Description

The AT88RF001 is a stand-alone 13.56 MHz RFID front end that includes a serial port

suitable for connection to an external high-density serial memory. Using the on-board

EEPROM, it can be configured to communicate using various protocols and interface

to both two-wire and SPI external devices.

Interface IC

AT88RF001

The device contains 320 bits of full read/write EEPROM memory and offers features

such as passwords, locking and a variable-length ID. It is electrically compatible with

ISO/IEC 14443-2, Type B. The IC includes an internal tuning capacitor; only an exter-

nal coil antenna is required to complete the RFID channel.

The serial channel is configurable to communicate with external ICs using either two-

wire or four-wire (SPI) serial channels, at a maximum speed of 106 kilobits per second

(Kbps). An external bypass capacitor will be required to filter and stabilize the supply

generated by the RFID front end. Up to 2 mA can be drawn by the external memory

when communications are not occurring.

Modulation

The AT88RF001 is intended to be used with serial EEPROMs such as Atmel’s

AT24Cxx two-wire line or its AT25xx SPI line. In addition, it can communicate with an

external microprocessor if more complicated systems are to be built, if software on

that processor can model the slave protocol of the corresponding memories. It is

expected that a single external memory chip will be connected to the AT88RF001.
