Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The EFR32MG22 Series 2 Wireless SoC, the EFR32MG22E224F512IM32 is designed with a strong focus on energy efficiency. It contains a 76.8 MHz ARM Cortex-M33 core that delivers superior processing power, while its integrated security features allow for fast encryption. The device comes with 512 kB of flash memory, 32 kB of RAM, and is packaged in QFN32.

The EFR32MG22E224F512IM32 has a maximum power output of up to 6 dBm and excellent receiving sensitivity: The -102.1 (250 kbit/s OQPSK) dBm provides a robust RF link to ultra-low-power Zigbee terminal nodes, including green power applications, for reliable communication and industry-leading energy efficiency.

The EFR32MG22E224F512IM32 device uses the same tools as the EFR32MG Series 1 to provide easy migration and reduce time to market with development kits, SDKS, mobile applications and our patented network analyzer.
