From: Aditi on 17 Mar 2010 19:09 Hi all, I am working on a new design and have chosen the Spartan 6 family FPGA for it. I was looking to see if there is a an on-chip PROM on any of the Spartan 6 FPGAs. I could not find about it in the datasheet. But if there is something that I am missing or if there is any other series of FPGAs with on-chip PROM, do let me know. Thank you, Aditi Akula.

Are you looking for a 'program once and it will always be there' memory or just something that has defined contents after configuration? If the latter then define a ROM and there are ways of setting the content during configuration. I'm mostly Altera these days so am a but rusty on Xilinx ram configuration but it's simple enough. Someone who knows the details should be along shortly.... Nial.

I think the OP wishes to see XC6SN (as non volatile) what isnt gonna happen, not soon at least Antti

Depending on what you need in your design, the Spartan-3AN (N=Nonvolatile) family may meet your needs. However, Spartan-3AN does not have an integrated memory controller nor does it have gigabit transceivers available in some Spartan-6 FPGAs. Spartan-3AN FPGAs are single-chip with integrated on-chip Flash memory, large enough for FPGA configuration plus extra. Spartan-3AN FPGA Family http://www.xilinx.com/products/spartan3a/3an.htm There are others as well, depending on your needs including Actel Igloo and ProASIC and SiliconBlue iCE65 FPGAs. It all depends on your requirements. -- Steve Knapp Prevailing Technology, Inc. www.prevailing-technology.com

Or for less than $2 you can get an SPI flash of whatever size you'd like in a TSSOP-8 or smaller package and not restrict your FPGA choice. -- Rob Gaddi, Highland Technology Email address is currently out of order |
