For the TMP chips, there is the EEPROM1 register which is a unique ID for NIST traceability. Can you tell me how the tracing topology works? I recently did multiple parts and found they can have the same ID, but parts I think from different reel had a different ID. Is this ID unique to a wafer lot? If in future, we have issue, and need to trace back to this NIST ID, what will this information give us when we present it to you?
