Pearl Gecko microcontrollers feature a 32-bit ARM Cortex-M4 processor core. They offer a wide array of peripherals and a cryptographic hardware engine supporting AES, ECC, and SHA. With low current active mode and short wake-up times, Pearl Gecko microcontrollers are perfect for battery powered applications and other low-energy systems. Two versions are offered with different MCU specifications and different peripherals.
