LVCMOS12_LVAUX is an LVCMOS standard. See the LVCMOS section in UltraScale Architecture SelectIO Resources User Guide (UG571) for information on how LVCMOS standards typically function. Except for the differences highlighted in this section, LVCMOS12_LVAUX functions the same way as LVCMOS12.
- LVCMOS12_LVAUX is only available for HP I/O banks.
- LVCMOS12_LVAUX only has a drive strength of 8 mA. Unlike the other LVCMOS standards, it does not support drive strengths of 4 mA or 12 mA.
