 		 #122521 - There are "family" data sheets that are adequate
Responding to: ???'s previous message
These datasheets provide configuration information. By that I mean ALL the configuration modes available.

By far the lowest cost and easiest is the new mode provided by the new Spartan3E series. I'd suggest you look that one up as it uses standard serial flash devices.

take a look at

http://www.xilinx.com/bvdocs/pu.../ds312.pdf

and then look for configuration options within that document. This will tell you about the various ways in which you can configure this family of devices. It has a serial (SPI) configuration option not available in earlier FPGA families. However, it's a good idea to keep in mind that the configuration PROM requirements for FPGA's in this range from 581,344 bits for the XC3S100E to 5,969,696 bits for the XC3S1600E.

Go ahead! Have a look! That's the best way to find out how this all fits together.

            Every bit of it is on their website!            01/01/70 00:00      
         been there, done that            01/01/70 00:00      
            do they still make FPGA's that small?            01/01/70 00:00

                  a colleague said, \"the gates are free\"            01/01/70 00:00      
                     maybe for small parts            01/01/70 00:00      
                        depends on where you get pricing            01/01/70 00:00

                        Well, most 805x's run at 5 Volts ...            01/01/70 00:00      
                           well, nope            01/01/70 00:00      
                              depends on how you use 'em.            01/01/70 00:00      
                                 do you read the posts or just the titles?            01/01/70 00:00      
                                    Yes, I read 'em, but that doesn't make it so ...            01/01/70 00:00
