Unique identifier (UID)

Members of the LRI64 family are uniquely identified by a 64-bit unique identifier (UID). This

is used for addressing each LRI64 device uniquely and individually, during the anticollision

loop and for one-to-one exchange between a VCD and an LRI64.

The UID complies with ISO/IEC 15963 and ISO/IEC 7816-6. It is a read-only code, and

comprises (as summarized in Figure 13):

●

8-bit prefix, the most significant bits, set at E0h

●

8-bit IC manufacturer code (ISO/IEC 7816-6/AM1), set at 02h (for STMicroelectronics)

●

48-bit unique serial number
