2. 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.
