Our EFM32WG 32-bit microcontrollers (MCUs) have low active and standby power consumption. The 32-bit microcontroller family includes 60 devices based on the ARM® Cortex®-M4 core, providing a full DSP instruction set and hardware FPU for faster computation performance.
The EFM32WG MCU family includes a flexible range of standby and sleep modes and intelligent peripherals to minimize energy consumption. This diverse set of peripherals and modes allows designers to implement many application functions using ultra-low standby current and without CPU wake-up.
