Is there a Lattice Semiconductor engineer or e-mail address here-abouts? I'm looking for the answers to the following: What's the difference between a GAL16V8 and a GAL16V8A? What are the product term disable fuses useful for? (Other than the obvious... why are these in the architecture? do they alter the speed/power dissipation?) Why is the architecture configuration still accessible after programming the security fuse? It seems to me that this saves a few hours for the buggers off-shore (or on-shore!) that are going to reverse engineer my product! And finally... why is the 16V8 so much cheaper than the 22V10? A factor of two seems reasonable to me, but 4-6x seems excessive. I've been putting in two 16V8s instead of a 22V10 in most cases, and am happy to continue to do so, but it seems to me that there would be more profit for Lattice if the 22V10 came down some. Thanks for your time... James MacPhail jmacphai@cue.bc.ca james@mirg2.phy.queensu.ca
