I just want 5 volt I/O!
Ben.
Trust me, I feel your pain, but this ship sailed too :(
I enjoyed the time, when one was developing stuff,
where pretty much
most of the stuff on the board was 5V, and they came from a backplane
anyway ...
Now, 30% of the design effort & time is power supply (1v0, 1v2, 1v8,
2v5, 3v3 and 5v).
Yes I have a Spartan 3E Sample Pack board and was looking to use
it to
build a Strobe for timing my Teletypes so was looking at the power to
see how much drive I could get. I was amazed to find the PSU is the most
complex part of the circuit with 3 x ICs, three filters ....
Going back, dreaming ;-)
