DATA ELEMENT DEFINITION

1. Unique Identifier (UID)

The MB89R119B has a 64-bit unique identifier (UID). The UID is used to distinguish a transponder from

another transponder in the anti-collision algorithm.

The UID consists of the 3 items shown in the following.



The MSB 8-bit data whose value is always “E0H” (bit 57 to bit 64)



An 8-bit IC manufacturer code whose value is always “08H” according to ISO/IEC 7816-6/AMI (bit 49 to

bit 56)



Unique 48-bit serial number assigned by FUJITSU SEMICONDUCTOR MEMORY SOLUTION (bit 1 to

bit 48)

Among the unique 48-bit serial number assigned by FUJITSU SEMICONDUCTOR MEMORY SOLUTION,

the 1 byte from bit 41 to bit 48 defines MB89R119B code whose value is “02H”. And the 5 bytes from bit 1

to bit 40 define Other serial number.
