Overview

The EFR32MG24A010F1536IM40-B is an RF System on a Chip from the Silicon Labs MG24 series, designed for 2.4 GHz wireless applications. It integrates an ARM Cortex-M33 core operating at a maximum clock frequency of 78 MHz with 1536 kB of Flash program memory and 192 kB of RAM. The device supports Bluetooth and Zigbee protocols with a maximum data rate of 2 Mbps. Key electrical parameters include a transmit output power of +10 dBm and a receive sensitivity of -94.8 dBm. It operates within a supply voltage range of 1.71 V to 3.8 V, with typical current consumption of 4.4 mA during reception and 19.1 mA during transmission. The component is housed in a QFN-48 package and supports an industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates an energy-efficient ARM Cortex-M33 microcontroller with a high-performance 2.4 GHz radio transceiver for low-power mesh networking.
• Includes Secure Vault hardware security features to protect cryptographic keys and sensitive data within the SoC architecture.
• Supports multiple wireless standards including Bluetooth and Zigbee, enabling versatile connectivity for IoT ecosystems.

Applications

• Smart home automation devices
• Wireless lighting controls
• Medical monitoring equipment

Procurement Notes

Verify the specific suffix B indicates the tray packaging configuration when sourcing. Confirm that the QFN-48 package dimensions align with your PCB footprint requirements. Ensure the selected variant meets the required industrial temperature rating of +125°C for your application environment. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Choose this model when a balance of moderate memory capacity and standard transmit power is required for cost-sensitive IoT nodes. The 192 kB RAM size is suitable for applications not requiring extensive local data buffering. Compare against variants with higher RAM or different package sizes if system complexity increases. Consider the 78 MHz CPU speed for processing overhead relative to radio duty cycles.

Part Context

This component belongs to the EFR32MG24 family, which represents Silicon Labs' latest generation of wireless SoCs. The family emphasizes energy efficiency and security for Matter, Thread, and Zigbee implementations. The MG24 series offers scalable memory options and various package sizes to fit diverse form factors while maintaining compatibility with the Simplicity Studio development ecosystem.

Replacement Considerations

Direct substitutes within the same family include EFR32MG24A010F1536IM48 (non-suffix) for identical electrical specs without the tray packaging designation. For pin-compatible alternatives with different memory configurations, evaluate EFR32MG24A021F1024IM40-B for lower RAM/Flash or EFR32MG24B310F1536IM48-B for enhanced security features.
