EFM32™ Tiny Gecko 32-bit Microcontroller

 Our energy-efficient EFM32™ Tiny Gecko microcontrollers (MCUs) offer low-power benefits such as brown-out, full RAM, and register retention. Available in packages as small as 4x4 mm, our Tiny Gecko 32-bit MCUs consume as little as 150 μA/MHz in run mode, and as little as 1 μA with a real-time counter running, making them ideal for energy-sensitive applications. Featuring the industry-standard ARM®Cortex®-M3 processor, the Tiny Gecko MCU family provides autonomous and energy-efficient peripherals and high overall chip and analog integration.

Sleep current with RTC as low as
1.0 μA
Active current as low as
150 μA/MHz
