CryptoRF Reader Chip
CryptoRF Reader Chip AT88RF1354, performs all RF communication, packet formatting, decoding, and communication error checking and 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% of the vendors of RFID host readers. Data is exchanged half duplex at a 106k bit per second rate. A two-byte CRC_B provides communication error detection capability. The AT88RF1354 can be used with both RFID transponders and contactless smart cards and is compatible with 3.3V and 5V host microcontrollers with two-wire or SPI serial interfaces. The highly integrated reader IC requires fewer external components than competing RFID reader chips, resulting in a lower BOM and is available in the smallest package option obtainable today - a 6mm x 6mm, 36-pin QFN.
