STMicroelectronics RFID products
CR14 and CRX14 is reader chip.
CRX14 has anti clone algorithm, it can be masked customized key as well as SRIX4k for anti-clone application.
SRT512 is for mass transportation application like NXP Ultralight, SRT512 total memory size is 512bit and has 2 count-down binary counter,.
SRI512 is similar with SRT512 , only one different point , SRI512 0-4 block are OTP and 7-15 block are EEPROM, SRT512 all block are EEPROM.
SRI2k is similar with SRI512 , but its memory is 2kbit, also 0-4 block is OTP and 7-63 block are EEPROM.
SRI4k is similar with SRI512, but its memory size is 4k bit, also 0-4 block is OTP and 7-127 block are EEPROM.
LRI2k is compatible with NXP ICODE 2, but LRI2k memory is 2k bit.
LRIS2k is 2kbit memory size, but each block can use 1 of 3 passwords to control read and write.
LRI64 is low end ISO15693 product, only 64bit memory size.
SRI2K, 13.56 MHz short-range contactless memory chip with 2048-bit EEPROM and anticollision functions
