EFM32™ Tiny Gecko 11 32-bit Microcontrollers (MCUs)

Silicon Labs' EFM32™ Tiny Gecko 11 ARM® Cortex®-M0+ based 32-bit microcontrollers (MCUs) offer developers highly integrated functionality for energy-efficient IoT applications. Tiny Gecko 11 continues to build on Silicon Labs leadership in ultra-low power performance and offers new, unique features to simplify development. In addition to ultra-low current consumptions across usable energy modes, the Tiny Gecko MCUs provide sensor interfaces, integrated 8x32 segment LCD and CAN bus controllers, patented wake-on-touch Capacitive Sensing technology, robust security accelerators, and much more. Together, the intersection of energy-efficiency, performance, and easy-to-use developer tools make Tiny Gecko 11 well suited for applications that are looking to do more, with less.

Sleep current with RTCC & RAM as low as
1.3 uA
Active current as low as
37 uA/MHz
