Highly secure sub-GHz SoCs

25 August 2021 Telecoms, Datacoms, Wireless, IoT

Delivering what it claims as the world's first sub-GHz wireless solutions to combine long-range RF and energy efficiency with certified Arm PSA Level 3 security, Silicon Labs has unveiled a lineup of new SoCs (systems-on-chip) 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 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.

The chips offer an optimised combination of ultra-low transmit and receive radio power (13,2 mA TX at 10 dBm, 4,2 mA RX at 920 MHz) and high RF performance (+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 a wireless range of 1,6 km or more 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.
