Description

The CryptoRF® family integrates a 13.56 MHz RF interface into a 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/s rate, with a two-

byte CRC_B providing error detection capability. The RF interface powers the other

circuits; no battery is required. Full compliance with the ISO/IEC 14443-2 and -3

standards and provides both a proven RF communication interface and a robust

anticollision protocol.
