Performance Highlights: Why Choose the XCKU040-2FFVA1156I?
Best-in-Class Price/Performance/Watt at 20nm
<invoke name=”web_fetch”> The Kintex UltraScale family is engineered to deliver the **best price/performance/watt ratio** in the mid-range FPGA segment at 20nm. Compared to previous-generation Kintex-7 devices, the UltraScale architecture provides up to **40% lower dynamic power consumption** while simultaneously offering significantly higher logic density and transceiver throughput.
ASIC-Class Architecture for High-Utilization Designs
The UltraScale architecture introduces ASIC-like clocking with fine-granular clock gating, next-generation routing resources, and 3D-on-3D IC integration. This translates to consistent timing closure even at high utilization rates — a common pain point in competitive FPGA families.
