Silicon Labs Wireless SoC xG24 Platform



Silicon Labs EFR32BG24

The Silicon Labs EFR32BG24 Wireless SoCs are ideal for IoT wireless connectivity using Bluetooth Low Energy and Bluetooth 6.0 mesh. With AECQ-100 qualification, support for Channel Sounding, and 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 the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. An ARM Cortex®-M33 running up to 78 MHz and up to 1.5 MB of Flash and 256 kB of RAM provides resources for demanding applications while leaving room for future growth.


Bluetooth 6.0 Advanced Features:

Bluetooth 6.0 is a major update over recent, incremental updates, delivering substantial enhancements to audio streaming, device networks, and especially location services. Some of the most significant impacts of these new features are strengthened security and greater accuracy in distance measurement that includes: Bluetooth Channel Sounding, Decision-Based Advertising Filtering and Monitoring Advertisers, ISOAL Enhancement, LL Extended Feature Set and Frame Space Update.
