EFR32FG25 Gecko Wireless SoC Family
Data Sheet
The EFR32FG25 Gecko SoC is an ideal solution for sub-GHz Wi-SUN applications for
metering, lighting, and distribution automation.
KEY FEATURES
The high-performance sub-GHz radio provides long range and is not susceptible to 2.4
GHz interference from technologies like Wi-Fi.
• 32-bit ARM® Cortex®-M33 core with 97.5
MHz maximum operating frequency
• Up to 1920 kB of flash and 512 kB of RAM
The single die, multi-core solution, provides industry leading security, high throughput,
and an integrated power amplifier to enable the next level of secure connectivity for IoT
devices.
• Wi-SUN Multi-rate OFDM, FSK, and O-
QPSK modulations
• Integrated PA with up to 16 dBm (Sub-
GHz) TX power
EFR32FG25 applications include:
• Robust peripheral set and up to 37 GPIO
• Operation up to 125 °C
• Smart Electric Metering
• Street Lighting
• Distribution automation
• Industrial applications
• Municipal infrastructure
