Freescale do not want to sell anymore 68060 chips. They want to move all new designs over to the coldfire platform.
Why?
Pure speculation, but as a chip engineer, I think it is probably because they can no longer make 68060 chips in their own factories. The Freescale fabs (factories that makes chips) probably do not make chips of that geometry any more.
Why not just "End of life" the 68060 and stop selling them all together?
Again, pure speculation, but I think it is because they were sold directly from Freescale (then Motorola) to the military. Military ASIC contracts demand that any chip used must be continued to be sold for (I think) at least 25 years from the date of first purchase.
So, unable to make anymore than they have in Inventory what do they do? They up the price to something stupid, a price so high that only the military will buy them, that should see them through to EOL.
There is someone else, other than Freescale, still making and selling 680x0 CPU's.
