  • The CD21-Rev3 is a cost-effective, dual-interface (contact and contactless) secure microcontroller specifically designed for public transport applications, providing a high level of security, high speed transactions and easy capabilities of evolution for transport and multi-service applications.

    The CD21-Rev3 is a Calypso Network Association product. The CD21-Rev3 is available with 4, 8 or 18 Kbytes of EEPROM.

    Key Features

    • Standards
      • Calypso compliant with:
        • Portable Object Application Revision 3 specification
        • Card Application Revision 2 specification
        • Calypso revision 1 contactless protocol
        • CD97 specifications
        • CD97-BX specifications
        • CDLight specifications
        • Automatic fare collection
        • Public transportation access
        • Access control
        • Ticketing payment
        • City services and Events
        • Leisure parks and stadium
        • Corporate card, Student card
        • Single or multiple ticketing applications
        • Transportation payment
        • Stored value (token purse)
        • Loyalty
        • 4, 8 or 18 Kbytes of EEPROM
        • Innovatron contactless protocol
        • 3V and 5V supply voltage ranges
        • Internal CPU clock frequency up to 29 MHz
        • Anti-collision and 16-bit CRC features
        • ISO/IEC 14443B (Parts 1 to 4) at 106, 212 and 424 kbps
        • Complies with ISO/IEC 7816-3 T=0
        • Dual or contactless-only configuration
        • DES, DESX and TDES capability
        • Full transaction duration, including typical terminal processing compliant with public transportation requirements
        • Common Criteria EAL5+
        • EMVCo™ certification
        • Security 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 capability
        • A 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.
        • Multi-application card
        • Data organized in Files according to ISO/IEC 7816-4
        • Tele-ticketing compliant with the EN 1545 standard data model
        • The 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 possible
        • Data is protected by diversified keys (up to 6 keys per directory)
    • Applications
    • Multi-purpose card
    • ST23YR (8/16bit) MCU Core
    • High security features
    • Memory organization
