AMD XCV400E-7BG432C0773

Overview

XCV400E-7BG432C from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array with 569,952 system gates, 10,800 logic cells, and 40 block RAMs totaling 163,840 bits. It features eight digital Delay-Locked Loops (DLLs), supports LVDS/BLVDS/LVPECL differential I/O up to 622 Mb/s, and targets high-speed communication and signal processing applications.

For engineers reviewing the XCV400E-7BG432C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL timing behavior, block RAM configuration modes, and migration guidance from Virtex-E to later families.

Technical Context

The XCV400E-7BG432C implements a regular array of Configurable Logic Blocks (CLBs) - each containing four 4-input LUTs, dedicated carry chains, and dual flip-flops per slice - surrounded by programmable Input/Output Blocks (IOBs) with SelectI/O+ support. Its 40×60 CLB array enables complex synchronous logic with register-to-register delays as low as 4.3 ns at speed grade -7.

I/O functionality is organized into eight banks, each requiring shared VCCO for output standards and optional VREF for input thresholds. The device integrates 40 × 4096-bit true dual-port block RAMs and 153,600 bits of distributed RAM, with clock management handled by eight fully digital DLLs supporting zero-delay LVPECL/LVDS clock conversion and DDR duty-cycle correction.

Manufacturer

Xilinx, now part of AMD, is a pioneer in programmable logic technology, delivering FPGA, SoC, and adaptive compute acceleration platforms since 1984.

The Virtex-E family was designed for high-performance, low-power reconfigurable computing in communications infrastructure, test equipment, and military/aerospace systems where 1.8 V core operation and advanced I/O flexibility were critical.

FAQ

What is the maximum differential I/O bandwidth supported by XCV400E-7BG432C?

XCV400E-7BG432C supports up to 183 differential I/O pairs, enabling aggregate differential bandwidth exceeding 100 Gb/s when operating LVDS at 622 Mb/s per pair. This bandwidth assumes full utilization of all differential pins with proper PCB routing, termination, and DLL-synchronized capture clocks as specified in DS022-1 Module 3.

Does XCV400E-7BG432C support true dual-port block RAM operation?

Yes, XCV400E-7BG432C includes 40 block RAMs, each configured as a true dual-port 4096-bit memory with independent address, write enable, and clock signals per port. This allows simultaneous read and write operations at different addresses - essential for ping-pong buffering and FIFO implementations without external memory.

Can XCV400E-7BG432C be used in place of earlier Virtex devices?

XCV400E-7BG432C is not bitstream-compatible with original Virtex FPGAs, but designs can be recompiled into XCV400E-7BG432C using Xilinx Foundation or Alliance tools. Pin compatibility exists with some exceptions - verify I/O banking rules and DLL pin assignments against DS022-4 pinout tables before migration.

What are the VCCO voltage requirements for LVCMOS18 I/O on XCV400E-7BG432C?

For LVCMOS18 operation, XCV400E-7BG432C requires VCCO = 1.8 V on the corresponding I/O bank. Unlike earlier Virtex families, input buffers for LVCMOS18 are powered by VCCO (not VCCINT), so mixing LVCMOS18 with LVTTL in the same bank is prohibited unless both use identical VCCO.

Is XCV400E-7BG432C still in active production?

No - XCV400E-7BG432C was discontinued per Xilinx Notices XCN09001 and XCN12026. Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for obsolescence mitigation, including migration paths to Spartan-6 or Artix-7 families where functionally appropriate.
