Traceability Data Structure
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
Atmel.
Figure 3-3.
Blocks 1 and 2 of page 1 contain the traceability data and are programmed and locked by Atmel
during production testing
class (ACL) as defined in ISO/IEC 15963-1. The second byte is therefore defined as Atmel
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.
