User memory organization
The M24LR04E-R is divided into 4 sectors of 32 blocks of 32 bits, as shown in
Figure 6
and/or write-protected using a specific password command. Read and write operations are
possible if the addressed data are not in a protected sector.
The M24LR04E-R also has a 64-bit block that is used to store the 64-bit unique identifier
(UID). The UID is compliant with the ISO 15963 description, and its value is used during the
anticollision sequence (Inventory). This block is not accessible by the user and its value is
written by ST on the production line.
The M24LR04E-R includes an AFI register that stores the application family identifier, and a
DSFID register that stores the data storage family identifier used in the anticollision
algorithm.
The M24LR04E-R has four 32-bit blocks that store an I
codes.
