Introduction

The EFR32MG24 Wireless SoCs are ideal for mesh IoT wireless connectivity using Matter, OpenThread and Zigbee. With key features like high performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator and Secure Vault, IoT device makers can create smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. A Cortex -M33 running up to 78 MHz and up to 1536 kB of Flash and 256 kB of RAM provides resources for demanding applications while leaving room for future growth.
