For more information on Device Packaging Specifications, refer to the support section of the Altera website.
(http://www.altera.com/support/devices/packaging/specifications/pkg-pin/spe-index.html).
The numbers are the maximum I/O counts (including clock input pins) supported by the device-package
combination and can be affected by the configuration scheme selected for the device.
All the packages available in lead-free and leaded options.
The EP3C40 device in the F780 package supports restricted vertical migration. Maximum user I/O is restricted to
510 I/Os if you enable migration to the EP3C120 and are using voltage referenced I/O standards. If you are not
using voltage referenced I/O standards the maximum number of I/Os can be increased.
The E144 package has an exposed pad at the bottom of the package. This exposed pad is a ground pad that must
be connected to the ground plane on your PCB. This exposed pad is used for electrical connectivity and not for
thermal purposes.
All the UBGA packages will be supported starting in Quartus II v7.1 SP1 except for the UBGA packages of EP3C16
which will be supported starting in Quartus II v7.2
