each block consists of 4 bytes (1 block = 32 bits). Bit 0 in each byte represents the least

significant bit (lsb) and bit 7 the most significant bit (msb), respectively.

User EEPROM map looks totally the same from NFC and I2C perspective.

The last block contains the 16-bit counter (see Section 8.1.2.1). It is only accessible from

NFC perspective.

NTAG 5 link offers 2048 bytes (16384 bits) of user memory.

Counter

User data at delivery contains an NFC Forum-compliant capability container and an

NDEF message containing the URL www.nxp.com/nfc. First 6 blocks are initialized as

illustrated in below table. The counter block is initialized with all 00h. Content of the rest

of the user memory is undefined and contains random (rnd) data at delivery.

8.1.2.1 16-bit counter

Last Block of the user memory contains the 16-bit counter. The block can be accessed

with the standard read and write commands but special data format is required.

The standard protection conditions for the user memory are not valid for the counter

block.

Counter block can only be accessed from NFC perspective.

The 16-bit counter can be

• preset to initial start value protected with the write password or by mutual

authentication with a key with the Write privilege
