Atmel Atmel CryptoRF® integrates a 13.56-MHz RF interface into Atmel CryptoMemory® to create a contactless secure RFID solution with advanced security and cryptographic features. The device is optimized as contactless secure memory for RF tags and secure data storage without requiring an internal microprocessor. This device contains 32Kbit of user memory and 2Kbit of configuration memory containing: 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 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.
