General Description
The Extended Spartan®-3A family of Field-Programmable Gate Arrays (FPGAs) solves the design challenges in many high-
volume, cost-sensitive electronic applications. With 12 devices ranging from 50,000 to 3.4 million system gates (as shown in
Table 1 ), the Extended Spartan-3A family provides a broad range of densities and package options, integrated DSP MACs,
and low total system cost while increasing functionality. The Extended Spartan-3A family includes the Spartan-3A devices
and the higher density Spartan-3A DSP devices. It also includes the nonvolatile Spartan-3AN devices, which combine
leading-edge FPGA and flash technologies to provide a new evolution in security, protection and functionality, ideal for
space-critical or secure applications.
The Extended Spartan-3A family improves system performance and reduces the cost of configuration. These
enhancements, combined with proven 90 nm process technology, deliver more functionality and bandwidth per dollar.
Because of its exceptionally low cost, the Extended Spartan-3A family is ideally suited to a wide range of consumer
electronics applications, including broadband access, home networking, display/projection, and digital television equipment.
The Extended Spartan-3A family is a superior alternative to mask-programmed ASICs. FPGAs avoid the high initial cost,
lengthy development cycles, the inherent inflexibility of conventional ASICs, and permit field design upgrades.
