A dual-band solution for long-range networks, supporting Amazon Sidewalk, Wi-SUN, and more, with AI/ML capabilities for seamless machine learning inference.


Silicon Labs have launched an advanced FG28 System-on-Chip (SoC), a dual-band solution designed for long-range networks, supporting protocols like Amazon Sidewalk, Wireless Smart Utility Network (Wi-SUN), and other proprietary protocols. Boasting dual-band capabilities, the FG28 houses sub-Gigahertz (GHz) and 2.4 GHz Bluetooth LE radios alongside a built-in Artificial Intelligence/Machine Learning (AI/ML) accelerator, empowering seamless machine learning inference. Enabling an array of connectivity options within a single design, the FG28 SoC boasts dual-band capabilities, making it akin to a versatile “Swiss army knife” for modern applications that demand robust connectivity and computing power at the edge. Moreover, the SoC’s potential extends to sprawling ranches, where it serves as livestock trackers and health monitors, enhancing ranch management practices. Notably, the FG28 SoC has several other remarkable features that unlock new applications for sub-Gigahertz devices, making it an exceptional and adaptable solution for a wide range of cutting-edge applications.

The company claims the SoC is the industry’s first integrated Artificial Intelligence/Machine Learning (AI/ML) hardware accelerator within a sub-GHz SoC. It enables on-device machine learning inference for applications such as predictive maintenance warnings and monitoring soil conditions. The SoC offers ample storage with 1024 kB of flash storage and 256 kB of RAM to cater to the memory requirements of various protocols and technology stacks. The SoC provides enhanced trust with Secure Vault support, an energy-efficient radio core, and extensive General Purpose Input/Output (GPIO) pins. SoC offers versatile connectivity for smart cities, irrigation systems, and more, with sub-GHz Wi-SUN and Bluetooth options.
