Part Number: ISO7762

Hello,

can anybody please explain me how to read the LOT or Date Code marking on the ISO7762 package?

What does "04C4CDT" mean?

Thanks in advance,
Niels

    Hello Niels,

    Thank you for your question. The general format of the lot code is YMLLLLS, where Y refers to the year, M is the month, LLLL is the assembly number, and S is the assembly site. This means that the chip you have was manufactured in April of 2020. I'm also attaching a document below that explains in more detail how to interpret lot codes for your reference.
