I/O Standard

Hello, recently while working on a design with EP4CE30F29I8LN where all our I/O banks were powered to 3.3V and under device and pin options I had selected 3.3-V LVCMOS. However one of the I/O lines...

Hello Divakar,

I see you are using Cyclone IV on your design. Are you referring to Vccio? If yes, the range of Vccio in 3.0-V LVCMOS is from 2.85V to 3.15V. Supplying Vccio of 3.3V on this bank is not recommended since it is above the range and I cannot validate whether it will be safe or not to your device. I would recommend you to follow I/O Standard Specs from Cyclone IV Device Datasheet Table 1-15 page 12: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-iv/cyiv-53001.pdf .

Thank you.

Is there a way I can get current strength greater than 2 mA when selected for 3.3-V LVCMOS
