MGM12P Mighty Gecko Multi-Protocol Wireless Mesh Module Data Sheet The Silicon Labs Mighty Gecko Module (MGM12P) is a fully-inte- KEY FEATURES grated, certified module, enabling rapid development of wireless mesh networking solutions. 32-bit ARM Cortex -M4 core with 40 MHz maximum operating frequency Based on the Silicon Labs EFR32MG12 Mighty Gecko SoC, the MGM12P combines an 1 MB of flash and 256 kB of RAM energy- efficient, multi-protocol wireless SoC with a proven RF/antenna design and in- ZigBee, Thread, BLE, and multi-protocol dustry leading wireless software stacks. This integration accelerates time-to-market and support saves months of engineering effort and development costs. Pin-compatible with MGM111 module In addition, common software and development tools enable seamless migration from a 12-channel Peripheral Reflex System, module to discrete SoC-based design when the time is right. Low-Energy Sensor Interface & Multi- channel Capacitive Sense Interface MGM12P can be used in a wide variety of applications: Integrated PA with up to +17 dBm transmit power IoT Multi-Protocol Devices Robust peripheral set and up to 25 GPIO Connected Home Lighting Health and Wellness Metering Building Automation and Security Core / Memory Clock Management Energy Management Other High Frequency High Frequency Voltage CRYPTO Crystal Voltage Monitor RC Oscillator Regulator TM Oscillator ARM Cortex M4 processor Memory CRC with DSP extensions and FPU Protection Unit Auxiliary High Low Frequency DC-DC Frequency RC Power-On Reset RC Oscillator Converter True Random Oscillator Number Generator Low Frequency Ultra Low Flash Program Debug Interface LDMA Brown-Out RAM Memory Crystal Frequency RC SMU Memory with ETM Controller Detector Oscillator Oscillator 32-bit bus Peripheral Reflex System Antenna Radio Transceiver Serial I/O Ports Timers and Triggers Analog I/F Interfaces Integrated Chip ADC DEMOD External Antenna USART Timer/Counter Protocol Timer Interrupts Analog Comparator Low Energy General Low Energy PGA IFADC I Watchdog Timer TM UART Purpose I/O Timer External Antenna LNA IDAC U.FL Connector RF Frontend Real Time AGC Capacitive Sense 2 PA I C Pin Reset Pulse Counter Counter and Q Frequency Calendar Synthesizer VDAC Matching Low Energy MOD Pin Wakeup Cryotimer Sensor Interface Op-Amp Lowest power mode with peripheral operational: EM0Active EM1Sleep EM2Deep Sleep EM3Stop EM4Hibernate EM4Shutoff silabs.com Building a more connected world.
