XCKU5P-1FFVB676E - 280-I/O Kintex UltraScale+ FPGA | AMD
The AMD Xilinx XCKU5P-1FFVB676E is a Kintex UltraScale+ field-programmable gate array built on FinFET process technology, with 474,600 logic cells, 280 I/O, 17,280 Kb of block RAM, and 1,824 DSP slices in a 676-pin FCBGA package measuring 27 x 27 mm. The -1 suffix identifies its speed grade, while the E suffix identifies the extended-temperature option. Its operating range is specified from 0°C to 100°C at the junction.
A Kintex UltraScale+ FPGA is a programmable semiconductor used to implement digital control, data processing, signal processing, networking, and embedded systems. Within the FPGA hierarchy, it combines configurable logic blocks, block RAM, DSP resources, programmable I/O, dedicated clocking, and high-speed serial transceivers. This balance makes the device useful when designers need substantial parallel processing resources while retaining the flexibility of reconfigurable hardware.
The XCKU5P-1FFVB676E provides 474,600 logic cells for control logic and complex digital pipelines, together with 1,824 DSP slices for filtering, modulation, correlation, fixed-point arithmetic, and other multiply-accumulate-intensive tasks. Its 17,280 Kb of block RAM provides on-chip storage for packet buffers, waveform data, lookup tables, and data-plane staging. The 280 I/O expand board connectivity without relying primarily on external serial links.
The Kintex UltraScale+ architecture uses a FinFET implementation to combine high logic density with performance and power efficiency. Its device-specific configuration, bitstream, package pinout, and power characteristics must be handled as one design target rather than as interchangeable generic FPGA parameters. UltraScale+ package pinout resources and AMD product documentation should be used to verify each ball assignment, differential-pair polarity, supply requirement, and configuration connection before schematic or PCB signoff.
Typical uses include industrial machine vision, high-throughput data acquisition, digital communications, radar and signal-processing front ends, network infrastructure, test equipment, and high-speed protocol bridges. The combination of DSP slices and block RAM makes the device suitable when algorithm behavior or system requirements may evolve faster than a fixed ASIC design cycle. Its 280 I/O also supports parallel sensors, converters, memory interfaces, and board-level control signals.
Design planning should account for the 676-ball FCBGA footprint, multilayer PCB construction, controlled-impedance routing, separate power distribution, decoupling, thermal management, and configuration-signal handling. Differential and high-speed interfaces require trace-length matching and reference-plane continuity, while the 27 x 27 mm package demands careful escape routing from its dense ball array. Prototype platforms can reduce hardware risk before a production board is committed.
This page combines the verified device identity, package and resource details with practical application guidance, same-package migration options, and engineering-focused design notes. The comparisons emphasize how speed grade, temperature grade, resource capacity, package, and qualification requirements affect replacement decisions rather than treating every Kintex UltraScale+ FPGA as interchangeable.
