September 15, 2025 /SemiMedia/ — Silicon Labs announced its new FG23L wireless system-on-chip (SoC) will be generally available on September 30, with developer kits already shipping. The device is designed to extend the company’s presence in sub-GHz IoT by offering long-range, secure connectivity at a competitive cost.

The FG23L targets high-volume applications in industrial automation, smart cities and building management, combining +20 dBm transmit power, high receiver sensitivity and ultra-low power operation. With a link budget of about 146 dB, the SoC delivers up to double the range of comparable devices and supports over a decade of battery life.

Built on a 78 MHz Cortex-M33 core with dual-core wireless architecture and Secure Vault™ Mid protection, the FG23L strengthens compute performance and safeguards against security threats. Developers can leverage 23 GPIOs, a broad peripheral set, and design tools such as Simplicity Studio 5 and the Radio Configurator to streamline development.

The combination of efficiency, performance and affordability positions FG23L for deployment in sensors, agricultural IoT, electronic shelf labels and other cost-sensitive markets. Customers seeking more memory or features can migrate to FG23 and other Silicon Labs sub-GHz parts.
