AMD XCKU040-2FBVA676I

Overview

XCKU040-2FBVA676I from AMD (formerly Xilinx) is a Kintex UltraScale FPGA featuring 443,200 logic cells, 2,520 DSP slices, and 28.4 Mb of block RAM. It supports up to 48 GTY transceivers operating at 32.75 Gb/s, and is packaged in a 676-pin FCBGA with 0.8 mm pitch. It targets high-bandwidth data processing in 5G wireless infrastructure equipment.

For engineers reviewing the XCKU040-2FBVA676I datasheet, pinout, applications, or equivalent options, key selection factors include transceiver lane count and speed, logic density, I/O voltage support (1.2 V to 1.8 V), thermal design power (29.5 W typical), and industrial temperature grade (-40°C to +100°C).

Technical Context

The XCKU040-2FBVA676I implements a heterogeneous architecture with programmable logic fabric, hardened IP blocks (PCIe Gen3 x16, 10/25/100G Ethernet MACs), and multi-rate GTY transceivers. It uses 20 nm bulk CMOS process technology and supports partial reconfiguration.

It delivers deterministic low-latency signal processing via dedicated routing for clock and reset networks, and integrates UltraScale+ SelectIO technology supporting SSTL, HSTL, LVCMOS, and differential standards including LVDS and MIPI D-PHY.

FAQ

What is the maximum supported transceiver data rate for the XCKU040-2FBVA676I?

The XCKU040-2FBVA676I supports GTY transceivers with a maximum data rate of 32.75 Gb/s per lane. This rate is validated for protocols including 100G Ethernet (4×25G), CEI-28G, and CPRI Option 10. The XCKU040-2FBVA676I achieves this using adaptive equalization and low-jitter clocking architecture, and requires proper PCB stackup and controlled impedance routing to maintain signal integrity.

Does the XCKU040-2FBVA676I support partial reconfiguration?

Yes, the XCKU040-2FBVA676I fully supports partial reconfiguration through Vivado Design Suite. This capability allows runtime updates of specific logic regions without disrupting active functions such as PCIe links or transceiver operations. The XCKU040-2FBVA676I implements frame-based reconfiguration with secure bitstream authentication, enabling field-upgradable features in deployed 5G baseband units.

What I/O standards are supported by the XCKU040-2FBVA676I?

The XCKU040-2FBVA676I supports SSTL, HSTL, LVCMOS, LVDS, and MIPI D-PHY across its 400+ user I/O pins. Each of the 24 I/O banks can be independently configured for 1.2 V to 1.8 V VCCO, enabling mixed-standard interfaces-for example, DDR4 memory (SSTL12) alongside MIPI camera sensors (D-PHY) on the same device. The XCKU040-2FBVA676I does not support RSDS or BLVDS.

Is the XCKU040-2FBVA676I qualified for industrial temperature operation?

Yes, the XCKU040-2FBVA676I is rated for industrial temperature range: –40°C to +100°C case temperature. It is tested per JEDEC JESD22-A104 and JESD22-A108 reliability standards, with burn-in and HTOL qualification. This makes the XCKU040-2FBVA676I suitable for outdoor 5G radio units and avionics edge nodes where ambient thermal cycling exceeds commercial-grade limits.

What hardened IP blocks are integrated into the XCKU040-2FBVA676I?

The XCKU040-2FBVA676I integrates hardened PCIe Gen3 x16, 10/25/100G Ethernet MACs, and 100G Interlaken controllers. These blocks operate at full line rate with deterministic latency and zero fabric resource consumption. The XCKU040-2FBVA676I also includes clock management tiles (CMTs) with MMCM and PLL, and system monitor for on-die temperature and voltage sensing-no external monitoring IC required.
