Silicon Labs has a new family of secure, ultra-low-power Zigbee SoC devices created for eco-friendly IoT products deployed in mesh networks. The EFR32MG22 (MG22) family expands Silicon Labs’ Zigbee portfolio by producing the smallest, lowest power SoCs optimised for Zigbee Green Power applications. Based on the company's Wireless Gecko Series 2 platform, the MG22 SoCs are an excellent choice for Zigbee devices powered by coin cell batteries or by energy-harvesting sources. Targeted applications incorporate lighting controls, smart home sensors, and building and industrial automation.

Energy-friendly Zigbee Green Power technology can assist address environmental concerns by reducing commercial, industrial and residential energy footprints, one IoT device at a time. Employing the same 802.15.4 PHY and MAC of the already energy-efficient Zigbee 3.0 protocol, Zigbee Green Power further decreases power consumption by reducing the amount of data needed for wireless transmission. From its inception, Zigbee Green Power was created to be a highly efficient protocol enabling IoT devices, whether powered by batteries or by 'battery-less' energy harvesting options. The company optimised the new MG22 SoCs to offer a best-in-class connectivity solution for these challenging, power-sensitive wireless applications.

“As the leading Zigbee provider, Silicon Labs is uniquely positioned to lead the way in Zigbee Green Power mesh networking solutions,” said Matt Johnson, senior vice president and general manager of IoT products at Silicon Labs. “Our new MG22 SoC solution offers an industry-leading combination of energy efficiency, security capabilities, wireless performance, and software tools and stacks to meet the growing market demand for eco-friendly, ultra-low-power IoT products.”
