I based the 65SPI on a Xilinx XC9572 CPLD. That part is not longer being manufactured and I only have a couple of those left in my stock. It is still available through distributors at a reasonable cost.

I was thinking that I should offer up a one-time, not-for-profit bulk order for these parts while they are still available.
Here's my offer:

I will purchase, program, and deliver 65SPI's for anyone who want them. Use an estimated cost of $7 each plus shipping. The actual cost will be announced after I get a chip count. You can use the USPS.COM website to get an estimate on shipping. Alternatively, you can email me and I can give you a shipping estimate. Payment can be made via paypal or money order. There will be a small fee for paypal, to partially cover the fees they charge me. Again, I am not trying to profit from this offer, I just want to cover my own expenses.

Feel free to ask any questions.

Full info on the 65SPI is located here:

I am no setting a due date at this time. If there is any interest, I'll set a date.

thanks!

Daryl

What package format are you using? PLCC?

I would be part of it. Details via P.M.

Yes, this is a 44 pin PLCC device. Thanks!

One more thing I want to mention. These CPLD's run on the warm-to-hot side. I have been placing a heat sink on mine to help. While they are not required, I highly-recommend their use.

This is the one I use:
http://www.digikey.com/product-search/e ... &x=11&y=15

I can include these in the bulk order also. If I order 10 or more, the cost should be about $6 each (includes the shipping and tax from digikey to me). Again, I can provide exact costs once I finalize the order.

I have already had 17 65SPI's requested. Thanks to all who have responded!

After this model of CPLD becomes unavailable, would you be moving the design to a different one? I don't know anything about it, but I would assume the transition would be pretty easy-- or is it that no others are available in thru-hole socketable packages like the PLCC?

What's an additional VIA among friends, anyhow?

I have not done any research into a new package. The Xilinx tools supported Abel - which I was familiar with. I'm not sure if a newer device will support that code or if it will have to be re-written in some other language.

I'm wondering how much trouble it would be to port it to Atmel's 150x series, which are in production. WinCUPl is a superset of ABEL, so it mostly would come down to the electrical side of things.

I'd be interested in two of them, each with a heat sink please.

Got you down for 2 - thanks!

Thanks to all who have requested parts.

I will set the final order date to Nov 15th. At that point, I will calculate the total cost for me to purchase the requested parts. I will then set the unit prices and let everyone know the exact cost and ask for their commitment to purchase. Once everyone acknowledges the request, I will purchase the parts, program them when they arrive, and package them for delivery. I will then request payment and send your parts out as I receive your payment.

My goal is for everyone to receive their parts by the end of the year.

Please contact me if you have any questions!

Thanks!!

Daryl

The XC9572 will still be available for a long time on ebay, where I usually buy components from.
So unless you want to be 100% sure that you want to buy a new and genuine component, you don't have to worry.

I had an opportunity to acquire 30 9572's at a good price. That is more than enough to cover the 20 that were requested so I made the purchase.

The price is $4.25 each! So, for those who have requested parts, I will have them in hand Nov 23rd and will be programming them as soon as they arrive. Please send me a confirmation message with your mailing address so I can get the shipping estimated ahead of time. I will have approximately 10 extra so if anyone else is interested, please let me know.

These are 44 pin PLCC parts with a 7ns speed rating.

Thanks all!

Daryl

I know this might be considered cheeky, but is the source code for this part available? I'm interested because I'm in the process of setting myself up for CPLD/FPGA dev and have some of these CPLDs on order. It would be great to learn how it works, and of course, to integrate one into my own computer.

No worries - and as "wmmullaney" already pointed out, its on my website. Let me know if you have any questions about the code.
