I/O Banks
Cyclone IV Device Handbook, Volume 1
I/O pins on Cyclone IV devices are grouped together into I/O banks. Each bank has a
separate power bus.
Cyclone IV E devices have eight I/O banks, as shown in
pin is associated with one I/O bank. All single-ended I/O standards are supported in
all banks except HSTL-12 Class II, which is only supported in column I/O banks. All
differential I/O standards are supported in all banks. The only exception is HSTL-12
Class II, which is only supported in column I/O banks.
Cyclone IV GX devices have up to ten I/O banks and two configuration banks, as
shown in
configuration I/O bank contains three user I/O pins that can be used as normal user
I/O pins if they are not used in configuration modes. Each device I/O pin is
associated with one I/O bank. All single-ended I/O standards are supported except
HSTL-12 Class II, which is only supported in column I/O banks. All differential I/O
standards are supported in top, bottom, and right I/O banks. The only exception is
HSTL-12 Class II, which is only supported in column I/O banks.
The entire left side of the Cyclone IV GX devices contain dedicated high-speed
transceiver blocks for high speed serial interface applications. There are a total of 2, 4,
and 8 transceiver channels for Cyclone IV GX devices, depending on the density and
package of the device. For more information about the transceiver channels
supported, refer to
