Preliminary
1. Description
The ATA5570 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 block-
wise from a reader. Block 0 is reserved for setting the operation modes of the
ATA5570 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 COIL1 and COIL2. The IC
receives and decodes 100% amplitude-modulated (OOK) pulse-interval-encoded bit
streams from the base station or reader.
