The EFR32MG22 (hereinafter MG22) SoC family is based on Silicon Labs' Wireless Gecko Series 2 platform and is suitable for designing Zigbee devices that use coin cell batteries or energy harvesting power.
Zigbee Green Power technology was designed with protocols in mind that allow IoT devices to run on battery power or without a battery using energy harvesting technology.
Zigbee Green Power, which uses 802.15.4 PHY and MAC such as the Zigbee 3.0 protocol, reduces power consumption by reducing the amount of data required for wireless transmission.
Silicon Labs has optimized the MG22 SoC to provide connectivity solutions for power-sensitive wireless applications. The MG22 SoC integrates a high-performance, low-power 76.8MHz Arm Cortex-M33 core and TrustZone security technology.
Target applications for the MG22 SoC, which consumes 8.2mA of current when transmitting and 3.9mA when receiving at +6dBm and only 1.4µA of current in deep sleep mode, include smart home sensors, lighting control, and building and industrial automation.
