The CryptoRF™ family integrates a 13.56 Mhz RF interface into a CryptoMemory^®, resulting in a contactless smart card with advanced security and cryptographic features.This device AT88SC6416CRF is optimized as a contactless secure memory, for multiapplication RF smart card markets, and secure identification for electronic data transfer, without the requirement of an internal microprocessor.  

For communications, the RF interface utilizes the ISO 14443-2 and -3 Type B bit timing and signal modulation schemes, and the ISO 14443-3 Slot-MARKER Anticollision 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 14443-2 RF power level. The RF interface powers the other circuits; no battery is required. Full compliance with the ISO 14443-2 and -3 standards results in anticollision interoperability with the AT88SC6416CRF 2-Kbit RFID EEPROM product and provides both a proven RF communication interface and a robust anticollision protocol.

The AT88SC6416CRF contains 64 Kbits of user memory and 2 Kbits of system memory. The 2 Kbits of system zone memory contain eight sets of read/write passwords, four crypto key sets, security access registers for each user zone, and password/key registers for each zone. The features and functionality of the system zone are identical to those in the standard CryptoMemory.

The CryptoRF command set is optimized for a multicard RF communications environment and includes all of the functionality of the standard CryptoMemory commands. A programmable AFI register allows this IC AT88SC6416CRF 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.
