LRIS64K
65536-bit ISO15693 contactless memory with 64-bit UID, AFI, DSFID, anti-collision, kill function and password protection-
Active
The LRIS64K is a contactless memory powered by the received carrier electromagnetic wave, which follows the ISO/IEC 15693 and ISO/IEC 18000-3 mode 1 recommendation for radio-frequency power and signal interface. It is a 64 Kbit electrically erasable programmable memory (EEPROM). The memory is organized as 64 sectors divided into 32 blocks of 32 bits.
The LRIS64K 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 LRIS64K load variation using Manchester coding with one or two subcarrier frequencies at 423 kHz and 484 kHz. Data are transferred from the LRIS64K at 6.6 Kbit/s in low data rate mode and 26 Kbit/s in high data rate mode. The LRIS64K supports the 53 Kbit/s data rate in high data rate mode with a single subcarrier frequency of 423 kHz.
The LRIS64K also features a unique 32-bit multi-password protection scheme.
