*HQHUDO'HVFULSWLRQ
SLE 4466 is designed for prepaid payment applications (e.g. vending machines, electronic
metering) and secured payment applications (e.g. loyalty scheme). The chip consists of an
EEPROM memory of 496 bit (incl. 8 bit Manufacturer data), a ROM of 16 bit, a control/security unit,
a memory access control logic, a special computing unit for chip authentication and 3 flag bits for
mode selection.

Setting of the address counter is synchronously with CLK. The chip provides the Answer to
Reset (ATR) for synchronous transmission according to ISO/IEC 7816.

Access to Authentication Unit and Memory Unit is controlled by a secret code (mode
dependent).
$XWKHQWLFDWLRQ8QLW
The secret algorithm offers a challenge & response procedure for card authentication
(individual key) and as signature for data and counter status integrity. Additionally cipher block
chaining of the responses allows the certification of a Value Counter decreasing procedure.
The authentication is controlled and limited by the response counter also avoiding a repetition
of identical responses.

The programming voltage for the EEPROM/PROM is generated and controlled internally.

Ensures a minimum and a maximum frequency and proper logical voltage levels.
