CD21-rev3Dual interface / Calypso revision 3.1 with 4,8 or 18KB EEPROM
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.
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
- Multi-purpose card
Single or multiple ticketing applications Transportation payment Stored value (token purse) Loyalty
- ST23YR (8/16bit) MCU Core
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
- High security features
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.
- Memory organization
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)
