Honored ContributorHi,
I have a question about configuration pins voltage choice. please help me. The configuration pins of the Cyclone IV I use is located at Bank3, which also includes DDR2 pins. So I set the bank3 IO voltage to 1.8V. However,the MSEL pins is required to set 2.5V,3.0V,or 3.3V in AS fast mode in handbook. What voltage level the MSEL pin should set?
Honored ContributorHave you checked page 8-8 of the Cyclone IV manual? It has a bit on there about different voltages and configurations for Active- and Passive serial..

The AS mode in Table 8-4 just includes 3.3,3.0,and 2.5V, not lists 1.8V, however, the note 1 said that Configuration voltage standard applied to the VCCIO supply of the bank in which the configuration pins reside. I am confused whether 1.8V is feasible or not.Honored ContributorHave you solved this confusion? I get the same problem.
