Unique Identifier (UID)

Members of the SRIX4K family are uniquely identified by a 64-bit Unique Identifier (UID).

This is used for addressing each SRIX4K device uniquely after the anticollision loop. The

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

comprises (as summarized in Figure 49):

●

an 8-bit prefix, with the most significant bits set to D0h

●

an 8-bit IC Manufacturer code (ISO/IEC 7816-6/AM1) set to 02h (for

STMicroelectronics)

●

a 6-bit IC code set to 00 0011b = 3d for SRIX4K

●

a 42-bit Unique Serial Number

Power-On state

After Power-On, the SRIX4K is in the following state:

–

It is in the low-power state.

–

It is in READY state.

–

It shows highest impedance with respect to the reader antenna field.

–

It will not respond to any command except INITIATE().
