EFR32xG13 Wireless Gecko Reference Manual
The Wireless Gecko portfolio of SoCs (EFR32) include MightyGecko (EFR32MG13), Blue Gecko (EFR32BG13), and FlexGecko (EFR32FG13) families. With support for Zigbee®, Thread,Bluetooth Low Energy (BLE) and proprietary protocols, the Wire-less Gecko portfolio is ideal for enabling energy-friendly wireless networking for IoT devices.The single-die solution provides industry-leading energy efficiency, ultra-fast wakeup times, a scalable high-power amplifier, an integrated balun and no-compromise MCU features.
KEY FEATURES：
• 32-bit ARM® Cortex-M4 core with 40 MHz maximum operating frequency
• Scalable Memory and Radio configuration options available in several footprint compatible QFN packages
• 12-channel Peripheral Reflex System enabling autonomous interaction of MCU peripherals
• Autonomous Hardware Crypto Accelerator and True Random Number Generator
• Integrated balun for 2.4 GHz andintegrated PA with up to 19 dBm transmit power for 2.4 GHz and 20 dBm transmit power for Sub-GHz radios
• Integrated DC-DC with RF noise mitigation
• Integrated PLFRCO eliminates external 32kHz crystal for BLE applications
