EFR32MG1 Series 1 Mesh Networking Wireless SoCs for Zigbee and Thread

EFR32MG1 SoCs are ideal for designing energy-friendly wireless connected IoT devices. Part of the Wireless Gecko portfolio, EFR32MG1 devices support Zigbee and Thread wireless connectivity and include Bluetooth low energy and 2.4 GHz and sub-GHz proprietary protocol support. The single-die solution provides industry-leading energy efficiency, ultra-fast wakeup times, a scalable power amplifier and no-compromise microcontroller (MCU) features. The devices are well suited for mains powered mesh applications including lighting, gateways and voice assistants, as well as other systems requiring high performance and low energy consumption. To future proof designs, we recommend migrating to EFR32MG devices with more Flash and memory due to the evolution of Zigbee and Thread (Open Thread) protocols. 

  • EFR32MG13 for battery powered Zigbee or Thread applications
  • EFR32MG12 for Zigbee, Thread and multiprotocol applications.
  • EFR32MG21 for mains powered mesh applications including lighting, gateways and voice assistants.
