T5577 LF contactless  card  125 Khz

    The ATA5577 is a contactless read/write identification IC (IDIC®) for applications in the 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).
