Engineering Brief

ST25TN512 uses the Type 2 protocol, not ISO 15693 or Type 5. Its delivery Capability Container advertises 64 bytes; configuration can change memory allocation, so use the exact map in DS13433 rather than the family maximum. Augmented NDEF provides dynamic content without rewriting EEPROM.
