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

®

II software I/O pin counts include four additional pins,

TDI, TDO, TMS,

and

TCK,

which are not

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

Automotive-Grade

Device Handbook.

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

Table 1–3.
