AMD XCKU025-1FFVA1156I

Overview

XCKU025-1FFVA1156I from AMD is a Kintex UltraScale FPGA featuring 640K logic cells, 28.8 Gb/s transceiver line rate, and 1156-pin Flip-Chip Fine-Pitch Ball Grid Array (FC-FBGA) packaging. It integrates hardened PCIe Gen3 x8, DDR4 memory controller, and 1920 DSP slices for high-throughput data processing in reconfigurable acceleration platforms.

For engineers reviewing the XCKU025-1FFVA1156I datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver compliance (PCIe Gen3/SGMII), I/O voltage support (1.2V–1.8V), thermal design power (22W typical), and configuration interface (JTAG/SelectMAP).

Technical Context

The XCKU025-1FFVA1156I implements a heterogeneous architecture with programmable logic fabric, UltraScale+ transceivers supporting 28.8 Gb/s PAM4 and NRZ modes, and integrated hard IP blocks including PCIe Gen3 x8 root port and endpoint, 10G Ethernet MAC, and AXI-4 interconnect. It supports multi-voltage I/O banks with independent VCCO and VREF per bank.

Configuration is performed via Master SPI or JTAG, with bitstream encryption using AES-256 and HMAC-SHA-256 authentication. The device operates across industrial temperature range (–40°C to +100°C junction) and supports partial reconfiguration for dynamic function swapping without system reset.

FAQ

What is the maximum supported DDR4 data rate for XCKU025-1FFVA1156I?

The XCKU025-1FFVA1156I supports DDR4-2400 (1200 MHz clock) across a 64-bit interface, delivering up to 19.2 GB/s peak bandwidth. This capability is implemented via dedicated hard memory controller IP and validated for industrial temperature operation with JEDEC-compliant timing parameters.

Does XCKU025-1FFVA1156I support PCIe Gen4?

The XCKU025-1FFVA1156I includes hardened PCIe Gen3 x8 endpoints and root ports. While its GTY transceivers operate up to 28.8 Gb/s, PCIe Gen4 compliance requires Gen4-specific PHY logic and protocol stack not integrated in this device; Gen4 implementation would require soft IP and significant resource overhead.

What configuration modes are supported by XCKU025-1FFVA1156I?

XCKU025-1FFVA1156I supports Master SPI, Slave Serial, Slave SelectMAP, and JTAG configuration modes. Master SPI is commonly used for fast, single-image boot; JTAG enables debugging and programming during development and field updates with AES-256 encrypted bitstream support.

Is partial reconfiguration supported on XCKU025-1FFVA1156I?

Yes, XCKU025-1FFVA1156I fully supports partial reconfiguration through Vivado Design Suite tools. This allows dynamic swapping of logical partitions-such as switching between different filter kernels or protocol engines-without resetting the entire device or disrupting active I/O channels.

What is the operating temperature range for XCKU025-1FFVA1156I?

XCKU025-1FFVA1156I is rated for industrial temperature operation with a junction temperature range of –40°C to +100°C. This specification applies to the I-grade device variant and is verified under worst-case voltage and process corners per AMD's Kintex UltraScale DC and AC characteristics documentation.
