• Manufacturer Part Number: SLE4436C
• Description: Security & Chip Card ICs
• Manufacturer: Infineon Technologies AG

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.
The secret algorithm offers a challenge & response procedure for individual card
authentication; the optional activation of cipher block chaining allows the certification of a
counter decreasing procedure.
Ensures a minimum and a maximum frequency and proper logical voltage levels.
