1.1 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.
