Impossible to do it in 30k. Unreasonable to buy FPGA with less than
200k. You are the one asking for FPGA. Have you find any ARM with FPGA
for less than $100? You are not only asking for ARM, but ethernet,
Sdram, CF and custom FPGA gates.
Have you guys really look into the FPGA market?

These are also nice. Thank you!
I agree, there seems to be tendency to overkill. The whole ARM core is
30k transistors; 1mil gates FPGA for $hundreed(s) just to immitate ARM
core for 5 bucks ... nonsense
Anyone selling an ASIC, something like AT91SAMX but bundled with PHY ?

What do you mean by phantasy? There are actual soft ARM cores in 200K,
PPC cores in 300K FPGAs. What do you think the micro manufacturers use
for prototypes?
1M gates FPGA is mid-range. 5M gates can be yours, if you send us a
cashier check.

Hi,
thought I would post another real answer to the original question, not
some phantasy posting about 1Mio gates FPGA.
Have a look here:

It's possible, but not very effective use of routing area with DIP 40.
A 100 mils square PGA (pin grid array) would be better. It's just as
easy to prototype as a DIP.

Then may I suggest a soft-core 1 million gates FPGA with
1. Arm 7
2. 10/100 ethernet
3. SDRAM (DDR or SDR) controller
4. CF/xD interface for booting and ATA
5. USARTs
6. 300K free gates for your custom design
in a 12mmx12mm Fine pitch BGA, or we can mount it on a 100 mil PGA
(17x17 dual rows) for you.
It would be in the $99 range, depends on QTY.

That's great. AT91SAM7X does not need FPGA for boot, of course. FPGA is
for configurability. Need interfacing CF or SD, various protocols my
customers invented ... But for most applications is may just be
chilling there powered down :)

Also has built-in 1.8V regulator.
And just for the record of this thread to keep the topic - I located
another one from www.netburner.com using 66MIPS ColdFire. No ethernet,
no programmable logic, just another one of those DIP adapter types. But
the ColdFire chip they used seems to have all the bells and whistles of
Atmel AT91SAM7X.

Yes, but the CPU must be able to run without the FPGA. I.e. not using
the FPGA for CPU glue logics. Anyway, what are you using the FPGA for?
Also, don't forget voltage regulators, 3.3, 2.5 for XC2, 1.8 for XC3
and ATSAM
