The Mighty Gecko family of SoCs is ideal for designing energy-friendly wireless connected IoT devices. Part of the Wireless Gecko portfolio, the Mighty Gecko is designed for 2.4GHz 802.15.4 Zigbee and Thread networks. The family also includes support for Bluetooth Low Energy and 2.4/subGHz based proprietary protocols which can be used for simplified commissioning and additional protocol functionality. The single-die solution provides industry-leading energy efficiency, ultra-fast wakeup times, a scalable power amplifier, and no-compromise MCU features which make it well suited for battery operated applications or high performance systems.

The EFR32MG12 combines Silicon Labs’ energy-friendly Gecko MCU technology with a multiprotocol 2.4 GHz RF transceiver in a single-die solution with scalable memory options (up to 1 MB flash and up to 256 kB RAM). Hallmarks of Gecko technology include well-architected energy modes, ultra-fast wake-up/sleep transitions, and the Peripheral Reflex System (PRS), enabling autonomous operation of low-power peripherals while the MCU core sleeps. Based on an ARM Cortex-M4 processor with powerful floating point and DSP capabilities, the Gecko MCU consumes only 63 µA/MHz in active mode. The Wireless Gecko SoCs also integrate a software-programmable power amplifier (PA) and balun to reduce bill of materials (BOM) cost and design complexity while providing scalable output power ranging from -30 dBm up to +19 dBm for applications requiring long-range connectivity.

OpenThread running on the EFR32MG12 is a Thread Certified Component.

Wireless Gecko Series 2 devices are the next evolution of Wireless Gecko devices from Silicon Labs. Series 2 is designed to increase processing capability, improve RF performance and lower active current, while providing the higher levels of security required for tomorrow’s IoT products.

The EFR32MG21 Series 2 device is a 2.4 GHz wireless SoC optimized for line-powered Zigbee, Thread and Bluetooth mesh applications, including connected lighting, gateways, voice assistants and smart metering. An 80 MHz ARM® Cortex®-M33 core provides plenty of processing capability while a dedicated security core provides faster encryption, secure boot loading, and debug access control. With better than -104 sensitivity for both 802.15.4 and Bluetooth Long Range and up to +20 dBm output power, the EFR32MG21 provides a robust RF link to ensure reliable communications. Series 2 uses the same tools as Series 1, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps, and Silicon Labs patented network analyzer.
