• Supports multiple wireless protocols including Bluetooth Low Energy, Zigbee, Thread, Matter, and proprietary 2.4 GHz standards.
• Includes hardware security features via Secure Vault and supports direction finding using Angle of Arrival (AoA) and Angle of Departure (AoD).
• Offers extensive peripheral connectivity with 26 GPIOs and serial interfaces such as I2C, SPI, UART, and I2S.

Applications

• Smart home devices and lighting systems requiring mesh networking.
• Medical devices needing secure and reliable wireless connectivity.
• IoT sensors utilizing Thread or Zigbee protocols.
• Bluetooth mesh network nodes for industrial automation.

Procurement Notes

Verify the specific suffix BR indicates reel packaging when sourcing components. Confirm the A010 variant corresponds to the +10 dBm output power specification rather than higher power options. Ensure compatibility with the required QFN-40 footprint during PCB layout. Check for moisture sensitivity levels if storage conditions exceed manufacturer recommendations. Validate that the +125°C operating temperature rating meets environmental requirements.

Selection Notes

Select this model for applications requiring a balance of moderate flash capacity and robust wireless performance. The QFN-40 package suits designs with limited board space compared to larger footprints. Consider the +10 dBm output limit; choose higher power variants if extended range is necessary. The 78 MHz clock speed is sufficient for standard protocol stacks but may require optimization for complex custom algorithms.

Part Context

This component belongs to the EFR32MG24 family, designed for sub-GHz and 2.4 GHz multi-protocol wireless applications. It shares architectural similarities with other MG24 variants but differs in memory size, output power, and package type. The IM40 designation specifically identifies the QFN-40 package configuration within the product line.
