The EFR32FG23 (FG23) and EFR32ZG23 (ZG23) system-on-chip (SoC) sub-GHz wireless solutions 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. The devices, says the company, 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," says 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."
The FG23 and ZG23 are offered as providing 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. The 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, says the company, 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
