MICROCHIP AT88SC6416CRF-MR1

The Atmel CryptoRF family integrates a 13.56 MHz RF interface into an Atmel CryptoMemory, resulting in a contactless smart card with advanced security and cryptographic features. 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 Anticollision Protocol. Data is exchanged half duplex at a 106-Kbit per second rate, with a 2-byte CRC_B providing error detection capability. The maximum communication range between the reader antenna and contactless card is approximately 10cm 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 communication interface and a robust anticollision protocol. The Atmel AT88SC6416CRF contains 64 kilobits of user memory and two kilobits of configuration memory. The two kilobits of configuration memory contain: Eight 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.
