Mouser Electronics is now offering the EFR32xG22E wireless Gecko system-on-chip (SoC) series from Silicon Labs. The EFR32xG22E represents Silicon Labs’ most energy-efficient wireless SoC to date, specifically designed to function within the ultra-low-power parameters essential for battery-free energy harvesting. These SoCs enable the development of Bluetooth Low Energy (LE), 802.15.4-based, or proprietary 2.4GHz wireless devices for IoT applications that harness energy from external sources.
The Silicon Labs EFR32xG22E wireless Gecko SoC family, now available through Mouser, includes three variants: the EFR32BG22E, EFR32MG22E, and EFR32FG22E. Each variant features an integrated Arm Cortex M4 microcontroller and a high-performance 2.4GHz radio. These SoCs are particularly suited to devices requiring immediate activation and efficient power management, boasting an EM4 wake-up time of 1.83 milliseconds and power consumption as low as 16.6 microjoules (µJ). Additionally, the SoCs support multiple power sources and power management devices, enabling users to explore new battery technologies, such as supercapacitors.
The EFR32BG22E wireless SoC facilitates Bluetooth 5 networking in IoT devices that require quick startup times, such as asset tags, beacons, consumer electronics, and Bluetooth Mesh low-power nodes. It also supports Bluetooth 5 direction-finding. The EFR32MG22E SoC is tailored for Zigbee green power applications, including home automation, lighting and building controls, and smart building sensors.
This Zigbee-optimised SoC incorporates a 12-channel peripheral reflex system, allowing for autonomous interaction among MCU peripherals, which reduces both latency and power consumption. The EFR32FG22E proprietary wireless 2.4 SoC features RFSense technology and offers enhanced energy efficiency and extended lifespan for products with limited battery resources, making it an ideal single-die solution for electronic shelf labels, home and building automation, and commercial lighting.
The EFR32xG22E wireless Gecko SoCs from Silicon Labs are supported by the xG22 Development Tools, including the EFR32xG22E wireless Gecko radio boards and starter kit. These tools equip developers with all they need to evaluate the EFR32xG22E wireless Gecko SoCs and build scalable wireless IoT applications.
