Chapter 6: I/O Features in Cyclone IV Devices 6–21
I/O Banks
March 2016 Altera Corporation Cyclone IV Device Handbook,
Volume 1
Each Cyclone IV I/O bank has its own
VCCIO
pins. Each I/O bank can support only one V
CCIO
setting from among 1.2, 1.5, 1.8,
2.5, 3.0, or 3.3 V. Any number of supported single-ended or differential standards can be simultaneously supported in a single
I/O bank, as long as they use the same V
CCIO
levels for input and output pins.

Note to Table 6–4:
(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.

Notes to Table 6–5:
(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.
