Silicon Labs EFR32FG23 Flex Gecko wireless SoCs

Silicon Labs has released its EFR32FG23 Flex Gecko wireless system-on-chips (SoCs) — sub-GHz wireless solutions that combine long-range RF and energy efficiency with PSA Certified Level 3 security to meet the demand for secure, high-performance, battery-powered IoT products. The SoCs are designed to expand range and power efficiency for multiprotocol sub-GHz connectivity for a wide range of Industrial Internet of Things (IIoT), smart city, and building and home automation applications.

Featuring an integrated power amplifier and good receive sensitivity, the SoCs deliver a range of >1.6 km and 10-plus-year battery performance with fast wake-up times. Together with optimised ultralow transmit and receive radio power (13.2 mA TX at 10 dBm 868 MHz, 3.7 mA RX at 868 MHz) and good RF (up to +20 dBm output power and -125.3 dBm RX at 868 MHz, 2.4 Kbps GFSK), the single-die, multi-core solution is suitable for battery-powered field area network nodes, wireless sensors and connected devices in remote locations.
