Table 15. Cyclone I/O Standards
EP1C3 devices do not support PCI.
EP1C3 devices in the 100-pin TQFP package do not support the LVDS I/O standard.
This I/O standard is only available on output clock pins (PLL_OUT pins).

Advanced I/O Standard Support
Cyclone device IOEs support the following I/O standards:
Table 15
Cyclone devices contain four I/O banks, as shown in
1 and 3 support all the I/O standards listed in
4 support all the I/O standards listed in
standard. I/O banks 2 and 4 contain dual-purpose DQS, DQ, and DM pins
to support a DDR SDRAM or FCRAM interface. I/O bank 1 can also
support a DDR SDRAM or FCRAM interface, however, the configuration
input pins in I/O bank 1 must operate at 2.5 V. I/O bank 3 can also
support a DDR SDRAM or FCRAM interface, however, all the JTAG pins
in I/O bank 3 must operate at 2.5 V.
