General Description


ATA5577 is a contactless read/ write identification IC (IDIC) for applications in 125-kHz or 134-kHz frequency band. A single coil connected to the chip serves as the

IC’s power supply and bi-directional communication interface. The antenna and chip

together form a transponder, or tag.


The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written

block-wise from a base station (reader).


Data is transmitted from the IDIC (uplink) using load modulation. This is achieved by

damping the RF field with a resistive load between the two terminals Coil 1 and Coil 2.


The IC receives and decodes serial base station commands (downlink) which are

encoded as 100% amplitude modulated (OOK) pulse-interval-encoded bit streams.

Full revision datasheet with enhanced data is available on request. Please contact

your local sales office.
