Traceability Data Structure
Block 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 the manu-
facturer’s ID of Atmel (= “15”hex). The following 8 bits could be used as UID issuer identifier
(UID Bit 47 to 40). If not otherwise requested, the 5 most significant bits (customer identification
CID) are by default reset (= 00) as the Atmel standard value (other values may be assigned on
request to high volume customers as CID) and the least 3 bits (ICR) are used by Atmel for the IC
and/or foundry version of the ATA5570.
The lower 40 bits of the data, encode the traceability information of Atmel and conform to a
unique numbering system. These 40 data bits are divided in two sub-groups, a 5-digit BCD
coded lot ID number (LotID - 20 bit) and the binary wafer number (wafer# - 5 bit) concatenated
with the sequential die number on wafer (DW - 15 bit).
