AMD XC2V1000-4FFG896C

Overview

XC2V1000-4FFG896C from Xilinx is a 1-million-system-gate Virtex-II platform FPGA in an 896-pin flip-chip fine-pitch BGA (FF896) package, operating at commercial temperature range (0°C to +85°C) with -4 speed grade. It integrates 5,120 Configurable Logic Blocks (CLBs), 40 Digital Clock Managers (DCMs), 40 Block SelectRAM™ modules (totaling 432 Kbits), and supports up to 432 user I/Os. It is used in high-speed telecommunication line cards requiring PCI-X 133 MHz interfaces and LVDS-based data acquisition subsystems.

For engineers reviewing the XC2V1000-4FFG896C datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.5 V core supply, dual-port 18-Kb RAM block configuration flexibility, DCM-based clock deskew for synchronous DDR I/O timing, and DCI-enabled on-die termination for HSTL/SSTL/LVDS standards - all critical for deterministic timing closure in packet-processing FPGAs.

Technical Context

The XC2V1000-4FFG896C implements a hierarchical, segmented Active Interconnect routing architecture with 24 long lines per row/column, 120 hex lines, and predictable delay independent of fanout. Its IOBs support true DDR input/output registers with 180° phase-shifted clocks generated by integrated DCMs, enabling source-synchronous interfaces up to 840 Mb/s.

Each CLB contains four slices with dual 4-input LUTs, dual storage elements (DFF/latch), fast carry chains, and horizontal cascade logic. Block SelectRAM resources are configurable from 16K × 1 to 512 × 36 bits in dual-port mode with three read-during-write options, while dedicated 18 × 18 multipliers operate independently or in conjunction with adjacent RAM blocks for DSP filtering.

Key Specifications

Pinout & Package

XC2V1000-4FFG896C uses the FF896 flip-chip fine-pitch BGA package (1.00 mm pitch, 31 mm × 31 mm body), optimized for thermal dissipation and high I/O count via copper pillar interconnect. Pin definitions follow Xilinx DS031 Module 4, with dedicated banks for VCCO, VCCAUX (3.3 V), and configuration pins (CCLK, DONE, PROG_B, etc.).

FAQ

What is the maximum number of user I/O pins supported by XC2V1000-4FFG896C?

XC2V1000-4FFG896C supports 432 user I/O pins in the FF896 flip-chip BGA package, as confirmed in Table 2 and Table 6 of DS031 (v3.5). This exceeds wire-bond alternatives like BG575 (328 I/Os) and enables dense interface consolidation for protocols such as PCI-X and LVDS. The I/O count is fixed per package and unaffected by speed grade or temperature rating.

Does XC2V1000-4FFG896C support on-chip termination for differential I/O standards?

Yes, XC2V1000-4FFG896C supports Digitally Controlled Impedance (DCI) for differential standards including LVDS_25_DCI and LVDSEXT_25_DCI, as specified in Table 3 of DS031-2 (v3.5). This provides split-termination matching without external resistors, improving signal integrity for high-speed links - a capability absent in Spartan-3 or Virtex-E equivalents.

What clock management resources are integrated into XC2V1000-4FFG896C?

XC2V1000-4FFG896C integrates 40 Digital Clock Manager (DCM) modules, each capable of zero-delay deskew, M/D frequency synthesis, and ±1/256-cycle phase adjustment. These DCMs drive up to 16 global clock multiplexer buffers and support DDR clock forwarding - critical for timing-critical interfaces like DDR SDRAM and source-synchronous ADCs.

Can XC2V1000-4FFG896C be configured via JTAG boundary scan?

Yes, XC2V1000-4FFG896C fully supports IEEE 1532 boundary-scan configuration through its JTAG Test Access Port (TAP), enabling in-system programming and verification. The device implements BYPASS, PRELOAD, SAMPLE, IDCODE, USERCODE, EXTEST, INTEST, and HIGHZ instructions - allowing standardized test and reconfiguration without dedicated configuration pins.

What is the core voltage requirement for XC2V1000-4FFG896C?

XC2V1000-4FFG896C requires a 1.5 V ±3% core supply (VCCINT) per DS031 Module 3, with strict noise and decoupling requirements due to its 0.15 µm/0.12 µm process. This differs from Virtex-E (1.8 V) and Spartan-3 (1.2 V), making power delivery design incompatible across families - a key constraint when migrating designs to XC2V1000-4FFG896C.
