Description The Atmel CryptoRF family integrates a 13.56MHz RF interface into an Atmel CryptoMemory . This product line is ideal for RF tags and contactless smart cards that can benefit from advanced security and cryptographic features. This device is optimized as a contactless secure memory for 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 Anticollision Protocol. Data is exchanged half duplex at a 106-kbit per second rate, with a two-byte CRC B providing error detection capability. The RF interface powers the other circuits no battery is required. Full compliance with the ISO/IEC 14443-2 and -3 standards and provides both a proven RF communication interface and a robust anticollision protocol. AT88RF04C contains four kilobits of user memory and two kilobits of configuration memory. The two kilobits of configuration memory contain: Four sets of read/write passwords Four Crypto key sets Security access registers for each user zone Password/Key registers for each zone The CryptoRF command set is optimized for a multi-card RF communications environment. 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 particular application during the anticollision process.
