The SLE 55R04 is the first member of a new generation of memory chips complying to the ISO 14443 Type-A (modulation ASK 100%) for contactless proximity smart cards. This family of contactless chips focus on high security, very flexible memory configuration and reduction of the chip size. The SLE 55R04 is the first chip of the 55family which supplies the user with different memory sizes meeting the requirements of variable applications. The SLE 55R04 does fully comply to the proposed new ISO 14443 Type-A. After a (R) software upgrade Mifare systems can also profit from the features of the 55-family. 6\VWHP GHVFULSWLRQ The system consists of a smart card on the one hand and a card reader together with an antenna on the other hand. The operating distance between card and reader antenna can vary from 0 cm up to 10 cm. The card's antenna consists of a simple coil with a few turns embedded in plastic. The contactless smart cards are passive and work batteryless. The high speed RF communication interface allows to transmit data with 106 Kbit/s. 7KH 8VHU)ULHQGO\ &RQWDFWOHVV 6\VWHP The high data transmission rate permits short transaction times and user-friendly transaction times. For example, a ticketing transaction can be handled in less than 100 ms so that the card user needs not to stop at the reader target (antenna). The card even may remain in the wallet of the user even if there are coins in it. An intelligent anticollision function allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field. 0XOWL$SSOLFDWLRQ )XQFWLRQDOLW\ The SLE 55R04 shows its user-friendliness by its unrivaled memory flexibility. It provides the possibility to use one big sector or 2 or more smaller sectors with different sizes each. Optionally one sector is to be opened without authentication to read e.g. additional card and issuer information. Thus the SLE 55R04 can meet the needs of low memory applications like public transport as well as the more extensive needs of payment systems, which is also supported by the value function Two different key sets for each memory sector support systems using key hierarchies. +LJK 6\VWHP 6HFXULW\ In the system design, special emphasis has been placed on security against fraud. An access to the card memory is only possible after a two pass authentication. Memory operations are restricted by pageconfigurable access conditions. The serial number is unique for each card and can never be changed.

The SLE 55R04 contains on a single chip a 608 byte EEPROM, an analogue interface for contactless energy and data transmission and a control unit. The power supply and data are transferred to the SLE 55R04 via an antenna which consists of a coil with a few turns directly connected to the chip. No further external components are necessary. The circuit is designed according to ISO 14443 to communicate with a card reader at an operating distance between 0 cm and 10 cm.

Analogue Interface, consisting of - Modulator / Demodulator - Rectifier - Clock Separator - Power on Reset - Voltage Regulator Anticollision Internal logic of the SLE 55R04 ensures the recognition of several cards in the field which may be selected and operated simultaneously. This is done by the ELW RULHQWHG DQWLFROOL VLRQ PHWKRG with 4 or 7 byte serial numbers (complying to ISO 14443 - cascading of serial numbers). Authentication Control Access to key-protected sectors is only permitted after authentication with an appropriated key. One sector is optionally configurable without key protection and authentication. Only one sector is to be opened within a session. Control Logic: Each page can only be accessed according to the individual access conditions programmed for every page and every key. EEPROM-Interface
