Block Diagram
Memory Unit Manufacturer Code (16-Bit Code) and Manufacturer Data (3rd Byte) for unique coding of an application. For SLE 7736E its recommended to use the 3rd byte for administration purpose to uniquely identify the application by the 16-bit manufacturer code and the 3rd byte; -- Identification Data (e.g. serial number, expiry date); -- Counter; -- Data Areas.

* * 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.

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).
