SLE 4436/36E is designed for applications in prepaid telephone cards. The chip consists of an
EEPROM memory of 221 bit, a ROM of 16 bits, a control/security unit and a special computing unit
for chip authentication. The shaded blocks in the block diagram (Figure 3) contain the enhanced
features of SLE 4436/36E compared to SLE 4406/06E.

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.
$XWKHQWLFDWLRQꢀ8QLW
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.
