Procurement Notes

Verify the specific suffix 'B' indicates the correct temperature grade and packaging configuration as defined by Silicon Labs. Confirm that the QFN-48 package dimensions match the target PCB footprint requirements. Ensure the design accounts for the 1.71 V minimum supply voltage and thermal dissipation characteristics associated with the exposed pad layout during operation.

Selection Notes

Select this model when a balance of moderate memory capacity and high RF performance is required for 2.4 GHz protocols. It is appropriate for designs needing 1024 kB Flash without the higher storage options available in other variants. Consider the QFN-48 form factor for space-constrained applications requiring multiple GPIOs and standard interface peripherals.
