EFR32MG1 Mighty Gecko SoC with
Integrated Serial Flash Data Sheet
The Mighty Gecko family of SoCs is part of the Wireless Gecko
multi-protocol portfolio.
The EFR32MG1x632 and EFR32MG1x732 Mighty Gecko ICs integrate a 512 kB serial
flash in the package to support over the air updates. This 5x5 QFN32 package is ideal
for space constrained products that need to support ZigBee, Thread, BLE and propriet-
ary networks.
Mighty Gecko applications include:
• Connected Home
• Lighting
• Home and Building Automation and Security
KEY FEATURES
• 32-bit ARM® Cortex®-M4 core with 40
MHz maximum operating frequency
• Scalable Radio configuration options
available in QFN32 package
• 512 kB co-packaged serial flash for over
the air updates
• 12-channel Peripheral Reflex System
enabling autonomous interaction of MCU
peripherals
• Autonomous Hardware Crypto Accelerator
and Random Number Generator
• Integrated 2.4 GHz balun and PA with up
to 19.5 dBm transmit power
• 125 °C operating temperature ideal for
connected lighting applications
