• ST23YR (8/16bit) MCU Core4, 8 or 18 Kbytes of EEPROMInnovatron contactless protocol3V and 5V supply voltage rangesInternal CPU clock frequency up to 29 MHzAnti-collision and 16-bit CRC featuresISO/IEC 14443B (Parts 1 to 4) at 106, 212 and 424 kbpsComplies with ISO/IEC 7816-3 T=0Dual or contactless-only configurationDES, DESX and TDES capabilityFull transaction duration, including typical terminal processing compliant with public transportation requirementsCommon Criteria EAL5+EMVCo™ certification
• High security featuresSecurity managed with various access modes: Pin, Session, Always, and Never.A cryptographic certificate controls the access to file modifications. The certificate is computed by the reader (using its built-in SAM) and the card during the transaction, using DES, DESX or TDES encryption.Calypso automatic recovery mechanism: all data modified in the card during a secure session are either completely done or not done at all.Powerful multi-application synchronization capabilityA special mechanism synchronizes modifications between the different applications managed by the card. Each command within the session uses its own secrets or delegates its security to the session security manager.
• Memory organizationMulti-application cardData organized in Files according to ISO/IEC 7816-4Tele-ticketing compliant with the EN 1545 standard data modelThe file structure may be chosen among many options (for example, 2 Calypso applications, 1 multi-purpose application with 9 contracts and an eTicket application)Complete CDLight and CD97 (BX) emulation possibleData is protected by diversified keys (up to 6 keys per directory)
