I'm not trying to be a troll but how do you know that the Chinese manufacturers of the clones (NOT the remarks) didn't licence it? STMicroelectronics does have offices all over the world including China. Is there proof the clones (NOT remarks) are non-licensed and not just speculation based on the feeling "China always counterfeits"? One thing I didn't check was the date code which may tell but I don't have any of the parts in front of me. Again, not trying to be a troll because I will be the first to admit I don't know squat about parts licensing. Thanks, - Commander Dave
There's a good chance they're just refurb'ed socket pulls as well...
China is a huge destination for "recycling" and a lot of their IC stock comes from cleaning up stuff taken off those "recycled" pcbs.
I bought a small quantity of these "new" ST chips from China to check out, and you are absolutely correct. They are refurbished chips. They have gotten very good at this.... Legs are straightened, flared out (to give that "NOS look"), and refinished (giving them a satin appearance). Bodies are washed of all previous markings (probably using acetone) and all stamped with the same identical fake ST markings. If you look very closely at the legs you will find anomalies; some slightly slanted, out of alignment with each other, and even some twisted a bit. And I found some issues with the refinishing as well. Anyone who has ever bought real NOS chips before knows that they come absolutely perfect. Oh, and another clue that they're not legit; they come in unmarked tubes.
It's too bad really.... For the price they are asking, I'd gladly pay for pulls with their original markings. It's unfortunate that they feel the need to be deceitful.
I've bought a LARGE quantity of these and the following doesn't match my experience.
I have same issue with the 2764s I bought. Fail ID test on my elnec ... but topic of this thread is 2716 and these have no such issue.Checked the chips out electronically today. They are stamped "ST M27C64A", but the manufacturer ID read from the chip does not match ST... comes back as National.

Yes, the original question was about 2716. But the discussion has revolved around the legitimacy of all these remarked "ST" chips coming out China, whether they be 2716, 2732, 2532, 2764, 27256, etc. I don't have a need for any 2716, so I'm not going to bother buying any to check out. But I have personally seen the 2732 and 2764 "ST" parts now. They are all cleverly refinished parts masquerading as new. And the pictures I've seen of the 2716 parts lead me to believe they are no different. Maybe some of them actually were originally ST parts, but none of them are NOS or new "clones" (which is ridiculous). These restamped parts are all reclaimed chips that have been refurbished by the Chinese recyclers. Have yet to see any evidence to the contrary.
Not an expert, just my 2 cent observation. -Dave
Just got in 10 ST M27C801's from China. Die's are identical, chips look identical, appear new to my non-bulk buying eyes, all checked out fine as far as the device ID matching for an ST M27C801.
Those look like the legit ST M27C801s that I purchased 15+ years ago.Just got in 10 ST M27C801's from China. Die's are identical, chips look identical, appear new to my non-bulk buying eyes, all checked out fine as far as the device ID matching for an ST M27C801.
I asked one of the sellers of about the origins of the M2716A EPROMs and other counterfeit looking parts. Calls it "China copy".
