Description
The LRIS2K is a contactless memory powered by the received carrier electromagnetic
wave. It is a 2048-bit electrically erasable programmable memory (EEPROM). The memory
is organized as 64 blocks of 32 bits. The LRIS2K 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 LRIS2K load variation using Manchester coding with
one or two subcarrier frequencies at 423 KHz and 484 kHz. Data are transferred from the
LRIS2K at 6.6 Kbit/s in low data rate mode and 26 Kbit/s high data rate mode. The LRIS2K
supports the 53 Kbit/s in high data rate mode in one subcarrier frequency at 423 kHz.
The LRIS2K follows the ISO 15693 recommendation for radio frequency power and signal
interface.
