Overview
The EFR32MG24A010F1536IM48-B is a Mighty Gecko RF System on Chip featuring an ARM Cortex-M33 core operating at 78 MHz. It integrates a 2.4 GHz radio with +10 dBm output power and -94.4 dBm sensitivity. The device includes 1536 kB of Flash memory and 192 kB of RAM. It supports Bluetooth, Zigbee, and Thread protocols with a maximum data rate of 2 Mbps. Operating voltage ranges from 1.71 V to 3.8 V across a temperature range of -40°C to +125°C in a QFN-48 package.
Feature Summary
- Multiprotocol wireless connectivity supporting Bluetooth, Zigbee, and Thread standards
- High-performance ARM Cortex-M33 processor with Secure Vault security features
- Integrated 2.4 GHz transceiver with optimized current consumption for low-power operation
Applications
- Smart home automation devices
- IoT lighting systems
- Medical device connectivity
- Mesh network endpoints
Procurement Notes
Verify the specific suffix 'B' indicates the reel packaging configuration as documented by Silicon Labs. Confirm that the A010 variant corresponds to the +10 dBm power class and 192 kB RAM specification rather than higher capacity options. Ensure compatibility with the QFN-48 footprint during PCB layout validation.
Selection Notes
Select this component when multiprotocol support for Bluetooth, Zigbee, and Thread is required within a single chip architecture. The +10 dBm output power suits applications where moderate range is sufficient without excessive power drain. The 192 kB RAM limit defines the maximum complexity of concurrent protocol stacks and application logic compared to larger variants.
Part Context
This part belongs to the EFR32MG24 Mighty Gecko family, designed for secure, low-power IoT applications. It shares the same core architecture and pinout with other MG24 variants but differs in memory size, flash capacity, and RF power output levels. The series emphasizes PSA-certified security and energy efficiency for battery-operated devices.
Replacement Considerations
Direct substitutes include EFR32MG24A020F1536IM48-BR for increased RAM or EFR32MG24B210F1536IM48-BR for different security levels. Verify pin-to-pin compatibility and software stack support before swapping between variants with differing memory or power specifications.
