XC3SD1800A-4CSG484I

Product Summary

The XC3SD1800A-4CSG484I is a member of Spartan-3A DSP family of Field-Programmable Gate Arrays (FPGAs), which solves the design challenges in most high- volume, cost-sensitive, high-performance DSP applications. The XC3SD1800A-4CSG484I offers densities ranging from 1.8 to 3.4 million system gates.The XC3SD1800A-4CSG484I builds on the success of the Spartan-3A FPGA family by increasing the amount of memory per logic and adding XtremeDSP DSP48A slices.The Spartan-3A DSP FPGAs extend and enhance the Spartan-3A FPGA family. The XC3SD1800A-4CSG484I is tailored for DSP applications and have additional block RAM and XtremeDSP DSP48A slices.The Spartan-3A DSP 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. Also, FPGA programmability permits design upgrades in the field with no hardware replacement necessary, an impossibility with ASICs.
