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 organized as 15 blocks of 8 bits, of
which 7 blocks are accessible as write-once read-many (WORM) memory.
Figure 1.
The LRI64 is accessed using a 13.56 MHz carrier wave. Incoming data are demodulated
from the received amplitude shift keying (ASK) signal, 10% modulated. The data are
transferred from the reader to the LRI64 at 26 Kbit/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
Manchester coding with a single subcarrier frequency of 423 kHz. The data are transferred
from the LRI64 to the reader at 26 Kbit/s, in the high data rate mode.
The LRI64 supports the high data rate communication protocols of ISO 15693 and ISO
18000-3 Mode 1 recommendations. All other data rates and modulations are not supported
by the LRI64.
