Silicon Labs CSP Package EFM32™ Wonder Gecko 32-bit MCUs
Silicon Labs CSP Package EFM32™ Wonder Gecko 32-bit MCUs are based on the ARM® Cortex®-M4 core, which provides a complete 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 new CSP packages offer energy-friendly MCU in 60% smaller packaging enabling a breakthrough in industrial design for small portable devices.
Within portable devices, the electronics and battery often dictate the physical size of the industrial design, and these new products help with both aspects. EFM32 energy efficiency allows you to select a smaller battery, and the new CSP package allows your PCB to be smaller. These MCUs incorporate highly differentiated Gecko technology to minimize energy consumption, including a flexible range of standby and sleep modes and intelligent peripherals that allow designers to implement many functions without CPU wake-up and ultra-low standby current. The Silicon Labs Wonder Gecko with an energy-friendly Cortex-M4 MCU comes with the lowest active and standby power consumption.
