AMD XCV1000E-6FG680C

Overview

XCV1000E-6FG680C from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array (FPGA) with 1,569,178 system gates and 27,648 logic cells in a 64 × 96 CLB array. It features eight digital Delay-Locked Loops (DLLs), up to 660 user I/O pins in FG680 package, and supports LVDS (622 Mb/s), LVPECL, and PCI 3.3 V/66 MHz interfaces - deployed in high-speed communications infrastructure and test equipment.

For engineers reviewing the XCV1000E-6FG680C datasheet, pinout, applications, or equivalent options, key selection criteria include its -6 speed grade (130 MHz internal performance), 1.8 V core voltage with 3.3 V I/O tolerance, dual-port block RAM capacity (393,216 bits), and fine-pitch BGA packaging for dense PCB layouts.

Technical Context

The XCV1000E-6FG680C implements a flexible, regular FPGA architecture with configurable logic blocks (CLBs) surrounded by programmable input/output blocks (IOBs), interconnected via a hierarchical routing matrix. Its eight fully digital DLLs provide clock multiply/divide, zero-delay LVPECL/LVDS-to-I/O conversion, and 50% duty cycle synthesis for DDR applications.

It integrates 96 block SelectRAM modules (each 4096-bit true dual-port RAM), delivering up to 1.66 Tb/s memory bandwidth, alongside distributed RAM (393,216 bits) and dedicated carry logic for arithmetic acceleration. I/O banking enforces VCCO/VREF grouping across eight banks, supporting mixed standards like LVTTL, SSTL3, HSTL IV, and LVDS within compatible voltage domains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA-based system integration applications.

Compared with XCV1000E-6FG680C, the -7 variant trades speed for lower static power and relaxed timing closure, while the FG676 variant maintains identical functionality in a smaller package at the expense of 4 I/O pins - both require no HDL or constraint file changes but demand package-specific PCB redesign.

Manufacturer

Xilinx, now part of AMD, is a pioneer in programmable logic technology, specializing in FPGAs, adaptive SoCs, and software-defined solutions for aerospace, defense, and high-performance computing.

The Virtex-E family was designed for high-bandwidth, low-latency system integration - targeting applications demanding both logic density and I/O flexibility, such as protocol bridging, signal processing, and real-time control.

FAQ

What is the maximum differential I/O pair count supported by XCV1000E-6FG680C?

XCV1000E-6FG680C supports up to 344 differential I/O pairs, as confirmed in DS022-1 Table 1. This enables implementation of 344 LVDS channels (688 pins total) for ultra-high-bandwidth data acquisition or parallel interface expansion, subject to I/O banking constraints and PCB routing capability.

Does XCV1000E-6FG680C support 5 V tolerant I/O?

No, XCV1000E-6FG680C does not support native 5 V tolerant I/O. Its I/O pins are 3 V tolerant, and can be made 5 V tolerant only with an external 100 Ω series resistor per pin - a method validated in DS022-1 Section "Virtex-E Compared to Virtex Devices" but not recommended for high-speed or hot-swap applications.

How many DLLs are integrated into XCV1000E-6FG680C, and what clock frequencies do they support?

XCV1000E-6FG680C integrates eight fully digital Delay-Locked Loops (DLLs), each capable of clock multiplication up to 4× and supporting LVPECL/LVDS clock inputs exceeding 300 MHz. These DLLs provide zero-delay conversion to any I/O standard and generate 50% duty cycle clocks essential for DDR interfaces.

Is XCV1000E-6FG680C pin-compatible with earlier Virtex family devices?

XCV1000E-6FG680C is not pin-compatible with original Virtex devices. While some packages share ball counts (e.g., FG680), banking rules, VCCO/VREF pin assignments, and I/O buffer power domains differ significantly - DS022-1 explicitly states "The Virtex-E family is not bitstream-compatible with the Virtex family" and cites minor exceptions in pinout.

What is the block RAM configuration of XCV1000E-6FG680C, and how is it structured?

XCV1000E-6FG680C contains 96 block SelectRAM modules totaling 393,216 bits, organized as 4096-bit true dual-port RAMs. Each block supports independent read/write widths per port (e.g., 32-bit write / 64-bit read), enabling efficient bus-width conversion and simultaneous access in applications like video line buffers or packet classification tables.
