Table 1–2. Cyclone II Package Options & Maximum User I/O Pins
Cyclone II devices support vertical migration within the same package (for example, you can migrate between the
EP2C20 device in the 484-pin FineLine BGA package and the EP2C35 and EP2C50 devices in the same package).
The Quartus
available as general purpose I/O pins.
TQFP: thin quad flat pack.
PQFP: plastic quad flat pack.
Vertical migration is supported between the EP2C5F256 and the EP2C8F256 devices. However, not all of the DQ
and DQS groups are supported. Vertical migration between the EP2C5 and the EP2C15 in the F256 package is not
supported.
The I/O pin counts for the EP2C5, EP2C8, and EP2C15A devices include 8 dedicated clock pins that can be used
for data inputs. The I/O counts for the EP2C20, EP2C35, EP2C50, and EP2C70 devices include 16 dedicated clock
pins that can be used for data inputs.
EP2C8A, EP2C15A, and EP2C20A have a Fast On feature that has a faster POR time. The EP2C15A is only available
with the Fast On option.
The EP2C5 optionally support the Fast On feature, which is designated with an “A” in the device ordering code.
The EP2C5A is only available in the automotive speed grade. Refer to the Cyclone II section in the

Cyclone II devices support vertical migration within the same package
(for example, you can migrate between the EP2C35, EPC50, and EP2C70
devices in the 672-pin FineLine BGA package). The exception to vertical
migration support within the Cyclone II family is noted in
