1. 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 experi-
ence 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.

UHF Transponder IC
ATA5590 contains the following top level blocks:
• The analog front end, which extracts
– the supply voltage for the IC from the RF beam
– the modulation dips transmitted by the reader
– the control signals indicating the status of the power supply
• The analog front end also contains structures for ESD protection, a low-power oscillator, and
a modulator stage.
• The digital front end, which extract status signals of the link as well as the extracted symbols
• A memory block which is implemented as an EEPROM containing an on chip HV voltage
generator to program the memory
• A register unit, which contains the transmitted commands and parameters
• A main finite state machine (FSM), which controls the frond end and the access mechanism.
• A random number generator, which is used to generate random values for the Aloha and
tree-walker-based anticollision procedures.
• Three different persistent nodes, which are able to store the status of the anticollision routine
over a certain time without any external power.
