Description The ATA5577 is a contactless read/write identification IC (IDIC ) for applications in the 125-k Hz or 134-k Hz frequency band. A single coil connected to the chip serves as the IC’s power supply and bi-directional munication 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 mands (downlink), which are encoded as 100% amplitude modulated (OOK) pulse-interval-encoded bit streams. ..
