The Largest Selection of Memory Solutions for RFID
Atmel CryptoRF® is a 13.56MHz RFID (radio-frequency identification) device family equipped with a 64-bit embedded hardware encryption engine, mutual authentication capability, and up to 64Kbits of user memory. These low-cost chips are virtually impossible to copy and offer hardware security that is superior to software security solutions. CryptoRF ICs are ideal for applications that are prone to counterfeiting, require a permanent chain of ownership, or use contactless smart cards for cash transactions. They are also suitable for use in adverse environmental conditions where dust, dampness, or temperature extremes can cause problems for digital devices.
Key Features
- Safer than passwords — Mutual authentication between host and client is accomplished with a unique cryptogram that is randomly generated for each transaction.
- Attack isolation — The key diversification scheme limits any attack to only one unit.
- Multiple access levels — User memory can be divided into as many as 16 separate sections, allowing several different levels of read and write access.
- Diverse packages — The chips are available in many different shapes and sizes; tags in a variety of shapes can be developed for high-volume applications
- Host-side simplicity — The Atmel CryptoCompanion™ chip provides simple, plug-and-play authentication on a host (interrogator) device.
- Development tools — Comprehensive reference designs, demonstration kits, and application software facilitate implementation into existing products.

CryptoRF is the world's first 13.56 MHz RFID technology with a 64-bit embedded cryptographic engine, dual authentication capability, and up to 64 Kbits of memory — with up to 16 individually configurable sectors. CryptoRF product labels, tags, and cards are virtually impossible to copy and provide hardware security superior to any software solution. These low-cost security devices are ideal for applications that: are prone to counterfeiting (e.g., high-value consumer items and software); require a permanent record of the chain of ownership (e.g., tracking pharmaceuticals); or use contactless smart cards for cash transactions (e.g., bus passes and loyalty cards).

RFID reader
13.56MHz
ISO 14443 Type B |
The CryptoRF Reader Chip performs all RF communication, packet formatting, decoding, and communication error checking at the host. It is based on the ISO/IEC 14443-2 Type B signal modulation scheme and ISO/IEC 14443-3 Type B frame format, used by more than 60 percent of RFID host readers in the industry. Data is exchanged half duplex at a 106Kbps rate. A 2-byte CRC_B provides communication error detection capability. The chip can be used with both RFID transponders and contactless smart cards, and is compatible with 3.3V and 5V host microcontrollers with 2-wire or SPI serial interfaces. This highly integrated reader IC requires fewer external components than competing RFID reader chips, resulting in lower costs. It is available in one of the smallest packages available today: a 6mm x 6mm, 36-pin QFN.

Host-side security
Hardware security |
To validate the authenticity of a consumable or replaceable item (a client) when it is connected to a system (a host), there must be some secret information stored in both the client and the host. The CryptoMemory or CryptoRF chips provide a secure location to store this secret data in the client, while the CryptoCompanion chip stores the information in the host. CryptoCompanion provides plug-and-play host-side cryptographic security for embedded systems. This plug-and-play convenience means that designers do not have to design or test the cryptographic algorithms. The companion chip implements the necessary algorithms and the entire protocol completely in hardware. The chip is fully tested and guaranteed to work with all Atmel CryptoMemory and CryptoRF chips.
