Silicon Labs’ FG23L wireless SoC will be generally available this month for sub-GHz IoT and higher-volume applications.

Developer kits for this latest addition to the Texas company’s Series 2 portfolio are available now.

The FG23L is said to deliver secure long-range connectivity at a fraction of the cost.

“The FG23L extends Silicon Labs’ proven sub-GHz leadership into the high-volume, cost-sensitive segment of the market,” said Ross Sabolcik, senior vice president at Silicon Labs. “By delivering the best-in-class combination of range, efficiency and security at the industry’s most competitive price-performance, we’re enabling customers to bring more connected devices to market faster and at lower cost than ever before.”

As demand grows for long-range, cost-optimised wireless IoT in industrial automation, smart cities and building automation, the FG23L is purpose-built to help users meet these needs with higher performance and lower system cost. Where competitive offerings often force trade-offs between range, security or efficiency, the FG23L is said to deliver on all three.

With a link budget of about 146dB, it provides up to twice the range of comparable devices. Its combination of +20dBm transmit power, high receiver sensitivity and low power consumption enables reliable connectivity and over ten years of battery life, critical for large-scale IoT deployments where device longevity and total cost of ownership matter.

It integrates a 78MHz Cortex-M33 core, dual-core wireless architecture and Secure Vault mid security to deliver compute performance, connectivity and protection against evolving security threats. Developers benefit from a rich peripheral set, 23 GPIOs and streamlined design tools, including Simplicity Studio 5 and the Radio Configurator, which accelerate development and reduce complexity across global sub-GHz bands.

This combination of performance, energy efficiency and affordability gives users the ability to scale IoT deployments faster and more cost-effectively. From industrial sensors, building automation and smart city infrastructure to agricultural IoT and electronic shelf labels, it empowers manufacturers to design connected products that compete more effectively in cost-sensitive markets.

Developers also have a seamless migration path from FG23L to FG23 and other sub-GHz parts from Silicon Labs in case they are looking for more memory, more features, higher performance or lower power.

The EFR32FG23L wireless SoCs (www.silabs.com/wireless/proprietary/efr32fg23l-sub-ghz-wireless-socs) will be generally available on September 30, and supporting development kits are now available worldwide through Silicon Labs’ distribution partners and www.silabs.com.
