EM Microelectronic announces 13.56 MHz transponder IC with crypto for high security and 13.56MHz multi-standard reader IC... The new family of high frequency RFID ICs completes EM's UHF and 125kHz broad portfolio of products in order to serve the widest possible range of RFID applications.

EM Microelectronic is a semi- conductor manufacturer specialized in the design and production of ultra low power, low voltage integrated circuits for battery-operated and field-powered applications in consumer, automotive and industrial areas. EM Microelectronic has over 26 years of experience in the design of ICs processing analog and digital signals simultaneously. The product portfolio encompasses RFID circuits, smart cards, ultra-low power microcontrollers, power management, LCD drivers and displays, sensor and opto-electronic ICs, mixed-mode arrays and standard analog ICs. EM Microelectronic also offers module and bumping services and manufactures not only standard circuits and ASICs, but also system solutions and modules for applications such as access control, radio frequency identification, mobile phones, mass-market consumer appliances, alarm and security systems, utility and heating meters, sensor signal processing, controlling, car immobilization, electronic automotive subsystems and many more.

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. The resonant capacitor value is selected by metal mask.
