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).
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.
