XA3SD1800A-4CSG484Q xilinx




XA devices are available in both extended-temperature Q-Grade (–40°C to +125°C TJ) and I-Grade (–40°C to +100°C TJ) and are qualified to the industry recognized AEC-Q100 standard.


The XA Spartan-3A DSP family builds on the success of the earlier XA Spartan-3E and XA Spartan-3 FPGA families by adding hardened DSP MACs with pre-adders, significantly increasing the throughput and performance of this low-cost family. These XA Spartan-3A DSP 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, XA Spartan-3A DSP FPGAs are ideally suited to a wide range of automotive electronics applications, including infotainment, driver information, and driver assistance modules.


The XA Spartan-3A DSP family is a superior alternative to mask programmed ASICs. FPGAs avoid the high initial mask set costs and lengthy development cycles, while also permitting design upgrades in the field with no hardware replacement necessary because of its inherent programmability, an impossibility with conventional ASICs and ASSPs with their inflexible architecture.
