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. Figure 1.
