CD21-rev3

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)
