April 20, 2022 by Mouser Electronics

This Featured Product Spotlight is part of a video series exploring the specifications, applications, and market context of new products.



The Silicon Labs EFR32FG23 SoC is an ideal solution for sub-GHz Internet of Things appliances in smart home, security, lighting, building automation, and metering applications.

The EFR32FG23 are high-performance sub-GHz radios that provide long-range communications and are not susceptible to 2.4GHz interference. This makes these devices well-suited for secure connected IoT multi-protocol devices requiring high performance and low energy consumption.

The radio provides a high receiver performance with a sensitivity as low as -125.8 dBm. With support for  many modulation formats and protocols, this SoC allows for the use of standard and custom proprietary wireless protocols in the sub-GHz bands.

The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and an integrated power amplifier to enable the next level of secure connectivity for IoT devices.

The EFR32FG23 SoC features an embedded 32-bit ARM® Cortex®-M33 core with a 78 MHz maximum operating frequency, up to 512 kB of flash and 64 kB of RAM, an energy-efficient radio core with low active and sleep currents, and a robust peripheral set with up to 31 GPIO.

The Silicon Labs EFR32FG23 Flex Gecko Wireless SoCs are available in 40-pin and 48-pin Quad Flat No-Lead (QFN) packages with a wide -40°C to +125°C operating temperature range.
