Someone here forgot to do a lifetime buy from them in time but we recently did a lifetime buy of several thousand from a third party company. In the first production run of over 100 boards, every single one failed the manufacturing test. It seems at least one of the problems is when it tries to access internal memory from external memory it gets zeros - or something like that (don't have the exact details). We suspect the chips are counterfeit or seconds or something. > > Has anyone heard of this kind of problem? > > Does anyone know a reliable source of H8S2676 chips? > Can't be of any help but thanks for sharing the info. Can you perhaps name the third party company, this might help other people in the future. I have not been burned yet but I have heard plenty of stories about chips bought not via the large, known distributors. There looks to be quite a busyness living on selling you "whatever you need, we'll just have to imprint the logo on a fitting package". OTOH we bought some fast HV diodes via ebay twice (not sure if it was the same seller both times), were OK.
