XCV400E-6FG676C

Field Programmable Gate Array Overview

The XCV400E-6FG676C is a Virtex-E Field Programmable Gate Array manufactured by AMD (Xilinx). It features 129,600 logic gates and 10,800 configurable logic blocks (CLBs) within a 40x60 array. The device includes 163,840 bits of Block SelectRAM and 153,600 bits of distributed RAM. It operates at a maximum internal frequency of 130 MHz with four LUT levels and supports up to 404 user I/Os in the FG676 package. The core voltage is 1.8 V, while I/O banks support 3.3 V standards.

Field Programmable Gate Array Feature Summary

• SRAM-based architecture enabling unlimited re-programmability via external SPROM or on-chip configuration modes.
• Sophisticated memory hierarchy featuring True Dual-Port BlockRAM for high-performance interfaces to external memories.
• High-performance clock management circuitry with eight fully digital Delay-Locked Loops (DLLs) for domain control.
• Flexible SelectI/O+ technology supporting multiple interface standards including LVDS, BLVDS, and LVPECL.

Field Programmable Gate Array Applications

• PCI compliant 3.3 V, 32/64-bit, 33/66-MHz bus implementations
• High-speed arithmetic functions utilizing dedicated carry logic
• Interfaces to 200 MHz ZBT SRAMs and 200 Mb/s DDR SDRAMs

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix (-6) against the design timing requirements, as other grades exist for this device family. Confirm that the FG676 Fine Pitch Ball Grid Array package dimensions match the PCB footprint constraints. Ensure the development environment supports the Virtex-E architecture, as bitstreams are not compatible with standard Virtex devices.

Field Programmable Gate Array Selection Notes

Select this component when designs require high-density logic combined with substantial block memory resources. The Virtex-E family offers improved performance over previous generations, specifically regarding I/O speeds and internal clocking capabilities. Consider the 1.8 V core voltage requirements for power budgeting and the availability of 3.3 V tolerant I/Os for system interfacing.

Field Programmable Gate Array Part Context

This part belongs to the Virtex-E 1.8 V FPGA family, which utilizes an advanced 0.18 μm six-layer metal CMOS process. This manufacturing technology enables smaller die sizes, faster switching speeds, and lower power consumption compared to earlier 2.5 V Virtex devices. The family ranges from 58 k to 4 M system gates.

Field Programmable Gate Array Replacement Considerations

The XCV400E-6FG676C is not bitstream-compatible with the original Virtex family. While pin-compatible with some exceptions, designs must be recompiled for Virtex-E. No direct functional substitutes are listed in the provided documentation; migration to larger devices like the XCV600E requires checking VREF and VCCO pin mappings.
