Silicon Labs Unveils World’s First Secure Sub-GHz SoCs with Long-Range RF

Article By : Silicon Labs

Silicon Labs has launched new sub-1-GHz SoCs that combine long-range RF and energy efficiency with certified Arm PSA Level 3 security.

Silicon Labs has launched new sub-1-GHz (sub-GHz) SoCs, delivering the world’s first sub-GHz wireless solutions that 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 award-winning Series 2 platform, EFR32FG23 (FG23) and EFR32ZG23 (ZG23) system-on-chip (SoC) solutions 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 solutions 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.”

Unlocking Efficiencies with 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 SoC solutions offer an optimized combination of ultra-low transmit and receive radio power (13.2mA TX at 10dBm, 4.2mA RX at 920MHz) and best-in-class RF (+20dBm output power and -125.3dBm RX at 868MHz, 2.4kbps GFSK), making it possible for IoT end nodes to achieve more than 1 mile wireless range while operating on a coin cell battery for over 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.

The 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.

FG23

FG23 targets Amazon Sidewalk, industrial IoT (IIoT), smart city, building and home automation markets that often require battery powered end nodes with extended wireless communication range capabilities. The FG23 wireless SoC solution provides a flexible antenna diversity feature to enable best-in-class wireless link budget (-111.2dBm RX at 920MHz, 50kbps GFSK). Advanced wireless, coupled with FG23’s low active current (26µA/MHz) and sleep mode (1.2µA) make it an ideal solution for battery-powered field area network nodes, wireless sensors and connected devices in difficult to reach locations.

ZG23

ZG23 enhances Z-Wave Wireless by adding Secure Vault and offers the same industry-leading RF, power performance as FG23. Supporting Z-Wave Long Range and Mesh, these are the first SoCs to be optimized for both end devices and gateways and can also support all FG23 protocols. The ZG23 wireless solution targets smart home, hotel and multi-dwelling unit (MDU) markets. Ultra-compact ZG23-based SiP modules (ZGM230S), supporting Z-Wave only, will also be made available to simplify development and speed-time-to-market.
