Description

The 6561 is a contactless R/W-IDentification IC (IDIC)* for general-purpose applications in the 125 kHz range. A single coil, connected to the chip, serves as the IC's power supply and bidirectional communication interface. Coil and chip together form a transponder. The on-chip 264-bit EEPROM (8 blocks 33 bits each) of 6561 can be read and written blockwise from a base station. The blocks can be protected against overwriting. One block is reserved for setting the operation modes of the IC. Another block can contain a password to prevent unauthorized writing.

Reading occurs by damping the coil by an internal load. There are different bitrates and encoding schemes possible. Writing occurs by interrupting the RF field in a special way.
