XRA00

The XRA00 is a full-featured, low-cost integrated circuit for use in radio frequency identification (RFID) transponders (tags) operating in the UHF band of frequencies. It is a 128-bit memory, organized as 8 blocks of 16 bits, as shown in Figure 3. When connected to its antenna, operating power is derived from RF energy produced by the RFID reader. The XRA00 non-volatile memory enables users to program tags at the point of application, if desired. The XRA00 will respond only after first receiving a valid and appropriate command from the reader.

Based on the EPCglobal class 1b specification, the device provides a fast and flexible anticollision protocol that is robust in the noisy and unpredictable RF conditions that are typical of RFID applications.
