EFM32™ Giant Gecko Series 1 32-bit Microcontrollers (MCUs)

The most integrated and high performance low power MCU available.

Our EFM32™ Giant Gecko Series 1 ARM® Cortex®-M4-based 32-bit microcontrollers (MCUs) are the most integrated and high performance low power MCUs available and include robust security via a unique cryptographic hardware engine supporting AES, ECC, SHA, and True Random Number Generator (TRNG). New features include a PDM sensor interface, an SD/MMC/SDIO controller, Octal/ Quad-SPI memory controller, 10/100 Ethernet MAC, dual CAN bus controller, highly robust capacitive sensing, enhanced alpha blending graphics engine, and LESENSE/PCNT enhancements for smart energy meters. These features, combined with ultra-low current active mode and short wake-up time from energy-saving modes, make Giant Gecko Series 1 microcontrollers well-suited for any battery-powered application, as well as other systems requiring high performance and low-energy consumption.

Sleep Current with RTCC as low as
2.1 μA
Active current as low as
80 μA/MHz
