counterfeit chips are like compiler bugs: they are incredibly easy for newbies to spot.
Oh that explains why I have found so many compiler bugs! :lol:

my guess is, it is probably more difficult and more expensive to make even clone , compatible or for that matter 'fake' chips compared to simply buying the real ones, unless of course if the fake chips totally doesn't work and are simply duds :lol:

I would think it unlikely that the STM32F103XXX that we see are clones or copies, since that would imply some pretty sophisticated entity had cloned them.

However they might conceivably be "recovered" in some "hot wok" chip recovery enterprise in the back streets, from some common consumer grade product(s).

Given that they have a relatively low value, I would suggest that there are much better things to clone, with much broader appeal (Nike trainers for example).

Or they are surplus parts from a project, bankrupt sales, recovered parts, or simply from someone who is more efficient or wants to use this for marketing purposes, ..... The list goes on and on.

The issue with the "counterfeit!" Clamants is that once they rule every other possible explanations, they are left with 120 percent sure that anything priced lower than what digikey or arrow charges for the same part is a counterfeit.

Only if they understood what it took to counterfeit something like a 32bit chip, ....
