This parameter includes global clock pins.
TQFP: thin quad flat pack.
PQFP: plastic quad flat pack.
Cyclone devices support vertical migration within the same package (i.e., designers can migrate between the
EP1C3 device in the 144-pin TQFP package and the EP1C6 device in the same package).

Vertical migration means you can migrate a design from one device to
another that has the same dedicated pins, JTAG pins, and power pins, and
are subsets or supersets for a given package across device densities. The
largest density in any package has the highest number of power pins; you
must use the layout for the largest planned density in a package to
provide the necessary power pins for migration.
For I/O pin migration across densities, cross-reference the available I/O
pins using the device pin-outs for all planned densities of a given package
type to identify which I/O pins can be migrated. The Quartus
software can automatically cross-reference and place all pins for you
when given a device migration list. If one device has power or ground
pins, but these same pins are user I/O on a different device that is in the
migration path,the Quartus II software ensures the pins are not used as
user I/O in the Quartus II software. Ensure that these pins are connected
