T5577 Proximity Card with 125KHz Frequency Read & Write Function and White PVC Material for Access Control

1. General description

The ATA5577 is a contactless read/write identification IC for applications in the 125-kHz or 134-kHz frequency band. A single coil connected to the chip severs 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 (11blocks 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 strams.
