Package
Stratix II devices support enhanced PLLs and fast PLLs. HardCopy II
devices also support enhanced PLLs and fast PLLs, but with two
variations:

supports. The Stratix II reference columns are divided based on package,
not density.
Stratix II devices support 6 or 12 PLLs depending on the package offering,
and not the device density. The HardCopy II PLLs are not removed
symmetrically from all four sides. In general, fast PLLs are removed from
sides that do not support high speed IOEs since the primary use of the fast
PLL on the sides is for high speed I/O interface functions.

Table 8–17. HardCopy II Embedded Memory Features (Part 2 of 2)
HardCopy II devices have a different number of PLLs than Stratix II
devices.
HardCopy II devices may support fewer I/O standards for clock
inputs and outputs. This is explained in the I/O standards support
section later in this chapter.
Stratix II M4K blocks support .mif file loading.
Stratix II memory blocks remain powered up even when not used.
