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.
