Chinese 68060

Hi there!

Has anyone experience with a MC68060RC80 or a MC68060FE133?

A 68060 running at 133MHz (or even 150MHz) sounds very nice :-)

Just Curious

There's no such thing. They're fakes.

How fake are they? 50MHz 060s that are relabel, or something else entirely that just had the size and pincount?

Who knows? The 68060 was only produced @ 50, 60, 66, and 75Mhz.

Could very well be 68LC060 or EC060.

Chinese fakes are far more common than the real thing (from China) and the bogus product numbers are self evident.

Fake ICs are very common from China through unofficial channels, and it's not just CPUs. Even simple logic ICs have been known to be faked and turn up on eBay regularly. It's not a new problem either, it was something that plagued component suppliers back in the '80s and '90s too.

What do you mean by "fake", is it not working, replica, lower specs?

Either cheap clones or rejects that don't behave quite like the originals. Sometimes they don't work, sometimes they appear ok at first but turn out to have some differences like outputs latching to the rails or having less tolerance than the originals and the spec sheet.

Note that Motorola/Freescale has never acknowledged the '68060FE133' as one of their products.

If it seems to good to be true....well....

Well, the worst example of a fake 68060 I have seen pictures of is a 68060 rev6 which was actually a 68040!
The size is the same so if only the top side is shown, which is the most common case, you can't tell that pins are "missing" until you receive the cpu!

Personally I've experienced a Chines fake for a USB-chip that cost $2!
But since there was a lover spec version of the same chip selling for $1, they made $1 for each lower spec chip they faked and sold as the higher spec version, and that was obviously enough to make it worth their while.

I have recived MOSFET's that obviously where chaper variants with higher RDSon and relabeled.

They worked, but got very hot, and measuring the resistance made it clear that they where way out of spec.
