Silicon Labs EFM32GG11™ Giant Gecko Series 1 32-bit MCUs

Silicon Labs EFM32GG11™ Giant Gecko Series 1 32-bit MCUs are Arm® Cortex®-M4 based 32-bit microcontrollers (MCUs). The EFM32GG11 provides robust security via a unique cryptographic hardware engine. The engine supports AES, ECC, SHA, and True Random Number Generator (TRNG). Features include an SD/MMC/SDIO controller, Octal/ Quad-SPI memory controller, 10/100 Ethernet MAC, and dual CAN bus controller.

These MCUs offer highly robust capacitive sensing, an enhanced alpha blending graphics engine, and LESENSE/PCNT enhancements for smart energy meters. The EFM32GG11 features an ultra-low current active mode and short wake-up time from energy-saving modes. This makes the EFM32GG11 ideal for any battery-powered application and other systems requiring high performance and low energy consumption.
