ICODE DNA

6.2.1 Unique identifier

The 64-bit unique identifier (UID) is programmed during the production process according

to ISO/IEC 15693-3 and cannot be changed afterwards.

The 64 bits are numbered according to ISO/IEC 15693-3 starting with LSB 1 and ending

with MSB 64. This is in contrast to the general used bit numbering within a byte.

The TAG type is a part of the UID (bit 41 to 48, next to the manufacturer code which is

“04h” for NXP Semiconductors).

The TAG type of the ICODE DNA IC is “01h”.

Bit 37 and bit 36 are used to differentiate between ICODE SLI, ICODE SLIX, ICODE

SLIX2 and ICODE DNA (refer to Table 3).

6.2.2 User memory

Access to the user memory is possible with READ and WRITE commands depending on

the settings of the access conditions.

Only Blocks 0 to 63 can be addressed with standard READ and WRITE commands.

Remark: Block 63 contains the 16-bit counter and cannot be used to store user data.

READ and WRITE commands to that block require special data considerations.
