EFR32FG12 Flex Gecko Wireless SoCs

Silicon Labs EFR32FG12 Flex Gecko SoCs combine an energy-friendly MCU with a highly integrated radio transceiver. 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 features. Typical applications include home and building automation and security, metering, electronic shelf labels, industrial automation, and commercial and retail lighting.
