Description
The AT88RF1354 is a smart, high performance ISO/IEC 14443 Type B RF Reader IC.
The AT88RF1354 communicates with RFID Transponders or Contactless Smartcards
using the industry standard ISO/IEC 14443-2 Type B signal modulation scheme and
ISO/IEC 14443-3 Type B frame format. Data is exchanged half duplex at a 106k bit
per second rate. A two byte CRC_B provides communication error detection
capability.
The AT88RF1354 is compatible with 3.3 V and 5 V host microcontrollers with two-wire
or SPI serial interfaces. In two-wire interface mode the AT88RF1354 operates as a
TWI slave and requires four microcontroller pins for data communication and
handshaking. In SPI interface mode the AT88RF1354 operates as a mode 0 SPI
slave and requires six microcontroller pins for data communication and handshaking.
To communicate with an RFID transponder the host microcontroller sends a data
packet for transmission over the RF communications channel, and receives the
response data packet that is received from the transponder over the RF
communications channel. AT88RF1354 performs all RF communication packet
formatting, decoding, and communication error checking. The host microcontroller is
not burdened with RF encoding, timing, or protocol functions since these tasks are all
performed by the AT88RF1354.
