Description

The AT88RF020 is a low-end 13.56 MHz RFID (Radio Frequency IDentification)

device that includes an on-chip EEPROM-based (nonvolatile) memory. The wireless

interface complies with Type B operation of ISO/IEC 14443. The specific sections of

compliance are 14443-1, as well as 14443-2:1999(E) (dated 5/2/00) and 14443-

3:2000(E) (dated 7/13/00).

AT88RF020

This device is designed to be used in applications where one or more RFID devices

will be simultaneously placed within an intelligent reader/writer RF field. Communica-

tion between the RF reader/writer and this device will take place through the use of

the featured anticollision command set supported by this device.

The memory contains a total of 2048 bits, organized as 32 64-bit pages. Write opera-

tions are designed to complete in less than three milliseconds (ms). The endurance

rating for the memory is 100,000 write cycles per byte.

This device supports these security features: password checking, data locking, a one-

way counter and a guaranteed unique serial number.

The AT88RF020 includes an on-chip internal tuning capacitor that enables it to oper-

ate with a single external coil antenna. This antenna completes the RFID channel.
