The Silicon Labs EFM32PG22 (PG22) Gecko microcontrollers combine high performance and low energy consumption with easy-to-use analog capabilities. The Series 2 Gecko microcontrollers are suitable for energy-efficient and space-constrained applications in consumer electronics, appliances, personal hygiene devices, and Internet of Things (IoT) edge and industrial automation devices.
The microcontrollers incorporate a low-power Arm Cortex-M33 core running at up to 76.8 MHz, plus up to 512 KB of flash and 32 KB of RAM. The devices consume 26 μA/MHz in Active Mode at 38.4 MHz and as little as 0.95 µA in DeepSleep mode with 8 KB of RAM retention.
Peripherals include a 12-bit 1 Msps successive approximation (SAR) analog-to-digital converter (ADC), eight-channel DMA controller, digital microphone interface and 32-bit real-time counter. The microcontrollers also feature a comprehensive suite of security features, including secure boot with root of trust and secure loader (RTSL), true random number generator and hardware cryptographic acceleration for AES128/256, SHA-1, SHA-2 (up to 256-bit), ECC (up to 256-bit), ECDH and ECDSA.
The microcontrollers are pin- and software-compatible with the EFR32xG22 wireless SoCs (BG22, MG22 and FG22), allowing designers to leverage a scalable embedded platform to simplify product development. They are supported by the PG22 Dev Kit, which includes four different environmental sensors and stereo PDM microphones, providing a useful platform for the development of energy-friendly electronic devices.
