RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized channels due to the NRND status. Confirm that the BGA-125 package aligns with PCB footprint requirements. Ensure design accounts for moisture sensitivity levels during reflow soldering processes. Validate that the 10 dBm transmit power meets specific regulatory and range requirements for the target application environment.

RF Transceiver ICS Selection Notes

This model is designated as Not Recommended for New Designs (NRND). Engineers should evaluate successor series such as the EFR32MG21 or MG24 for long-term availability. Consider if the 10 dBm output power suffices compared to higher-power variants like the P432 series. Assess whether the 256 kB RAM capacity adequately supports complex protocol stacks and application logic.
