8.5.5 Initial memory configuration
The memory configuration of NTAG203 in delivery state is shown in Table 7 “Initial
memory organization”:
The memory configuration in pages 3 to 5 ensures that NTAG203 is a NFC forum Type 2
Tag in INITIALIZED state according to the NFC Forum Technical Specification, Ref. 10
“Tag 2 Type Operation, Technical Specification”. It is recommended that any further
modification of the memory pages 2 to 40 should be according to the Ref. 10 “
Tag 2 Type
