Wireless SoCs enable eco-friendly Zigbee Green Power IoT devices

1 min read

Silicon Labs has unveiled a new family of secure, ultra-low-power Zigbee system-on-chip (SoC) devices that have been designed for eco-friendly IoT products deployed in mesh networks.

The EFR32MG22 (MG22) family expands Silicon Labs’ Zigbee portfolio by delivering the smallest, lowest power SoCs optimized for Zigbee Green Power applications. Based on the company's Wireless Gecko Series 2 platform, the MG22 SoCs are intended for Zigbee devices powered by coin cell batteries or energy-harvesting sources. Target applications include smart home sensors, lighting controls, and building and industrial automation.

Energy-friendly Zigbee Green Power technology can help address environmental concerns by reducing residential, commercial and industrial energy footprints, one IoT device at a time.

Using the same 802.15.4 PHY and MAC of the energy-efficient Zigbee 3.0 protocol, Zigbee Green Power further reduces power consumption by decreasing the amount of data required for wireless transmission. Zigbee Green Power was designed to be a highly efficient protocol enabling IoT devices, whether powered by batteries or by “battery-less” energy harvesting options. Silicon Labs has optimised the MG22 SoCs so as to provide a best-in-class connectivity solution for 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 MG22 SoC solution offers a 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.”

The MG22 SoCs incorporate a high-performance, low-power 76.8 MHz Arm Cortex-M33 core with TrustZone. The SoCs’ combination of ultra-low transmit and receive power (8.2 mA TX at +6 dBm, 3.9 mA RX), 1.4 µA deep-sleep mode power and low-power peripherals provides, what the company claims, is exceptional energy efficiency.
