- 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...
