EM MICROELECTRONIC - MARIN SA EM4035 13.56MHz CRYPTO ISO15693 Compliant Contactless Identification Device General Description Features The EM4035 is a CMOS integrated circuit intended for use in contactless Read/Write transponders. The EM4035 is completely ISO15693 compliant and is a member of ISO 15693 standard passive Read/Write RF tags operating at 13.56MHz. The Chip contains an implementation of a crypto-algorithm with 96 bit of user configurable secret-Keys contained in EEPROM. The 3.2k bit EEPROM memory contained in the chip is organized in 50 words of 64 bits, each word can be irreversibly locked. The memory contains a unique 64-bit serial number (UID). An ISO 15693 anticollision algorithm allows operating more tags in the field simultaneously. The 64bits UID as defined in ISO15693 standard is factory programmed and locked. It includes a 6 bits chip type and a 10 bits customer code made specific on request.
