If you look at Renesas Electronics America’s ISL60002 series of voltage references, their top markings aren’t explained or broken down on their datasheet.
For example, you may see ISL60002BIH311Z-TK with a top marking of “SAWD”. This is the lot/traceability code. The “APM“ indicated on the datasheet would be on the bottom of the unit.
The parts’ datasheet shows the part marking information as follows:
