NTAG213F/216F
NXP Semiconductors
NFC Forum T2T IC with 144/888 bytes user memory and field detection
8.5.4 Capability Container (CC bytes)
The Capability Container CC (page 3) is programmed during the IC production according
to the NFC Forum Type 2 Tag specification (see Ref. 2). These bytes may be bit-wise
modified by a WRITE or COMPATIBILITY_WRITE command. See example for
NTAG213F in Figure 12.

Fig 12. CC bytes
The parameter bytes of the WRITE command and the current contents of the CC bytes
are bit-wise OR’ed. The result is the new CC byte contents. This process is irreversible
and once a bit is set to logic 1, it cannot be changed back to logic 0.
Any write operation to the CC bytes is tearing-proof.
The default values of the CC bytes at delivery are defined in Section 8.5.6.
To maintain compatibility to NFC Forum Type 2 tag specification (and interoperability with
different NFC device), it is recommended to not change the default capability container
content.
8.5.5 Data pages
Pages 04h to 27h for NTAG213F and 04h to E1h for NTAG216F are the user memory
read/write area.
The access to a part of the user memory area can be restricted using a password
verification. See Section 8.9 for further details.
The default values of the data pages at delivery are defined in Section 8.5.6.
