Well, we needed a full industrial (-40°C to +85°C) video controller to
use with an MPC8250. We selected the Eposn S1D13806. We ran
production for just over a year, and then Epson discontinued it
without notice. I hate it when that happens. It's a shame, because
it had integrated SDRAM. It was the perfect single-chip solution for
our application.
Now we are in the same boat of looking for a suitable replacement,
with full industrial specs. And by the way, we don't want a PCI
interface. We are thinking that we will have to use an
FPGA+SDRAM+video DAC, but this is going to use more real estate. Any
ideas?
Coral-P, Coral-Q ?

On second thought, the Coral-B looks better. It's in a BGA package,
so I can afford some real estate for external SDRAM. Also, the QNX
web site says that they have a PowerPC driver for the Coral-B.

Fujitsu's North American distributor is Arrow. At this time Arrow
does not show any of the Fujitsu graphics controllers in their online
database. We'll have to call to see what the availability is like.

there is one but, it costs as much as powerPC itselfe :)

It certainly is overkill, but:
The BGA package uses much less real estate than the PQ208 used for the
Scarlet. Board space is critical for us.
The Coral has a 1.8V core voltage, same as the PowerPC that we are
using. The Scarlet needs 2.5V, so we would have to add another
regulator.
Fujitsu is making sure there is wide embedded OS support for Coral, so
it seems likely to be around for a while.
We foresee some applications where the video input will be a good
feature.
When all is said and done the Coral looks like it makes more sense for
us.
