EFM32 Pearl Gecko Family of 32-Bit MCUs

Silicon Labs’ Pearl Gecko family of 32-bit MCUs are designed to balance performance and power consumption for battery-powered IoT, health, and fitness, and home and factory automation devices.  

Pearl Gecko MCUs are based on an ARM® Cortex®-M4 with DSP instructions, a crypto engine that supports AES, ECC, and SHA, and up to 1MB of dual port flash program memory that supports read-while-write functionality, enabling in-field updating.  

The devices have ultra-low power consumption and short wake-up times to maximize performance and battery life, and a low-energy sensor interface for autonomous sensor monitoring while the MCU is in deep sleep mode.

  • ARM® Cortex®-M4 @ 40 MHz
    • Active mode: 64 µA/MHz
    • Deep sleep: 1.5 µA to 2.1 µA
  • Up to 65 GPIOs
  • Hardware crypto: AES 128/256-bit keys, ECC, SHA-1 and SHA-2, TRNG
  • Packages: QFN-32, QFN-48, BGA-125
