EFM32 Pearl Gecko MCUs

Silicon Labs Pearl Gecko 32-bit microcontroller (MCU) family provides a powerful 32-bit ARM® Cortex®-M4 and a range of peripherals. The peripherals include a unique cryptographic hardware engine that supports AES, ECC, and SHA. The Pearl Gecko 32-bit MCUs also feature an ultra-low current active mode and short wake-up time from energy-saving modes. The Pearl Gecko MCUs are ideal for battery-powered applications and other systems requiring high performance and low energy consumption.
