4.5.1.
ISO 15693-3 read/write commands
The size of the blocks depend on the chip. Known sizes are
1 byte for ST Micro Electronics LRI64 (PIX.NN =
h
0021),
4 bytes for NXP ICODE-SLI (PIX.NN =
h
0014) and Texas Instrument TagIT chips (PIX.NN =
h
0012) and other ST Micro Electronics chips,
8 bytes for EM Marin chips (PIX.NN =
h
FFD1).
Please read the documentation of the VICC you’re working with to know the actual size of its
blocks, and the number of existing blocks.
blocks, and the number of existing blocks.
Some VICCs feature special blocks called either OTP (one-time-programming), WORM (write one,
read many) that can't be overwritten nor erased after a first write operation. Do not write on
those blocks without a good understanding of the consequences.

a.
READ BINARY instruction
In the READ BINARY command APDU,
P1 must be
h
00,
P2 is the address of the first block to be read; please read documentation of your VICC to
know its number of blocks,
Le must be a multiple of the size of the blocks,
When Le=
When Le=
h
00, a single block is returned (length depending on the VICC).
Note: ISO 15693 defines 2 functions to read date: READ SINGLE BLOCK and READ MULTIPLE
BLOCKS. The coupler's READ BINARY instruction tries both of them until one succeed.

b.
UPDATE BINARY instruction
In the UPDATE BINARY command APDU,
P1 must be
h
00,
P2 is the address of the block to be written, please read documentation of your VICC to
know its number of blocks,
Lc must be the size of the block, exactly.
Note: ISO 15693 defines 2 functions to read date: WRITE SINGLE BLOCK and WRITE MULTIPLE
BLOCKS. The coupler's UPDATE BINARY instruction tries both of them until one succeed.
