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...

Communications All personalization and communication with this device is performed through the RF interface. The IC includes an integrated tuning capacitor, enabling it to operate with only the addition of a single external coil antenna. The RF communications interface is fully compliant with the electrical signaling and RF power specifications in ISO/IEC 14443-2:2001 for Type B only. Anticollision operation and frame formatting are compliant with ISO/IEC 14443-3:2001 for Type B only. ISO/IEC 14443 nomenclature is used in this specification where applicable. The following abbreviations are...

User Memory The EEPROM user memory is divided into four user zones as shown in Table 6-1. Multiple zones allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been met. These security requirements are defined by the user in the configuration memory during personalization of the device. The EEPROM memory page length is 16 bytes. Table 6-1. Configuration Memory The configuration memory consists of 2048 bits of EEPROM memory used for storing system data, passwords, keys, codes, and security-level...

Communication Security Communication between the PICC and reader operates in three basic modes: Standard Communication Security Mode — The default mode for the device after power-up and anticollision. Authentication Communication Security Mode — Activated by a successful authentication sequence. Encryption Communication Security Mode — Activated by a successful encryption activation sequence, following a successful authentication. Configuration Security Modes Communication Mode User Data System Data AT88RF04C supports an encryption option for programming secrets. Security Methodology Figure...

Security Operations Anti-tearing In the event of a power loss during a write cycle, the integrity of the device’s stored data may be recovered. This function is optional — The host may choose to activate the anti-tearing function depending on application requirements. When anti-tearing is active, write commands take longer to execute since more write cycles are required to complete them. Data writes are limited to 8-byte pages when anti-tearing is active. Data is written first to a buffer zone in EEPROM instead of to the intended destination address, but with the same access conditions. The...

Initial Device Programming CryptoRF is delivered with all security features disabled. To program the polling response or enable the security features of CryptoRF the device must be personalized by programming several registers. This is accomplished by programming the configuration memory using simple write and read commands. AT88RF04C supports an optional Secure Personalization mode which encrypts the secrets during programming. Transport Password To gain access to the configuration memory, a transport password known as the secure code must be presented using the Check Password command. The...
