Are packages between the different 7 series devices pin compatible?
What packages are pin compatible within any given 7 series family?
Artix-7 devices are only pin compatible with other Artix-7 devices in the same package.
Kintex-7 devices are pin compatible with other Kintex-7 devices in the same package.
In addition, FB and FF packages of the same pin-count designator are pin compatible with a few notes.
It should be noted that the FB and FF have substantially different decoupling capacitor recommendations.
Also, note that FB packages do not utilize Vccaux_IO pins.
In the FF packages, the vccaux_io_g must be connected in order to drive the pre-driver for the HP I/Os.
Therefore, if you are planning on migrating to the FF, you must connect vccaux_io to the appropriate voltage/regulator solution for your final design.
Note: There are vccaux_io pins for FB packages, but that does not mean that any I/Os take advantage of this supply.
These pins are place-holders for pin compatibility with FF packages.
Virtex-7 devices are pin compatible with other Virtex-7 devices in the same package.
In addition FF, FH, and FL packages of the same pin-count designator are pin compatible with a note.
FH packages have a larger lid than the FF or FL.
