Philips I•Code Transponders

Philips I•Code transponders are high frequency (13.56MHz) RFID devices.

Each transponder has 512 bits of memory. Data is segmented into 4 byte

(32 bit) blocks that are uniquely addressable for a total of 16 blocks. Each

memory block is lockable using the write protect function during the

writing process. The first two blocks of data (block 0 and 1) are

pre-programmed, non-changeable, and 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 these transponders for your own use, and don’t require

universal special function or family codes, then you can program blocks 3

through 15.

* The bits in block 2 determine the write access conditions for itself and

each of the remaining blocks. You can leave blocks 2 through 15 open or

you can write-protect them. Write-protected blocks (included block 2) can

never be written to from the moment they are locked
