EFR32MG24A010F1536IM48-BR

Overview

The EFR32MG24A010F1536IM48-BR is a Bluetooth System on Chip from the Mighty Gecko family, manufactured by Silicon Labs. It integrates an ARM Cortex-M33 core operating at a maximum clock frequency of 78 MHz with 32-bit data bus width. The device features 1536 kB of Flash program memory and 192 kB of RAM. It includes a 2.4 GHz radio supporting a maximum data rate of 2 Mbps, delivering +10 dBm output power and -94.4 dBm sensitivity. Operating voltage ranges from 1.71 V to 3.8 V. It supports I2C interfaces and functions within a temperature range of -40°C to +125°C. The component is housed in a QFN-48 package.

Feature Summary

• Integrates a 32-bit ARM Cortex-M33 processor for efficient code execution
• Supports 2.4 GHz wireless communication with high transmission power
• Provides substantial onboard memory for complex protocol stacks

Applications

• Smart home devices requiring robust wireless connectivity
• IoT sensors utilizing low-power Bluetooth protocols
• Industrial control systems needing wide temperature operation

Procurement Notes

Verify the specific suffix BR indicates reel packaging when sourcing components. Confirm that the A variant corresponds to the standard security level rather than Secure Vault High configurations found in other MG24 models. Ensure compatibility with QFN-48 footprints during PCB layout validation. Cross-reference datasheet revisions to confirm pinout consistency for existing designs.

Selection Notes

Select this model when 192 kB RAM is sufficient for application requirements compared to higher memory variants. Consider the QFN-48 package size constraints against available board space. Evaluate thermal management needs given the +125°C operational limit. Compare against B-series parts if enhanced security vaults are not required for the specific use case.

Part Context

This component belongs to the EFR32MG24 series, designed for multiprotocol wireless applications. It serves as a key element in Silicon Labs' Mighty Gecko portfolio, targeting cost-sensitive IoT deployments. The part number structure identifies the radio class, memory configuration, and package type distinct from other series members.

Replacement Considerations

EFR32MG24A010F1536IM48-B is a tray-packaged equivalent with identical electrical specifications.
