We'll tell you all you need to know to start evaluating and working with this product.

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.
