Infineon Technologies AG has announced availability of the SLE 66PE family of new high-security contactless-interface MCUs. Products in the new family are designed to further advance performance and execution speeds for electronic passports, identity cards, e-government cards and payment cards.

For global reader interoperability, every family member fully complies with all major present-day contactless interface formats with their respective data transmission protocols. They are the only contactless chips today that are able to communicate with the existing reader device infrastructure all over the world.

Security levels for identification and payment applications are expected to continue to rise. These high-security contactless chips shorten authentication times by speeding up encryption and decryption operations. Their high transaction speeds of up to 848Kbps for communicating with the reader device is twice the speed of the typical transaction. The integral security concept fulfils all mandatory international security requirements.

Global reader interoperability
The SLE 66PE portfolio supports the complete range of contactless proximity interfaces, such as ISO/IEC 14443 Type B and Type A with optional ISO/IEC 18092 passive mode and optional Mifare emulation. Therefore, cards or tokens integrating SLE 66PE products can communicate with the existing reader infrastructure for contactless and dual-interface applications. This is in contrast to other commercially available contactless chip card ICs that are restricted to a subset of international contactless interface standards or disregard the high-security levels demanded by some applications, such as e-government.

Security levels of identification applications of electronic passports, identity cards and government cards are expected to further increase in 2007 by adding advanced encryption algorithms to be executed during authentication. By using SLE 66PE products, which feature an internal clock rate of 30MHz and provide up to 848Kbps of transaction performance, these higher security levels will not expand authentication times. The new MCUs also feature contactless cryptography for Rivest, Shamir, Adlemen, Data Encryption Standard (DES), Triple-DES and Elliptic Curves, and other security mechanisms including active protective shields on the surface of the chip and sensors that help prevent unauthorized people from reading the contents of the chip.

Six devices within the SLE 66PE family are available now. These devices have various EEPROM size and contactless interface. All six products offer a contact-based interface according to ISO/IEC 7816 for usage in dual-interface applications.

The SLE 66CLX800PE features 80Kbytes of EEPROM, 240Kbytes of ROM and a 7,100-byte RAM including Crypto RAM. With its tailored set of EEPROM/ROM and RAM memory sizes, SLE 66CLX800PE suits the International Civil Aviation Organization (ICAO) requirements for the secure storage of the biometric and personal data in travel documents.
