EFR32MG24B010F1536IM40-B

Overview

The EFR32MG24B010F1536IM40-B is a wireless System on Chip (SoC) from the Silicon Labs EFR32MG24 family, designed for Bluetooth and Zigbee applications. It features an ARM Cortex-M33 core operating at a maximum clock frequency of 78 MHz. The device integrates 1536 kB of Flash memory and 256 kB of RAM. It operates within a supply voltage range of 1.71 V to 3.8 V and supports a data rate of up to 2 Mbps at 2.4 GHz. Key electrical specifications include a transmit output power of +10 dBm, a receive sensitivity of -94.4 dBm, a receive current of 4.4 mA, and a transmit current of 19.1 mA. The component is housed in a QFN-40 package and is rated for an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates Secure Vault High security hardware for robust data protection
• Supports both Bluetooth and Zigbee wireless protocols
• Features high-output RF capability with +10 dBm transmit power
• Includes ARM Cortex-M33 processor with extensive memory resources

Applications

• Smart home devices requiring secure connectivity
• Industrial sensor networks operating in extreme temperatures
• Commercial building automation systems
• Medical IoT devices needing reliable low-power communication

Procurement Notes

Verify the specific suffix 'B' indicates the Secure Vault High configuration and '+125C' industrial temperature rating as documented. Confirm the QFN-40 package type matches your PCB footprint requirements. Ensure compatibility with the 1.71V to 3.8V supply voltage range for your target application design. Cross-reference the datasheet for exact pinout definitions and recommended external components.

Selection Notes

Select this model when high security (Secure Vault High) and extended temperature operation (+125C) are mandatory. Choose this variant over lower-memory options if 1536 kB Flash and 256 kB RAM are required for complex firmware. Opt for the +10 dBm output power version if long-range coverage is needed without excessive power consumption. Consider the QFN-40 package constraints during layout planning.

Part Context

This component belongs to the EFR32MG24 series, which represents Silicon Labs' latest generation of wireless SoCs. The MG24 family is engineered for high performance and energy efficiency in sub-GHz and 2.4 GHz markets. This specific part number denotes the B-series variant with enhanced security features and industrial-grade thermal stability, distinguishing it from standard commercial grade counterparts.

Replacement Considerations

Direct substitutes within the same family include EFR32MG24A020F1024IM40-B or EFR32MG24B020F1536IM48-B, though pinouts and memory configurations differ. Verify that any replacement maintains the required Secure Vault High level and +125C temperature rating. Package changes from QFN-40 may require PCB redesign.
