Frequently Asked Questions (FAQ)
Q: What is the difference between XCKU095-1FFVC1517C and XCKU095-2FFVC1517E? The “-1” vs. “-2” designation refers to the speed grade — the -2 variant offers higher maximum operating frequencies and is screened for extended temperature operation (up to 100°C). The -1C is designed for standard commercial environments (0–85°C).
Q: Is the XCKU095-1FFVC1517C RoHS compliant? Yes, this part is manufactured in compliance with RoHS (Restriction of Hazardous Substances) directives.
Q: Does the XCKU095 support HBM or UltraRAM? No. UltraRAM was introduced in the Kintex UltraScale+ generation. The XCKU095 uses standard 36Kb Block RAM tiles for on-chip storage.
Q: What PCIe generation does the XCKU095-1FFVC1517C support? It supports PCIe Gen1, Gen2, and Gen3 with up to x8 lane width, using two dedicated PCIe hard blocks.
Q: Can I migrate designs from an XCKU085 to the XCKU095? Yes, with care. Both devices share the same UltraScale architecture and package families overlap, but pin-compatibility must be verified for the specific package variant in use.
Summary
The XCKU095-1FFVC1517C is a leading-edge mid-range FPGA that delivers high-density logic, extensive DSP resources, and proven GTH transceiver technology in a commercially-rated package. Whether your design requires 100G network processing, real-time DSP, or multi-protocol high-speed serial connectivity, this device offers the capability, ecosystem support, and development tool maturity to accelerate time-to-market.
For engineers evaluating the full range of Kintex UltraScale and other AMD/Xilinx programmable logic options, this part represents an excellent balance of performance density and cost efficiency at 20nm.
