AMD XC2V250-4FG456I

Overview

XC2V250-4FG456I from Xilinx is a 250K-system-gate Virtex-II platform FPGA in a 456-pin Fine-Pitch BGA (FG456) package, operating across –40°C to +100°C industrial temperature range. It integrates 1,536 Configurable Logic Blocks (CLBs), 48 dedicated 18×18 multipliers, 24 Block SelectRAM™ modules (totaling 432 Kb RAM), and 8 Digital Clock Managers (DCMs). It supports high-speed I/O standards including LVDS, SSTL, HSTL, and PCI-X for telecom and DSP applications.

For engineers reviewing the XC2V250-4FG456I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O capability (200 user I/Os), DCM timing parameters, DCI termination support, and validated alternatives - all aligned with DS031 (v3.5) November 2007 specification.

Technical Context

The XC2V250-4FG456I 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 dual-data-rate (DDR) input/output paths using two phase-opposed clocks generated by integrated DCMs.

Each CLB contains four slices with dual 4-input LUTs, dual flip-flops/latches, carry chains, and horizontal cascading logic. Block SelectRAM resources provide true dual-port 18-Kb RAM configurable from 16K×1 to 512×36, with three read-during-write modes and direct association to adjacent 18×18 multipliers for efficient DSP filtering.

Key Specifications

Pinout & Package

XC2V256-4FG456I uses the FG456 (Fine-Pitch BGA, 1.00 mm pitch, 23 mm × 23 mm) wire-bond package with 456 balls. Pin assignments are defined in Module 4 (Pinout Information) of DS031, covering ball-grid mapping, I/O bank voltage domains (VCCO), auxiliary supply (VCCAUX = 3.3 V), and dedicated configuration/control pins (e.g., CCLK, DONE, M0–M2, PROG_B).

FAQ

What is the maximum number of user I/Os supported by XC2V250-4FG456I?

The XC2V250-4FG456I supports 200 user I/O pins in the FG456 package, as confirmed in Table 6 of DS031 (v3.5). This count excludes 15 dedicated configuration and boundary-scan pins (e.g., CCLK, DONE, TCK, TMS) and VBATT. I/O banks are grouped by VCCO voltage domains to support mixed-standard interfaces.

Does XC2V250-4FG456I support DDR memory interfaces?

Yes, XC2V250-4FG456I supports DDR SDRAM interfaces via its SelectIO-Ultra I/O banks, which include built-in DDR input and output registers. The device complies with SSTL2_I/II and SSTL3_I/II standards, and its DCMs generate precisely phased clocks required for DDR timing closure.

What clock management resources does XC2V250-4FG456I include?

XC2V250-4FG456I integrates 8 Digital Clock Managers (DCMs), each capable of clock de-skew, frequency synthesis (M/D integer ratios), and fine-grained phase shifting (±1/256 of period). These feed 16 global clock multiplexer buffers, enabling robust multi-domain clock distribution in high-speed designs.

Is XC2V250-4FG456I compatible with JTAG boundary-scan testing?

Yes, XC2V250-4FG456I fully supports IEEE 1149.1 boundary-scan via dedicated TCK, TMS, TDI, and TDO pins. It implements EXTEST, INTEST, and HIGHZ instructions, and supports IEEE 1532 for in-system configuration - enabling standardized test, debug, and programming workflows.

What is the core voltage requirement for XC2V250-4FG456I?

XC2V250-4FG456I requires a 1.5 V ±3% core supply (VCCINT) for its 0.15 µm/0.12 µm CMOS logic fabric. It also mandates a dedicated 3.3 V auxiliary supply (VCCAUX) for configuration logic and I/O bank supplies (VCCO) scaled per standard - e.g., 3.3 V for LVTTL, 1.8 V for LVCMOS18.
