EFR32MG24A010F1536IM40-BR

Overview

The EFR32MG24A010F1536IM40-BR is a Bluetooth System-on-Chip from the Silicon Labs MG24 family, designed for 2.4 GHz wireless applications. It features an ARM Cortex-M33 core operating at a maximum clock frequency of 78 MHz with a 32-bit data bus width. The device integrates 1536 kB of Flash program memory and 192 kB of RAM. It supports a maximum data rate of 2 Mbps with a transmit output power of +10 dBm and a receive sensitivity of -94.4 dBm. The unit operates on a single supply voltage ranging from 1.71 V to 3.8 V and functions within a temperature range of -40°C to +125°C. It is housed in a QFN-40 package.

Feature Summary

• Integrates an ARM Cortex-M33 processor with DSP instructions and a floating-point unit for efficient signal processing.
• Supports multiple wireless protocols including Bluetooth Low Energy, Zigbee, Matter, and Thread.
• Includes hardware acceleration capabilities such as a matrix-vector processor for AI/ML tasks.
• Enables direction finding functionality using Angle of Arrival (AoA) and Angle of Departure (AoD).

Applications

• Smart home devices requiring multi-protocol connectivity
• Industrial IoT sensors and controllers
• Bluetooth mesh networking nodes
• Thread and Matter enabled smart accessories

Procurement Notes

Verify the specific suffix 'BR' indicates reel packaging when sourcing components. Confirm that the ordering part number matches the exact memory configuration of 1536 kB Flash and 192 kB RAM. Ensure the thermal grade corresponds to the +125°C operational requirement. Cross-reference the datasheet revision to confirm pinout compatibility for QFN-40 implementations.

Selection Notes

Select this component for designs requiring high memory capacity within a compact QFN-40 footprint. The +10 dBm output power is suitable for standard range indoor applications. Consider the 192 kB RAM limit for complex protocol stacks or large data buffers. Verify that the system design can accommodate the required 40 MHz crystal oscillator for RF operation.

Part Context

This model belongs to the EFR32MG24 series, which targets high-performance, low-power wireless applications. It shares the same core architecture and radio specifications as other variants in the MG24 family but differs in memory size and package type. The A010 designation typically denotes the +10 dBm power class within this product line.
