Need just a few 5V Spartan

Started by Jon Elson October 31, 2006
Hello, all,

Does anyone know where I can get just a few (5 - 10) Xilinx
XCS30-3TQ144C chips?  Anybody who has them wants to sell me
a minimum of a hundred or more.  I just need a few to make
repairs on equipment in the field.  I just got a board back
from a customer who had a lightning strike, and I had to salvage
a chip off a test module to get his unit repaired.

If anyone has a few of these chips laying around, I'd be glad to
pay the going rate for them, too!  I can probably use other speed
ranges or temp ranges as well.  I'm in the US, but that shouldn't
make much difference, I seem to be buying my Xilinx chips from
Australia these days!

Thanks much in advance.

Jon

This is again a case for the Xilinx "online shop"... -- Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------
Have you tried the distributors, including DigiKey?

For the 5 Volt Xilinx series, none of the part is on stock at Digi, and all have quite high minimum order -- Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------

XCS30XL-4TQG144I (or C) are both in stock at Digikey but the -3 speed grades have the 60pc minimum order. Can you get by with the different speed grade?

Digi-Key has NO stock of 5 V Spartan parts. They will gladly order some if I place an order for only 60 parts. That's a $2178 order! This is what I get from a number of "stocking" distributors. Digi-Key dropped the 5 V Spartan line about 2001, I think. Somebody else mentioned the Xilinx store. They don't sell chips, period, as far as I can see. They have links to their franchised distributors, but there is no link at all for Spartan, or Spartan 2 or 2E. Only Spartan 3 and 3E. Jon

Spartan XL is not the 5 V Spartan, it is 3.3 V, and not pin compatible with 5 V Spartan. These chips will not work without major changes to the board. I am doing that, but going to XCS2E. It is a complete from-scratch redesign. Jon

Have you tried www.findchips.com ? plenty of hits on a search for XC2S -is this the correct family?

Consider using XC3S...E. Why stick with XCS2E? -- Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------

My reasoning, at the time this redesign started was based partly on price, the I/O voltages supported, and the size of the ROM needed to download the FPGA. This product has no CPU or other ROM on board. I finally figured out how to use an SST serial flash memory that is incredibly cheap. 1 Mbit for $1.85, and it takes 2 little CMOS chips to get the ROM to start dumping its contents. Maybe I made a mistake, but this product uses a pretty small FPGA by today's standards. I can get the XC2S50-something-TQ144C for $12, I know how to mount it to a board myself, etc. A number of the newer stuff is in packages I at least am not so sure I can handle. Jon
