7.5 Memory organization
The 168 bytes of the total EEPROM memory are organized in 42 pages each 4 bytes.
144 bytes (36 pages) are available for the user defined data. Each page contains 4 bytes
(32 bits).

7.5.1 UID/serial number
The unique 7 byte serial number (UID) and its two Block Check Character Bytes (BCC)
are programmed into the first 9 bytes of the memory. It therefore covers page 00h, page
01h and the first byte of page 02h. The second byte of page 02h is reserved for internal
data. Due to security and system requirements these bytes are write-protected after the
programming during the IC production.

According to ISO/IEC 14443-3 BCC0 is defined as CT SN0 SN1 SN2.
Abbreviations CT stays for Cascade Tag byte (88h) and BCC1 is defined as SN3 SN4
SN5 SN6.
SN0 holds the Manufacturer ID for NXP (04h) according to ISO/IEC 14443-3 and
ISO/IEC 7816-6 AMD.1.
