TMEIC5567 Card

The T5567 is a contactless R/W IDentification IC (IDIC) for applications in the 125KHz frequency range. 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 330-bit EEPROM (10 blocks,33 bits each) can be read and written block-wise from a reader. Block 0 is reserved for setting the operation modes of the T5557 tag. Block 7may contain password to prevent unauthorized writing. Data is transmitted from the IDIC using load modulation.
