Silicon Labs 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.

Silicon Labs offer EFM32PG12 Pearl Gecko MCUs which combine very low active current consumption, enhanced sleep mode capabilities, and integrated security features. This enables the next generation of secure, battery-operated IoT products. A large 1MB flash with dual-bank architecture and in-field update capability enables even richer applications that can be updated after product deployment.
