SUMMARY DESCRIPTION
The LRI512 is a contactless memory, powered by
an externally transmitted radio wave. It is fully
compliant with the ISO15693 recommendation for
radio-frequency power and signal interface.
The LRI512 contains 512 bits of Electrically
Erasable Programmable Memory (EEPROM). The
memory is organized as 16 blocks of 32 bits.
Figure 2. Logic Diagram
The LRI512 is accessed by modulating the
13.56 MHz carrier frequency. Incoming data are
demodulated from the received signal amplitude
modulation (ASK, Amplitude Shift Keying). The
received ASK wave is 10% or 100% modulated
(amplitude modulation). The Data transfer rate is
1.6 kbit/s using the 1/256 pulse coding mode and
26 kbit/s using the 1/4 pulse coding modes.
Outgoing data are generated by antenna load
variation, using the Manchester coding, using one
or two sub-carrier frequencies at 423 kHz and
484 kHz. The Data transfer rate is 6.6 kbit/s, in the
low data rate mode, and 26 kbit/s, in the fast data
rate mode.

Memory Mapping
The LRI512 is divided in 16 blocks of 32 bits. Each
block can be individually Write Protected using a
specific Lock command.
Table 2. LRI512 Memory Map
The User Area consists of blocks that are always
accessible in READ. WRITE commands are pos-
sible if the addressed block is not locked. During a
WRITE, the 32 bits of the block are replaced by the
new 32-bit value.
The LRI512 also has a 64-bit block that is used to
store the 64-bit Unique Identifier (UID). This UID is
compliant to the ISO15963 description, and its val-
ue is used during the anti-collision sequence (IN-
VENTORY). This block is not accessible by the
user, and the value is written by ST on the produc-
tion line.
The LRI512 also has an AFI register in which the
Application Family Identifier is stored, for use in
the anti-collision algorithm.
