Spartan-3 FPGA Family:
Introduction and Ordering
Information
0 0 Advance Product Specification
Introduction
The Spartan™-3 family of Field-Programmable Gate Arrays
is specifically designed to meet the needs of high volume,
cost-sensitive consumer electronic applications. The
eight-member family offers densities ranging from 50,000 to
five million system gates, as shown in Table 1.
The Spartan-3 family builds on the success of the earlier
Spartan-IIE family by increasing the amount of logic
resources, the capacity of internal RAM, the total number of
I/Os, and the overall level of performance as well as by
improving clock management functions. Numerous
enhancements derive from state-of-the-art Virtex™-II tech-
nology. These Spartan-3 enhancements, combined with
advanced process technology, deliver more functionality
and bandwidth per dollar than was previously possible, set-
ting new standards in the programmable logic industry.
Because of their exceptionally low cost, Spartan-3 FPGAs
are ideally suited to a wide range of consumer electronics
applications, including broadband access, home network-
ing, display/projection and digital television equipment.
The Spartan-3 family is a superior alternative to mask pro-
grammed ASICs. FPGAs avoid the high initial cost, the
lengthy development cycles, and the inherent inflexibility of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary, an impossibility with ASICs.
