Again hard data lacks..
(specific chip and package, specific Mbit/s rate, specific electrical standard etc)


From the product webpage: Spartan 6 LX9 FPGA

In the datasheet they link to, there is only one LX9, XC6SLX9

While I'm not at my Eagle computer right now, I'm sure the Eagle layout/board file will show which package they used. The UCF gives you an idea of clock speed:
NET CLK            LOC="P94"  | IOSTANDARD=LVTTL | PERIOD=31.25ns;               # CLK

Methinks the detective in you didn't try very hard...

The other board someone linked to, Pipistrello, says 324BGA with LX9, LX16, LX25 or LX45 options. I suppose that's simply a list of chips in that same 324BGA package.

Actually MikeJ, perhaps you could develop an FPGA hobby board, for first time devs who want to get their feet wet ;)


That's kindof what his board is...
