecko Series 1 MCUs are the world’s most
energy-friendly microcontrollers, featuring new connectivity interfa-
ces and user interface features.
EFM32GG11 includes a powerful 32-bit ARM
®
Cortex
®
-M4 and provides robust security
via a unique cryptographic hardware engine supporting AES, ECC, SHA, and True Ran-
dom Number Generator (TRNG). New features include an SD/MMC/SDIO controller, Oc-
tal/Quad-SPI memory controller, 10/100 Ethernet MAC, CAN bus controller, highly robust
capacitive sensing, enhanced alpha blending graphics engine, and LESENSE/PCNT en-
hancements for smart energy meters. These features, combined with ultra-low current
active mode and short wake-up time from energy-saving modes, make EFM32GG11 mi-
crocontrollers well suited for any battery-powered application, as well as other systems
requiring high performance and low-energy consumption.
