The Xilinx XCKU040-2FFVA1156E is a high-performance FPGA from the Kintex UltraScale family, delivering ASIC-class system-level performance at the right balance of price, performance, and power. Built on 20 nm CMOS technology and operating at a core voltage of 0.95 V, this device features 530,250 logic cells and a maximum clock speed of 725 MHz, making it suitable for the most demanding communications, data center, and signal processing applications.

Architecture

The XCKU040-2FFVA1156E features 530,250 logic cells organised into 30,300 configurable logic blocks (CLBs), providing massive logic capacity for complex system designs. The device incorporates 21.6 Mb of block RAM, enabling large on-chip data storage for high-bandwidth applications. The Kintex UltraScale family leverages second-generation 3D IC technology, delivering up to 1.5M system logic cells in the highest-density members, with the XCKU040 representing a mid-range option in the family.

High-Speed Connectivity

The device provides 520 user I/O pins, supporting a wide range of high-speed serial and parallel interfaces. Integrated transceivers support data rates up to 32 Gb/s, making the device suitable for optical transport networks, PCI Express, and other high-bandwidth applications. The device includes multiple MMCMs (Mixed-Mode Clock Managers) and PLLs for advanced clock management, providing precise frequency synthesis and phase control.

Power and Performance

The Kintex UltraScale family is available in -3, -2, -1, and -1L speed grades, with -3 having the highest performance. The XCKU040-2FFVA1156E features the -2 speed grade, providing an optimal balance of performance and power consumption. The device operates from a 0.95V core supply with a tolerance range of 0.922V to 0.979V. The -1L devices can operate at either 0.95V or 0.90V, with reduced performance and power when operated at the lower voltage. Advanced power management features enable efficient operation across a wide range of application scenarios.
