SUMMARY DESCRIPTION
The LRI64 is a contactless memory, powered by
an externally transmitted radio wave. It contains a
120-bit non-volatile memory. The memory is orga-
nized as 15 blocks of 8 bits, of which 7 blocks are
accessible as Write-Once Read-Many (WORM)
memory.
Figure 2. Logic Diagram
The LRI64 is accessed using a 13.56MHz carrier
wave. Incoming data are demodulated from the re-
ceived Amplitude Shift Keying (ASK) signal, 10%
modulated. The data are transferred from the
reader to the LRI64 at 26Kbit/s, using the “1-out-
of-4” pulse encoding mode.
Outgoing data are sent by the LRI64, generated by
load variation on the carrier wave, using Manches-
ter coding with a single sub-carrier frequency of
423kHz. The data are transferred from the LRI64
to the reader at 26Kbit/s, in the high data rate
mode.
The LRI64 supports the high data rate communi-
cation protocols of the ISO15693 recommenda-
tion. All other data rates and modulations are not
supported by the LRI64.

Memory Mapping
The LRI64 is organized as 15 blocks of 8 bits as
shown in
Figure 3.
Each block is automatically
write-protected after the first valid write access.
Figure 3. LRI64 Memory Mapping
The LRI64 uses the first 8 blocks (blocks 0 to 7) to
store the 64-bit Unique Identifier (UID). The UID is
used during the anti-collision sequence (Invento-
ry). It is written, by ST, at time of manufacture, but
part of it can be customer-accessible and custom-
er-writable, on special request.
The LRI64 has an AFI register, in which to store
the Application Family Identifier value, which is
also used during the anti-collision sequence.
The LRI64 has a DSFID register, in which to store
the Data Storage Format Identifier value, which is
used for the LRI64 Inventory answer.
The five following blocks (blocks 10 to 14) are
Write-Once Read-Many (WORM) memory. It is
possible to write to each of them once. After the
first valid write access, the block is automatically
locked, and only read commands are possible.
