Why Choose the XCKU035-1SFVA784I?

Best Price/Performance/Watt at 20nm

The Kintex UltraScale family was architected specifically to deliver the best price-to-performance ratio at the 20nm process node. Compared to prior-generation Kintex-7 devices, the XCKU035 offers significantly higher DSP bandwidth, more block RAM, and next-generation GTH transceivers — while consuming less power per unit of logic.

High DSP and Block RAM Density

With 1,440 DSP slices and 19,456 Kbits of total block RAM, the XCKU035-1SFVA784I is particularly well-suited for:

• Digital signal processing (DSP) pipelines
• FIR and FFT acceleration
• Machine learning inference at the edge
• Video processing chains

Next-Generation GTH Transceivers

The device’s 16 GTH transceivers support line rates up to 16.3 Gbps, enabling high-throughput interfaces including 10G/100G Ethernet, PCIe Gen3, JESD204B, and Aurora. This makes the XCKU035-1SFVA784I a strong candidate for backplane, SERDES-heavy, and optical transport designs.

Industrial Temperature Reliability

The -I suffix certifies this device for industrial environments, with junction temperatures up to 100°C. This is critical for applications in:

• Telecom and wireless base stations
• Industrial automation and control
• Medical diagnostic equipment
• Aerospace and defense (commercial variant)

UltraScale Architecture Advantages

The UltraScale architecture introduces ASIC-like clocking with fine-grained clock gating, reducing dynamic power consumption by up to 40% compared to the previous generation. The device is also footprint-compatible with Virtex UltraScale devices, providing a clear scalability path for designs that need more resources.
