EFR32FG13 Flex Gecko Proprietary
Protocol SoC Family Data Sheet
The Flex Gecko proprietary protocol family of SoCs is part of the
KEY FEATURES
Wireless Gecko portfolio. Flex Gecko SoCs are ideal for enabling
energy-friendly proprietary protocol networking for IoT devices.
• 32-bit ARM® Cortex®-M4 core with 40
MHz maximum operating frequency
The single-die solution provides industry-leading energy efficiency, ultra-fast wakeup
times, a scalable power amplifier, an integrated balun and no-compromise MCU fea-
tures.
• 512 kB of flash and 64 kB of RAM
• Pin-compatible across EFR32FG families
(exceptions apply for 5V-tolerant pins)
• 12-channel Peripheral Reflex System
enabling autonomous interaction of MCU
peripherals
Flex Gecko applications include:
• Home and Building Automation and Security
• Metering
• Autonomous Hardware Crypto Accelerator
and True Random Number Generator
• Electronic Shelf Labels
• Integrated PA with up to 19 dBm (2.4
GHz) or 20 dBm (Sub-GHz) tx power
• Industrial Automation
• Commercial and Retail Lighting and Sensing
• Integrated balun for 2.4 GHz
• Robust peripheral set and up to 32 GPIO
