Procurement Notes
Verify the specific suffix 'C0R' against the manufacturer's latest datasheet to confirm pinout and packaging details. Note that this component may be designated as Not Recommended for New Designs (NRND); consult official documentation for lifecycle status before finalizing procurement plans.
Selection Notes
Select this model when a balance of moderate memory capacity and robust RF performance is required for 2.4 GHz applications. Ensure the design accommodates the 32-VFQFN exposed pad thermal requirements and operates within the specified 1.85 V to 3.8 V supply range.
Part Context
This part belongs to the EFR32MG1B Mighty Gecko family, designed for low-power wireless IoT applications. It shares the same core architecture as other MG1B variants but differs in memory size and specific configuration options defined by the ordering code.
Replacement Considerations
Direct substitutes within the same family include EFR32MG1B232F256GM32-C0R or EFR32MG1B632F512GM32-C0R, provided memory and pin compatibility align with the system requirements.
