Description

The CryptoRF^®family integrates a 13.56 MHz RF interface into a CryptoMemory^®,

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 AT88SC0204CRF contains 2 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.
