Marking stuff with numbers letters and the like.

It's called "writing".

For the sake of dear old Freaky, what are you saying?

Well that's what cardboard boxes and plastic bags are for. Identify the product on these, the chip can be blank (as is probably desired).

Now say you made a widget.
And you wanted people to be able to identify it.

Let's say you made a widget.
And you didn't want people to reverse engineer it.
You [wouldn't want any | would remove any] writing on the internal components on said widget (especially ICs).

Now say you made a widget.

And you wanted people to be able to identify it.

You'd write sommat on it.

In this case it's a chip.

Which is marked inscrutably enough (because it's small) with "K100 M3" and a date code.

Now it transpires that this is an Infineon chip.

And this is the marking information that I've found:



on this page:

TDK5110 - Infineon Technologies



There must be a table somewhere that lets you correlate the device marking with the type, but I've yet to find it.

Ho hum.

It is the same chip, but I've had to confirm it by tracing stuff out.

There's nothing like making stuff easy for your customers.
