Notes to
(1) User I/O pins are used as inputs or outputs; clock input pins are used as inputs only; clock output pins are used as output only.
(2) Bank 9 does not have VREF pin. If input pins with VREF I/O standards are used in bank 9 during user mode, it shares the VREF pin in bank 8.

Each Cyclone IV I/O bank has its own VCCIO pins. Each I/O bank can support only
one V
single-ended or differential standards can be simultaneously supported in a single
I/O bank, as long as they use the same V
When designing LVTTL/LVCMOS inputs with Cyclone IV devices, refer to the
following guidelines:

Voltage-referenced standards are supported in an I/O bank using any number of
single-ended or differential standards, as long as they use the same V
values. For example, if you choose to implement both SSTL-2 and SSTL-18 in your
Cyclone IV devices, I/O pins using these standards—because they require different

When using Cyclone IV devices as a receiver in 3.3-, 3.0-, or 2.5-V LVTTL/LVCMOS
systems, you are responsible for managing overshoot or undershoot to stay in the
absolute maximum ratings and the recommended operating conditions, provided in
