Spartan-3E FPGA Family: Pinout Descriptions
Package Overview
Table 125 shows the eight low-cost, space-saving
production package styles for the Spartan-3E family. Each
package style is available as a standard and an
environmentally friendly lead-free (Pb-free) option. The
Pb-free packages include an extra ‘G’ in the package style
name. For example, the standard “VQ100” package
becomes “VQG100” when ordered as the Pb-free option.
The mechanical dimensions of the standard and Pb-free
packages are similar. Package drawings and package
material declaration data sheets (MDDS) are available on
www.xilinx.com.
Not all Spartan-3E densities are available in all packages.
For a specific package, however, there is a common
footprint that supports all the devices available in that
package. See the footprint diagrams that follow.
For additional package information, see UG112: Device
Package User Guide.

packages are superior in almost every other aspect, as
summarized in Table 126. Consequently, Xilinx
recommends using BGA packaging whenever possible.
Selecting the Right Package Option
Spartan-3E FPGAs are available in both quad-flat pack
(QFP) and ball grid array (BGA) packaging options. While
QFP packaging offers the lowest absolute cost, the BGA
