Overview ATA5590 is a wireless data carrier IC. The IC is powered by the RF field transmitted by an RFID reader. The carrier frequency is typically in the UHF region (860 MHz to 960 MHz). The functionality of the IC is controlled by the reader. The IC backscatters the required information back to the reader using a backscatter modulation technique; it is a passive UHF Transponder device based on the experience of the EU-funded project Palomar (IST1999-10339). ATA5590 was created to enable applications for open data management systems also supporting old or private data structures. Rev. 4817DS–RFID–12/05 Note: This is a summary document.
