ISO7762: ISO7762 LOT / Date Code marking

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.
