rfid security protection rewritable card

The T5577 is a contactless R/W IDentification IC (IDIC®) for applications in the
125-kHz 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 blockwisefrom a reader. Block 0 is reserved for setting the operation modes of theT5577 tag. Block 7 may contain a password to prevent unauthorized writing.Data is transmitted from the IDIC 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 100% amplitude-modulated (OOK) pulse-interval-encoded bit
streams from the base station or reader.Multifunctional 330-bit Read/Write RF Identification IC T5577 4874D
