EFR32MG24A410F1536IM48-BR

Overview

The EFR32MG24A410F1536IM48-BR is a Bluetooth System on Chip from the MG24 series, featuring an ARM Cortex-M33 core with a maximum clock frequency of 78 MHz. It integrates 1536 kB of Flash memory and 256 kB of RAM. The device supports 2.4 GHz operation with a maximum data rate of 2 Mbps, delivering +10 dBm output power and -94.4 dBm sensitivity. Operating within a voltage range of 1.71 V to 3.8 V, it functions between -40°C and +125°C in a QFN-48 package.

Feature Summary

• Integrates an ARM Cortex-M33 processor for efficient wireless control
• Provides high RF performance with +10 dBm output power
• Includes substantial onboard memory for complex application storage

Applications

• Smart home devices requiring robust Bluetooth connectivity
• Industrial sensor nodes operating in extreme temperatures
• Wearable electronics needing compact form factors

Procurement Notes

Verify the specific suffix BR indicates reel packaging when sourcing components. Confirm the QFN-48 footprint matches your PCB design requirements. Ensure compatibility with the 1.71 V to 3.8 V supply range for your target application. Cross-reference the datasheet for moisture sensitivity levels and handling instructions prior to assembly.

Selection Notes

Choose this model when 1536 kB of program storage and 256 kB of RAM are required for complex firmware. Select the +10 dBm variant if extended range is unnecessary compared to higher power options. The QFN-48 package suits designs prioritizing moderate pin counts with surface-mount constraints. Consider thermal management capabilities given the +125°C operational limit.

Part Context

This component belongs to the Silicon Labs EFR32MG24 family, designed for Bluetooth applications. It utilizes a silicon-based technology node and supports standard interfaces like I2C. The part is categorized under Wireless & RF Integrated Circuits, targeting markets demanding reliable short-range wireless communication with integrated processing capabilities.

Replacement Considerations

EFR32MG24A420F1536IM48-BR offers identical memory and core specifications but provides +20 dBm output power instead of +10 dBm.
