First secure sub-GHz SoCs with over a mile range
With 10+ year battery life, new Series 2 paltform SoCs support Amazon Sidewalk, mioty, Wireless M-Bus, Z-Wave and proprietary IoT networks.

Silicon Labs has announced new sub-1-GHz (sub-GHz) SoCs that are the first sub-GHz wireless devices to combine long-range RF and energy efficiency with certified Arm PSA Level 3 security to meet the global demand for high-performance, battery-powered IoT products. Expanding the company’s Series 2 platform, EFR32FG23 (FG23) and EFR32ZG23 (ZG23) SoCs provide developers with flexible, multiprotocol sub-GHz connectivity options supporting a wide range of modulation schemes and advanced wireless technologies, including Amazon Sidewalk, mioty, Wireless M-Bus, Z-Wave and Proprietary IoT networks.

“This new evolution of our Series 2 platform is answering the ever-increasing demands for highly-integrated, long range wireless connectivity to enable cities, industries and homes to operate more efficiently and sustainably,” said Matt Johnson, president of Silicon Labs. “Silicon Labs’ new secure, ultra-low-power sub-GHz SoCs extend wireless communication beyond one-mile, thus expanding the boundaries for developers who need scalable high-performance wireless to drive the transformative potential of the IoT.”

According to the U.S. Energy Information Administration, 60% of the world’s energy usage comes from industrial and commercial applications and residential energy consumption accounts for 21%. Smart grid technology, building and home automation IoT systems can positively impact global sustainability and drastically reduce energy consumption. Silicon Labs designed the FG23 and ZG23 SoCs to enable the next generation of secure IoT products to accelerate sustainability and energy efficiency initiatives.

The new FG23 and ZG23 wireless SoCs offer an optimized combination of ultra-low transmit and receive radio power (13.2 mA TX at 10 dBm, 4.2 mA RX at 920 MHz) and best-in-class RF (+20 dBm output power and -125.3 dBm RX at 868 MHz, 2.4 kbps GFSK), making it possible for IoT end nodes to achieve 1+ mile wireless range while operating on a coin cell battery for 10+ years. These SoCs also leverage Secure Vault™, certified PSA Level 3, enabling developers to safeguard IoT products against software and hardware attacks which can compromise intellectual property, ecosystems and brand trust. FG23 and ZG23 SoCs enable developers to create IoT products that enhance the efficiency and performance of a wide range of applications including smart infrastructure, metering, environmental monitoring, connected lighting, industrial controls, electronic shelf labels (ESL), building and home automation
