10 years agoHi, you can share a source on the VCCIO of multiple banks which required the same voltage level for each I/O bank. The shared I/O pins can only support a VCCIO range of 1.5V to 3.3V.
You may refer to Max 10 Pin Connection Guidelines for more understanding about the VCCIO. https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/max-10/pcg-01018.pdf
