AMD XC2V500-5FG256I

Overview

XC2V500-5FG256I from Xilinx is a 500K-system-gate Virtex-II platform FPGA in a 256-pin Fine-Pitch BGA (FG256) package, operating at industrial temperature (–40°C to +100°C), with 264 user I/Os, 3,072 CLB slices, and eight Digital Clock Managers (DCMs). It implements high-speed logic, embedded memory, and DSP functions for telecom, networking, and video systems requiring PCI, LVDS, or DDR interfaces.

For engineers reviewing the XC2V500-5FG256I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O standard support (LVDS, SSTL, HSTL, PCI-X), DCM timing parameters, DCI termination capability, and wire-bond BGA package constraints - all specific to the FG256 footprint and speed grade –5.

Technical Context

The XC2V500-5FG256I integrates 3,072 CLB slices (each with dual 4-LUTs and dual flip-flops), 32 Block SelectRAM™ modules (18 Kb each, configurable as 16K×1 to 512×36), and 96 dedicated 18×18 multipliers. Its routing uses fourth-generation Active Interconnect Technology with 24 long lines per row/column and predictable delay independent of fanout.

It features eight DCMs supporting precise de-skew, frequency synthesis (M/D ratio), and fine-grained phase shifting (1/256 clock period), plus 16 global clock MUX buffers. Digitally Controlled Impedance (DCI) provides on-chip series or split termination for LVDCI, SSTL_DCI, and HSTL_DCI I/O standards without external resistors.

Key Specifications

Pinout & Package

XC2V500-5FG256I uses the FG256 wire-bond Fine-Pitch BGA package (1.00 mm pitch, 17 mm × 17 mm body), with 256 balls arranged in a 16×16 array. The package supports 264 user I/Os (shared across ball positions), 15 dedicated configuration/control pins (CCLK, DONE, M0–M2, PROG_B, etc.), and separate VCCINT, VCCAUX (3.3 V), and VCCO supply domains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA-based logic and interface applications.

Compared with XC2V500-5FG256I, the –4 variant trades performance for cost in timing-margin-rich designs, while the FG456 variant expands I/O and thermal envelope at the expense of footprint compatibility - making the original FG256 industrial-grade part optimal for space-constrained, ruggedized systems.

FAQ

What is the maximum number of user I/Os supported by XC2V500-5FG256I?

XC2V500-5FG256I supports 264 user I/Os, as confirmed in Table 6 of DS031-1 (v3.5). This count applies specifically to the FG256 wire-bond package and excludes 15 dedicated configuration pins (CCLK, DONE, M0–M2, PROG_B, etc.) and VBATT. All 264 I/Os are fully programmable for single-ended or differential signaling standards.

Does XC2V500-5FG256I support LVDS I/O with on-chip termination?

Yes, XC2V500-5FG256I supports LVDS I/O with on-chip termination via its Digitally Controlled Impedance (DCI) feature. Specifically, the LVDS_25_DCI and LVDS_33_DCI standards are listed in Table 3 of DS031-2 (v3.5), enabling split-termination without external resistors when VCCO = 2.5 V or 3.3 V respectively.

How many Digital Clock Managers (DCMs) does XC2V500-5FG256I include?

XC2V500-5FG256I includes eight Digital Clock Managers (DCMs), as stated in Table 1 of DS031-1 (v3.5). Each DCM provides clock de-skew, frequency synthesis, and fine-grained phase shifting - critical for synchronizing multi-domain designs such as PCI-X interfaces or DDR memory controllers.

Is XC2V500-5FG256I compatible with Pb-free assembly processes?

XC2V500-5FG256I is a leaded (SnPb) device. For Pb-free alternatives, Xilinx offers the FGG256 variant (e.g., XC2V500-5FGG256I), which shares identical logic resources, pinout, and electrical behavior but uses Pb-free solder finish and complies with JEDEC J-STD-020 moisture sensitivity level 3 requirements.

What configuration modes are supported by XC2V500-5FG256I?

XC2V500-5FG256I supports five configuration modes: slave-serial, master-serial, slave SelectMAP, master SelectMAP, and IEEE 1532 boundary-scan. Mode selection is controlled by M0–M2 pins, and all modes use SRAM-based bitstream loading with optional Triple-DES encryption for secure deployment.
