Silicon Labs EFM32™ Wonder Gecko 32-bit Microcontrollers

Silicon Labs EFM32™ Wonder Gecko 32-bit Microcontrollers are MCUs based on the ARM® Cortex®-M4 core, which provides a full DSP instruction set and includes a hardware FPU for faster computation performance. Wonder Gecko MCUs feature up to 256kB of flash memory, 32kB of RAM and CPU speeds up to 48MHz. These MCUs incorporate highly differentiated Gecko technology to minimize energy consumption, including a flexible range of standby and sleep modes, intelligent peripherals that allow designers to implement many functions without CPU wake-up and ultra-low standby current. With the lowest active and standby power consumption, the Wonder Gecko is the world's most energy friendly Cortex-M4 MCU.
