Identification IC
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.

3.11 Memory
The memory is a 330-bit EEPROM, which is arranged in 10 blocks of 33 bits each. All 33 bits of
a block, including the lock bit, are programmed simultaneously.
Block 0 of page 0 contains the mode/configuration data, which is not transmitted during regu-
lar-read operations. Block 7 of page 0 may be used as a write protection password.
Bit 0 of every block is the lock bit for that block. Once locked, the block (including the lock bit
itself) is not re-programmable through the RF field.
Blocks 1 and 2 of page 1 contain traceability data and are transmitted with the modulation
parameters defined in the configuration register after the opcode “11” is issued by the reader
(see Figure 4-6 on page 11). These traceability data blocks are programmed and locked by
Atmel.

3.12 Traceability Data Structure
Blocks 1 and 2 of page 1 contain the traceability data and are programmed and locked by Atmel
during production testing(1). The most significant byte of block 1 is fixed to E0h, the allocation
class (ACL) as defined in ISO/IEC 15963-1. The second byte is therefore defined as Atmel®’s
manufacturer ID (15h). The following 8 bits are used as IC reference byte (ICR bits 47 to 40).
The 3 most significant bits define the IC version of the ATA5567, the foundry version, or both.
The lower 5 bits are by default reset (00) as the Atmel standard value. Other values may be
assigned, by request, to high volume customers as tag issuer identification.
The lower 40 bits of the data encode Atmel’s traceability information, and conform to a unique
numbering system. These 40 data bits are divided in two sub-groups, a 5-digit lot ID number,
and the binary wafer number (5 bits) concatenated with the sequential die number per wafer.
Note: 1. This is only valid for sawn wafer “DDB, DDT” delivery.

4.9 Password
When password mode is active (PWD = 1), the first 32 bits after the opcode are regarded as the
password. They are compared bit by bit with the contents of block 7, starting at bit 1. If the com-
parison fails, the ATA5567 will not program the memory, instead it will restart in regular-read
mode once the command transmission is finished.
Note: In password mode, MAXBLK should be set to a value below 7 to prevent the password from being
transmitted by the ATA5567.
Each transmission of the direct access command (two opcode bits, 32-bit password, “0” bit plus
3 address bits = 38 bits) needs about 18 ms. Testing all possible combinations (about 4.3 billion)
would take about two years.
4.10 Answer-On-Request (AOR) Mode
www.DataSheet4U.com
When the AOR bit is set, the ATA5567 does not start modulation in the regular-read mode after
loading configuration block 0. The tag waits for a valid AOR data stream (wake-up command)
from the reader before modulation is enabled. The wake-up command consists of the opcode
(“10”) followed by a valid password. The selected tag will remain active until the RF field is
turned off or a new command with a different password is transmitted which may address
another tag in the RF field.
Table 4-2. ATA5567 — Modes of Operation
PWD AOR Behavior of Tag after Reset Command or POR
Answer-On-Request (AOR) mode:
1 1 • Modulation starts after wake-up with a matching password
• Programming needs valid password
Password mode:
1 0 • Modulation in regular-read mode starts after reset
• Programming and direct access needs valid password
Normal mode:
0 -- • Modulation in regular-read mode starts after reset
• Programming and direct access without password
De-activate Function
Command with non-matching password
deactivates the selected tag
