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
from 40K to 8M system gates.
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.
