Wireless SoCs for sub-GHz IoT applications

29-11-2021 | Mouser Electronics | Semiconductors

Mouser now stocks the EFR32FG23 Flex Gecko wireless SoCs from Silicon Labs. The devices sub-GHz wireless solutions combine long-range RF and energy efficiency with PSA Certified Level 3 security to satisfy the need for secure, high-performance, battery-powered IoT products.

The SoCs extend the range and power efficiency for multiprotocol sub-GHz connectivity for a broad range of IIoT, smart city, and building and home automation applications. Providing an integrated power amplifier and outstanding receive sensitivity, the SoCs give an increased range of 1+ miles and excellent 10-plus-year battery performance with fast wakeup times. Together with optimised ultra-low transmit and receive radio power (13.2mA TX at 10dBm 868MHz, 3.7mA RX at 868MHz) and best-in-class RF (up to +20dBm output power and -125.3dBm RX at 868MHz, 2.4kbps GFSK), this single die, multi-core solution is excellent for battery-powered field area network nodes, wireless sensors, and connected devices in remote locations.

The SoCs are supported by a suite of development tools, incorporating the company's FG23 868MHz-915MHz +14dBm Development Kit. This compact, feature-packed development platform kit offers a fast path to develop and prototype sub-GHz loT products. It incorporates support for the FG23's onboard segment LCD controller and other key features, such as the Low Energy Sensor Interface and pulse counter.
