EFR32MG1P232F256IM48-C0R

Overview

The EFR32MG1P232F256IM48-C0R is a Mighty Gecko System on Chip (SoC) from Silicon Labs, designed for 2.4 GHz wireless applications. It integrates an ARM Cortex-M4 core operating at up to 40 MHz with 256 kB of flash memory and 32 kB of RAM. The device supports Bluetooth Low Energy and Zigbee protocols, offering a maximum output power of 19.5 dBm and a receive sensitivity of -94 dBm. It operates within a voltage range of 1.8 V to 3.8 V, featuring low current consumption of 8.7 mA during reception and 8.2 mA during transmission. The component is housed in a QFN-48 package.

Feature Summary

• Integrates ARM Cortex-M4 processor with substantial non-volatile memory for complex mesh networking tasks
• Supports multi-protocol wireless standards including Bluetooth Low Energy and Zigbee for versatile connectivity
• Delivers high RF performance with significant output power and sensitive receiver capabilities

Applications

• Smart home automation devices requiring mesh networking
• Wireless sensor nodes for industrial monitoring
• Bluetooth-enabled consumer electronics

Procurement Notes

Verify the specific suffix C0R against official Silicon Labs documentation to confirm package type and temperature grade. Confirm end-of-life status as some sources indicate NRND classification. Ensure compatibility with existing PCB footprints for the QFN-48 package. Validate firmware support for required protocol stacks before procurement.

Selection Notes

Select this component when a balance of moderate memory capacity and high RF power is required for 2.4 GHz applications. It is suitable for designs needing integrated BLE and Zigbee support without external transceivers. Consider the QFN-48 form factor for space-constrained layouts. Evaluate thermal management requirements due to the exposed pad design.

Part Context

This part belongs to the Mighty Gecko family, targeting cost-sensitive yet performance-oriented IoT applications. It sits between lower-memory variants and higher-performance series like the Blue Gecko or Wireless Gecko. The MG1 series represents an established generation of multi-protocol SoCs widely used in mature smart home and industrial products.

Replacement Considerations

Check for EFR32MG12 series variants which offer increased memory and updated features while maintaining pin compatibility. Verify if newer generations like EFR32MG2x provide necessary upgrades in security or power efficiency.
