EFR32MG22E224F512IM40-CR

Overview

The EFR32MG22E224F512IM40-CR is a Mighty Gecko System on Chip (SoC) from Silicon Labs, designed for 2.4 GHz wireless applications. It features an ARM Cortex-M33 core operating at 76.8 MHz and supports Bluetooth Mesh networking protocols. The device integrates 512 kB of flash memory and 32 kB of RAM within a QFN-40 package. Key RF specifications include a maximum output power of 6 dBm and a receive sensitivity of -106.7 dBm. It operates on a supply voltage range of 1.71 V to 3.8 V, with current consumption of 8.2 mA during transmission and 3.6 mA during reception.

Feature Summary

• Integrates an ARM Cortex-M33 processor for efficient multiprotocol networking and fast startup capabilities in IoT devices.
• Supports 2.4 GHz operation with up to 6 dBm output power, suitable for mesh network topologies.
• Includes integrated security features and multiple GPIOs for flexible peripheral connectivity.

Applications

• Bluetooth Mesh lighting systems
• Smart home sensor nodes
• Industrial IoT monitoring devices

Procurement Notes

Verify the specific suffix 'CR' indicates the reel packaging format as documented by the manufacturer. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the QFN-40 exposed pad mounting requirements are compatible with your PCB design guidelines. Cross-reference the datasheet revision to confirm electrical characteristics match your system design constraints.

Selection Notes

Select this model when a 2.4 GHz solution with Bluetooth Mesh support is required. The 512 kB flash capacity provides sufficient storage for complex application logic compared to lower-tier variants. Consider the 6 dBm output power adequate for short-range indoor deployments. The QFN-40 package offers a compact footprint suitable for space-constrained designs requiring surface mount technology.

Part Context

This component belongs to the EFR32MG22 Mighty Gecko family, which targets energy-efficient wireless applications. It shares architectural similarities with other Blue Gecko and Flex Gecko series but is optimized specifically for 2.4 GHz mesh networks. The MG22 series emphasizes low power consumption while maintaining robust processing capabilities for connected home and industrial use cases.

Replacement Considerations

Direct substitutes within the same family include EFR32MG22E224F512IM40-C without the reel suffix if tape-and-reel packaging is not strictly required. For higher performance needs, consider the EFR32BG22 series for Bluetooth LE focus or EFR32FG23 for Sub-GHz frequencies. Verify pin compatibility and software library support before swapping between different Gecko series generations.
