•
32-bit ARM Cortex -M4 core at 38.4
MHz maximum operating frequency
Based on the Silicon Labs EFR32MG12 Mighty Gecko SoC, the MGM12P combines an
energy- efficient, multi-protocol wireless SoC with a proven RF/antenna design and in-
dustry leading wireless software stacks. This integration accelerates time-to-market and
saves months of engineering effort and development costs.
• 1 MB of flash and 256 kB of RAM
• ZigBee, Thread, BLE, and multi-protocol
support
• Pin-compatible with MGM111 module
In addition, common software and development tools enable seamless migration from a
module to discrete SoC-based design when the time is right.
• 12-channel Peripheral Reflex System,
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
• Connected Home
• Lighting
• Robust peripheral set and up to 25 GPIO
• Health and Wellness
• Metering
• Building Automation and Security
