EFR32FG1 Flex Gecko Proprietary
Protocol SoC Family Data Sheet
The Flex Gecko proprietary protocol family of SoCs is part of the
Wireless Gecko portfolio. Flex Gecko SoCs are ideal for enabling
energy-friendly proprietary protocol networking for IoT devices.
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.
Flex Gecko applications include:
• Commercial and Retail
• Home and Building Automation and Security
• Metering
• Electronic Shelf Labels
• Industrial Automation
