Product Descriptions

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. ​
