Description

The LRI1K is a contactless memory powered by the received carrier electromagnetic wave.

It is a 1024-bit electrically erasable programmable memory (EEPROM). The memory is

organized as 32 blocks of 32 bits. The LRI1K is accessed via the 13.56 MHz carrier

electromagnetic wave on which incoming data are demodulated from the received signal

amplitude modulation (ASK: amplitude shift keying). The received ASK wave is 10% or

100% modulated with a data rate of 1.6 Kbit/s using the 1/256 pulse coding mode or a data

rate of 26 Kbit/s using the 1/4 pulse coding mode.

Outgoing data are generated by the LRI1K load variation using Manchester coding with one

or two subcarrier frequencies at 423 kHz and 484 kHz. Data are transferred from the LRI1K

at 6.6 Kbit/s in low data rate mode and 26 Kbit/s fast data rate mode. The LRI1K supports

53 Kbit/s in high data rate mode with one subcarrier frequency at 423 kHz.

The LRI1K follows the ISO 15693 recommendation for radio-frequency power and signal

interface.
