Overview

The Spartan®-3A family of Field-Programmable Gate Arrays (FPGAs) solves the design challenges in most high-volume, cost-sensitive, I/O-intensive electronic applications. The five-member family offers densities ranging from 50,000 to 1.4 million system gates, as shown in Table 1. The Spartan-3A FPGAs are part of the Extended Spartan-3A family, which also include the non-volatile Spartan-3AN and the higher density Spartan-3A DSP FPGAs. The Spartan-3A family builds on the success of the earlier Spartan-3E and Spartan-3 FPGA families. New features improve system performance and reduce the cost of configuration. These Spartan-3A family enhancements, combined with proven 90 nm process technology, deliver more functionality and bandwidth per dollar than ever before, setting the new standard in the programmable logic industry. Because of their exceptionally low cost, Spartan-3A FPGAs are ideally suited to a wide range of consumer electronics applications, including broadband access, home networking, display/projection, and digital television equipment. The Spartan-3A family is a superior alternative to mask programmed ASICs. FPGAs avoid the high initial cost, lengthy development cycles, and the inherent inflexibility of conventional ASICs, and permit field design upgrades.
