ATA5567
1. Description
The ATA5567 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
pwowww.eDratsauShpepelty4Ua.cnodmbi-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
ATA5567 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.

Notes: 1. A common multiple of bit rate and FSK frequencies is recommended.
2. In PSK mode the selected data rate has to be an integer multiple of the PSK sub-carrier
frequency.

4.2 Tag to Reader Communication
During normal operation, the data stored within the EEPROM is cycled and the Coil 1 and Coil 2
terminals are load modulated. This resistive load modulation can be detected at the reader
module.
4.3 Regular-read Mode
In regular-read mode, data from the memory is transmitted serially, starting with block 1, bit 1,
up to the last block (for example, 7), bit 32. The last block which will be read is defined by the
mode parameter field MAXBLK in EEPROM block 0. When the data block addressed by MAX-
BLK has been read, data transmission restarts with block 1, bit 1.
The user may limit the cyclic data stream in regular-read mode by setting the MAXBLK between
0 and 7 (representing each of the 8 data blocks). If set to 7, blocks 1 through 7 can be read. If
set to 1, only block 1 is transmitted continuously. If set to 0, the contents of the configuration
block (normally not transmitted) can be read. In the case of MAXBLK = 0 or 1, regular-read
mode can not be distinguished from block-read mode.

Every time the ATA5567 enters regular-read or block-read mode, the first bit transmitted is a
logical 0. The data stream starts with block 1, bit 1, continues through MAXBLK, bit 32, and
cycles continuously if in regular-read mode.
Note: This behavior is different from the original e555x and helps to decode PSK-modulated data.
4.4 Block-read Mode
With the direct access command, only the addressed block is repetitively read. This mode is
called block-read mode. Direct access is entered by transmitting the page access opcode (“10”
or “11”), a single “0” bit and the requested 3-bit block address when the tag is in normal mode.
In password mode (PWD bit set), the direct access to a single block needs the valid 32-bit pass-
word to be transmitted after the page access opcode, whereas a “0” bit and the 3-bit block
address follow afterwards. In case the transmitted password does not match with the contents of
block 7, the ATA5567 tag returns to the regular-read mode.
Note: A direct access to block 0 of page 1 will read the configuration data of block 0, page 0.
A direct access to blocks 3 to 7 of page 1 reads all data bits as zero.
