Features
Description
The CryptoRF
resulting in a contactless smart card with advanced security and cryptographic fea-
tures. This device is optimized as a contactless secure memory, for RF smart cards,
and secure data storage, without the requirement of an internal microprocessor.
For communications, the RF interface utilizes the ISO/IEC 14443-2 and -3 Type B bit
timing and signal modulation schemes, and the ISO/IEC 14443-3 Slot-MARKER Anti-
collision Protocol. Data is exchanged half duplex at a 106-kbit/s rate, with a two-byte
CRC_B providing error detection capability. The maximum communication range
between the reader antenna and contactless card is approximately 10 cm when used
with an RFID reader that transmits the maximum ISO/IEC 14443-2 RF power level.
The RF interface powers the other circuits; no battery is required. Full compliance with
the ISO/IEC 14443-2 and -3 standards results in anticollision interoperability with the
AT88RF020 2-Kbit RFID EEPROM product and provides both a proven RF communi-
cation interface and a robust anticollision protocol.
The AT88SC0404CRF contains 4 Kbits of user memory and 2 Kbits of configuration
memory. The 2 Kbits of configuration memory contain four sets of read/write pass-
words, four crypto key sets, security access registers for each user zone, and
password/key registers for each zone.
The CryptoRF command set is optimized for a multicard RF communications environ-
ment. A programmable AFI register allows this IC to be used in numerous applications
in the same geographic area with seamless discrimination of cards assigned to a par-
ticular application during the anticollision process.

... User Memory Configuration Memory Security Fuses AT88SC0404CRF 4 The EEPROM user memory is divided into four user zones as shown in the memory map in Table 1. Multiple zones allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been met ...

... Communication Security Security Methodology Memory Access 5023CS–CRRF–12/06 Communication between the PICC and reader operates in three basic modes. Standard mode is the default mode for the device after power-up and anticollision. Authentication mode is activated by a successful authentication sequence. Encryption mode is activated by a successful encryption activation, following a successful authentication. ...

This function is optional: the host may choose to activate the antitearing function depending on application requirements. When antitearing is active, write commands take longer to execute since more write cycles are required to complete them ...
