Silicon Labs' EFM32PG22 32-bit microcontroller (MCU) family is a pin and software compatible MCU-only version of the award-winning EFR32xG22 wireless SoC platform (BG22, MG22, and FG22). It offers developers a drop-in upgrade path to Bluetooth® Low Energy (BLE), Zigbee®, or proprietary (2.4 GHz) wireless connectivity. PG22 32-bit MCUs are ideal for enabling a wide range of ultra-low-power and high-performance embedded IoT applications. The highly efficient PG22 offers a 76.8 MHz Cortex®-M33 with rich analog and communication peripherals providing a compact, highly integrated MCU for consumer and industrial markets. The PG22 also introduces the availability of enhanced device security, including a hardware accelerated cryptography engine, a true random number generator, secure boot with root of trust, and secure debug with lock and unlock.
