MAX II Architecture
I/O Standards and Banks
MAX II device IOEs support the following I/O standards:
■

■
■
■
3.3-V LVTTL/LVCMOS
2.5-V LVTTL/LVCMOS
1.8-V LVTTL/LVCMOS
1.5-V LVCMOS
3.3-V PCI
Table 2–4 describes the I/O standards supported by MAX II devices.

Note to Table 2–4:
(1) The 3.3-V PCI is supported in Bank 3 of the EPM1270 and EPM2210 devices.
The EPM240 and EPM570 devices support two I/O banks, as shown in
Figure 2–22. Each of these banks support all the LVTTL and LVCMOS
standards shown in Table 2–4. PCI I/O is not supported in these devices
and banks.
