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.

is a graphic representation only. Refer to the pin list and the Quartus II software for exact pin locations.
Each I/O bank has its own
VCCIO
pins. A single device can support 1.5-V,
1.8-V, 2.5-V, and 3.3-V interfaces; each individual bank can support a
different standard with different I/O voltages. Each bank also has dual-
purpose
VREF
pins to support any one of the voltage-referenced
standards (e.g., SSTL-3) independently. If an I/O bank does not use
voltage-referenced standards, the V
REF
pins are available as user I/O pins.
