Spartan-II FPGAs are a cost-optimized Virtex
architecture designed in an 0.18u/0.22u, 6LM process, while Virtex FPGAs
are currently in the 0.22u, 6LM process. In the first half of 2000, Virtex
FPGAs will also be available in the 0.18u/0.22, 6LM process. From a price
standpoint, the Spartan-II family will feature more aggressive pricing than
the Virtex family. From a feature standpoint, Spartan-II FPGAs are the same
as Virtex FPGAs with the exception of the low power features. Spartan-II
FPGAs have replaced the two temperature diode pins found on Virtex FPGAs
with two pins for low power (powerdown and powerdown status). The Spartan-II
family will be available in only the most popular and lowest cost package
parts, which results in lower prices to our customers and will share only
two common packages with the Virtex family, which are the FG256 and FG456
packages |
