RF Transceiver ICS Procurement Notes

Verify the specific suffix 'BR' indicates the reel packaging configuration as documented in official distributor listings. Confirm that the component status is active for new designs, noting that some FG23 variants may carry NRND status. Ensure compatibility with required humidity sensitivity handling procedures before assembly.

RF Transceiver ICS Selection Notes

Select this model when a balance of moderate output power (+14 dBm) and large program memory (512 kB) is required. It is suitable for complex firmware applications needing secure Sub-GHz communication without the higher current draw associated with +20 dBm variants. Consider the QFN-48 footprint for PCB layout constraints.

RF Transceiver ICS Part Context

This part belongs to the EFR32FG23 family of Sub-GHz wireless SoCs designed for IoT applications. It shares the same core architecture and radio capabilities as other FG23 models but differs in memory size, output power, and package type. The A010 variant specifically denotes the 512 kB flash and 64 kB RAM configuration.
