: I guess the smallest spartan III and cyclone devices should also come down : below 10$ but then S3-50 does not have BRAM and both Spartan and Cyclone : do require config memory to be present what may add significant amount to : the final price (both money as board estate, etc)
XC3S50 _will_ have BRAM, only the first batch didn't have.

Hi Antti,
Have you used the Actel FPGAs? Are there free tools? Can the flash also be used to store additional data? Looks like a good candidate for a soft core cpu (as for JOP :-)

---------------------------------------------- JOP - a Java Processor core for FPGAs:
for this volume you will obviously need to contact the disti/factory but for the Cyclone the quantity 50K pricing from the disti as below. better deals may be found I suspect if the volume goes up a bit and in
2004 ...EP1C3 $5 , EP1C4 $11 , EP1C6 $13 , EP1C12 $27 , EP1C20 $60
down
to
without
The cheapest way for the configuration is using a standard flash and a small PLD (like max7032 or max7064) and you can use the rest of the flash for other data (like program for a soft core cpu).

The Xilinx Spartan-3 XC3S50, in its production form, has four 18Kbit block RAMs (BRAM), four 18x18 hardware multipliers, and two digital clock managers. For the correct specifications, see
In volume, the XC3S50, the XC3S200, and the XC3S400 are all less than $10 in the smallest packages.
To reduce the overall "solution cost", Spartan-3 FPGAs optionally use Xilinx PlatformFlash, which does NOT add a significant amount to the final price. See
