I·Code Tags
I • Code labels are also high frequency (13.56MHz) devices but have 512
bits of storage capacity. Data is addressed in sixteen blocks of 32 bits, each
block containing four bytes. The first two blocks of data (block 0 and 1) are
used for storage of a unique 64 bit serial number. The next two blocks
(blocks 2 and 3) are used for storage of configuration information; block 4
is used for family or application identification and blocks 5 to 15 are free
for user application use.
If you are using I
• Code tags for your own use, and don’t require universal
special function or family codes, then you can program blocks 3 through 15.
