Procurement Notes

Verify component authenticity through authorized distributors as this part is scheduled for obsolescence. Confirm that the QFN-48 package matches your PCB footprint requirements. Ensure supply chain stability due to potential end-of-life status affecting long-term availability. Check RoHS compliance documentation for specific regional regulatory needs before finalizing procurement orders.

Selection Notes

Select this model when dual-band flexibility is required without switching components. Compare against single-band variants if only one frequency is needed to optimize cost. Consider the 256 kB flash size for application complexity. Evaluate the 32 kB RAM limit against stack requirements for BLE or Thread implementations. Assess thermal performance given the QFN-48 package constraints in enclosed designs.

Part Context
