EFR32BG12P433F1024GM48-C

RF Transceiver ICS Overview

The EFR32BG12P433F1024GM48-C is a Blue Gecko RF System-on-Chip featuring an ARM Cortex-M4 core operating at 40 MHz. It supports Bluetooth Low Energy and proprietary protocols across sub-GHz (169, 315, 433, 490, 868, 915 MHz) and 2.4 GHz bands. The device includes 1 MB flash, 256 kB RAM, and 31 GPIOs in a QFN-48 package. It delivers up to 19 dBm output power with -91.3 dBm sensitivity. Operating voltage ranges from 1.8 V to 3.8 V, with receive current of 8.4–10 mA and transmit current of 8.5–35.3 mA.

RF Transceiver ICS Feature Summary

• Supports dual-band operation for sub-GHz ISM bands and 2.4 GHz wireless communication
• Integrates high-performance ARM Cortex-M4 processor with substantial memory resources
• Provides configurable radio output power up to 19 dBm for extended range applications

RF Transceiver ICS Applications

• Bluetooth Low Energy mesh networking devices
• Sub-GHz proprietary sensor networks
• Smart home actuators and controllers
• Industrial monitoring nodes

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature grade compliance against project requirements. Confirm the QFN-48 package dimensions match PCB footprint specifications. Ensure the sub-GHz frequency variants align with regional regulatory approvals for target markets. Cross-reference the manufacturer's latest datasheet for any updates on pinout or electrical characteristics prior to final design approval.

RF Transceiver ICS Selection Notes

Select this model when both sub-GHz and 2.4 GHz connectivity are required within a single node. The 256 kB RAM supports complex protocol stacks and data buffering. Compare against BG12 variants with lower memory if cost reduction is prioritized over application complexity. Ensure the 19 dBm output power meets link budget requirements for the intended deployment environment.

RF Transceiver ICS Part Context

This component belongs to Silicon Labs' Blue Gecko family, optimized for Bluetooth Low Energy and proprietary wireless applications. It shares the MG12/FG12 platform architecture but focuses on BLE capabilities. The P433 designation indicates specific memory and radio configurations distinct from other series members like the P232 or P432 variants.

RF Transceiver ICS Replacement Considerations

EFR32BG12P433F1024IM48-C offers identical specifications with an industrial temperature rating instead of commercial grade.
