XRA00
MEMORY MAPPING
The XRA00 is divided into 8 blocks of 16 bits. The
device is read bit by bit and written to on a block by
block basis (16 bits at a time). The XRA00 memory
map is shown in
In the XRA00, the first block is used to store the
CRC value as defined in the ePC specification.

Note: 1. ST may write part of the ePC code.
USER mode
After programming the ePC information, the
XRA00 can be locked. Once locked, the XRA00

The next 6 blocks are used to store the 96-bit ePC
code that is used during the inventory sequence.
The last block is divided into two 8-bit areas, one
that contains the Kill Code and the other that con-
tains the Lock Code used to protect the memory
data contents.
