Honored Contributor --- Quote Start --- im using the EP1C3T100C8N, but only actually using 14 IO pins so two banks are unused --- Quote End --- p253 has the statement I recall: http://www.altera.com/literature/hb/cyc/cyc_c5v1.pdf "Normal operation does not occur until both power supplies are in their recommended operating range" --- Quote Start --- I think i will power the other two banks any way, im not saving any thing by not powering them just a little bit extra routing lol --- Quote End --- That would be my advice.
