General Description
The Virtex-II family is a platform FPGA developed for high
performance from low-density to high-density designs that
are based on IP cores and customized modules. The family
delivers complete solutions for telecommunication, wire-
less, networking, video, and DSP applications, including
PCI, LVDS, and DDR interfaces.
The leading-edge 0.15 m / 0.12 m CMOS 8-layer metal
process and the Virtex-II architecture are optimized for high
speed with low power consumption. Combining a wide vari-
ety of flexible features and a large range of densities up to
10 million system gates, the Virtex-II family enhances pro-
grammable logic design capabilities and is a powerful alter-
native to mask-programmed gates arrays. As shown in
Table 1, the Virtex-II family comprises 11 members, ranging
Packaging
Offerings include ball grid array (BGA) packages with
0.80 mm, 1.00 mm, and 1.27 mm pitches. In addition to tra-
ditional wire-bond interconnects, flip-chip interconnect is
used in some of the BGA offerings. The use of flip-chip
interconnect offers more I/Os than is possible in wire-bond
versions of the similar packages. Flip-chip construction
offers the combination of high pin count with high thermal
capacity.
Wire-bond packages CS, FG, and BG are optionally avail-
abe in Pb-free versions CSG, FGG, and BGG. See
Virtex-IITable 2 shows the maximum number of user I/Os available.
The Virtex-II device/package combination table
(Table 6 at
the end of this section) details the maximum number of I/Os
for each device and package using wire-bond or flip-chip
technology.
