Eurochip 77
• Programming Unit
The programming voltage for the EEPROM/PROM is generated internally.
• Backup Unit
An associated backup bit indicates an interrupt caused by e.g. tearing a card out of a reader
without mechanical locking device during a reloading cycle of a devaluated counter stage.
Note: The counter tearing protection may be disabled by mask option
• Authentication Unit
The secret algorithm offers a challenge & response procedure for individual card authentication
fully compatible with Eurochip Family.
The optional activation of cipher block chaining allows the certification of a counter decreasing
procedure and is fully compatible with Eurochip Family.
• Card-Trash mechanism
Physical blocking of chip functions such as authentication and generation of programming
voltage.
• Security Interface
Ensures a minimum and a maximum frequency and proper logical voltage levels.
3 Migration
Member of Infineon’s Telecom ICs family.
IMEM technology offers sophisticated security features compared to NMOS technology. Due to
different electrical characteristics (e.g. power consumption) an acceptance test in the terminals is
recommended.
Identification and Counter fully functional compatible with existing members of Eurochip Family and
SLE 4406S/06SE products for easy upgrade to higher security levels.
Use of authentication is optional and controlled by the terminal. This allows smooth upgrade of the
terminals with a Security Module (SAM).
