Each package style is available in 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 “CS484” package becomes “CSG484” when
ordered as the Pb-free option. The mechanical dimensions
of the standard and Pb-free packages are similar, as shown
in the mechanical drawings provided in Table 61.
For additional package information, see UG112: Device
Package User Guide.
Mechanical Drawings
Detailed mechanical drawings for each package type are
available from the Xilinx web site at the specified location in
