Mechanical Drawings
Detailed mechanical drawings for each package type are
available from the Xilinx® web site at the specified location
in
Table 127: Xilinx Package Mechanical Drawings and Material Declaration Data Sheets
Package Pins by Type
Each package has three separate voltage supply
inputs—VCCINT, VCCAUX, and VCCO—and a common
ground return, GND. The numbers of pins dedicated to
these functions vary by package, as shown in

A majority of package pins are user-defined I/O or input
pins. However, the numbers and characteristics of these I/O
depend on the device type and the package in which it is
available, as shown in
imum number of single-ended I/O pins available, assuming
that all I/O-, INPUT-, DUAL-, VREF-, and CLK-type pins are
used as general-purpose I/O. Likewise, the table shows the
maximum number of differential pin-pairs available on the
package. Finally, the table shows how the total maximum
user-I/Os are distributed by pin type, including the number
of unconnected—i.e., N.C.—pins on the device.
