Description
The LRIS2K is a contactless memory powered by the received carrier electromagnetic wave, which follows the ISO 15693 recommendation for radio frequency power and signal interface. 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.
