Hi,
is any spartan FPGA is in PLCC package?also its availabilty ?
I want to use spartan series FPGA & not the any other spartan seris
like spartan 2e etc.
which sprom should be used?

I've got some Spartan XL chips in PLCC somewhere. They are probably
still available from Farnell, as well as the configuration devices.

Leon.

i want to design the prototype board for spartan
series FPGA which is
least costly,for master serial mode of configuration i want to use
PROM.I am looking for some through hole component like PLCC84 pin &
PLCC 20 pin package.can u suggest me some.

PLCC stands for Plastic Leadless Chip Carrier, so
it is NOT
through-hole.
But there are sockets that can convert PLCC to through-hole.
Don't expect any modern devices in this package. Too big and too few
pins for today's designs.
The world changes, not always in the direction one likes...

Least costly:
   Buy a development board for $99.

Alternative for "your own" stuff:
   Use a new FPGA - Xilinx Spartan3(E?), Altera Cyclone-II, or Lattice 
ECP(2?) - in a TQFP package (still solderable by hand).  It's not 
through-hole but it's doable.  Good through hole support is mostly a memory.


And don't force everything to be 5V.

PLCC stands for Plastic *Leaded* Chip Carrier.  It has J-leads, like an
SOJ, but around a square package rather than down two parallel sides.

True.

Sorry, you are right, of course. Really
ambarrassing...
But it does not change the fact that they are NOT through-hole.

The PLCC Spartan/SpartanXL is NOT going to be the
least costly.

Xilinx no longer supports them.  To synthesize, you'll need FPGA
Express, and the last time I checked, it ran about $15,000.00 - 15K
will buy a lot of time at your local stuffing house.

Hi,

 I thought one can synthesize for Spartan and Spartan XL with Icarus
Verilog then tranfer EDIF file to ISE Classic to complete the project.
 Am I wrong?  
 By the way, the advice here stands too true.  Don't start a new
project with devices not supported by ISE WebPACK just because you
can buy them cheap...

 Satoru

You are right, although the -tfpga target for 0.8 is a little rusty
compared to current CVS of v0_8-branch, and -tfpga is non-functional
on the devel trunk. Because the main trunk and synthesis have diverged
recently, I've been considering keeping synthesis in the v0_8 branch
and fixing/maintaining it there. A fork, if you will.

And supporting abandoned parts like this is a excellent use of open
source software. Might even be a business opportunity;-)
