Table 2–4. MAX II I/O Standards
The EPM240 and EPM570 devices support two I/O banks, as shown in
Each of these banks support all the LVTTL and LVCMOS standards shown in

The EPM1270 and EPM2210 devices support four I/O banks, as shown in
Each of these banks support all of the LVTTL and LVCMOS standards shown in

clamping diode on inputs and PCI drive compliance on outputs. You must use Bank 3
for designs requiring PCI compliant I/O pins. The Quartus II software automatically
places I/O pins in this bank if assigned with the PCI I/O standard.
