Silicon Labs has launched a family of wireless SoCs and MCUs aimed at supporting AI-based applications on smart home devices and Matter over Thread. The xG26 family is equipped with double the Flash and RAM of its previous devices and consists of the multiprotocol MG26 SoC, the Bluetooth LE BG26 SoC, and the PG26 MCU.

All three are designed to future-proof smart home IoT against demanding emerging applications such as Matter.

The xG26 family can be equipped with:

  • Doubled Flash, RAM, and GPIO capacity compared to the xG24 device family, allowing IoT device builders to develop advanced edge applications. It also has double the number of general-purpose input/output (GPIO) pins as the xG24, meaning that device builders can connect it to twice as many peripherals for better system integration.
  • Higher performance compute in a multicore format with an ARM Cortex-M33 CPU and dedicated cores for the radio and security subsystems, helping to free up the main core for customer applications.
  • Embedded AI/ML hardware acceleration, enabling up to 8x faster processing of machine learning algorithms using 1/6th the power.
  • Using the Silicon Labs Custom Part Manufacturing Service, xG26 devices can be hard-coded with customer-designed security keys and other features in the fabrication process, hardening them against vulnerabilities.
  • 2.4 GHz wireless connectivity for protocols including Matter, Zigbee, OpenThread, Bluetooth Low Energy, Bluetooth Mesh, Proprietary, and Multiprotocol.
