7.2.1 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 numbering of the 64 bits is done according to ISO/IEC 15693-3 starting with the

LSB

1 and ending with the MSB 64. This is in contrast to the general used bit numbering

within a byte (starting with LSB

0).

The TAG type is a part of the UID (bit 41 to 48, after the manufacturer code which is “04h”

for NXP Semiconductors).

The TAG type of the SL2 ICS53/SL2 ICS54 is “02h”
