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.
