Procurement Notes

Verify the specific suffix 'B' indicates the Secure Vault High security level configuration as documented. Confirm the 128 kB RAM variant matches the design requirements, as other variants may offer different memory sizes. Ensure the QFN-48 package dimensions align with the PCB footprint specifications provided in the official datasheet.

Selection Notes

Select this model when high-level security via Secure Vault is required alongside multi-protocol support. The 128 kB RAM configuration is suitable for applications where memory optimization is prioritized over larger data buffers. Consider the +10 dBm output power against range requirements compared to higher-power variants in the same family.
