AMD XC4VLX25-10SFG363I

Overview

XC4VLX25-10SFG363I from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA with 24,192 logic cells, 1.2 Mb of block RAM, and 192 DSP48 slices. It features SelectIO™ technology supporting LVDS, SSTL, HSTL, and GTL interfaces, and is packaged in a 363-pin Fine-Pitch Flip-Chip BGA (SFG). It is used in high-performance digital signal processing and reconfigurable computing systems.

For engineers reviewing the XC4VLX25-10SFG363I datasheet, pinout, applications, or equivalent options, key selection considerations include speed grade (-10), I/O voltage flexibility (1.2 V to 3.3 V), thermal performance in SFG363, and compatibility with Xilinx ISE 14.7 design tools.

Technical Context

The XC4VLX25-10SFG363I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated carry chains, and distributed RAM. It integrates hard-wired clock management tiles (CMTs) containing DCMs and PLLs for low-jitter clock synthesis and phase alignment.

It supports multi-standard I/O with programmable slew rate, drive strength, and on-chip termination. Configuration is performed via Master SelectMAP, Slave SelectMAP, or JTAG, with bitstream encryption available using AES-128.

FAQ

What is the operating temperature range for XC4VLX25-10SFG363I?

The XC4VLX25-10SFG363I is rated for industrial temperature operation from –40°C to +100°C. This range is validated per Xilinx DS112 specification and applies to junction temperature under specified airflow and power dissipation conditions. The SFG363 package's thermal pad enhances heat transfer to the PCB, supporting reliable operation at the upper limit when mounted on 4-layer boards with thermal vias.

Does XC4VLX25-10SFG363I support partial reconfiguration?

No, XC4VLX25-10SFG363I does not support hardware-accelerated partial reconfiguration. While the Virtex-4 architecture permits manual bitstream manipulation, Xilinx did not implement dynamic module swapping or frame-level reconfiguration logic in this device. Full reconfiguration via JTAG or SelectMAP is required for any functional change, and the XC4VLX25-10SFG363I datasheet explicitly lists only complete configuration modes.

What configuration memory options are compatible with XC4VLX25-10SFG363I?

XC4VLX25-10SFG363I supports serial PROMs (Xilinx XCFxx, Atmel AT17xx, ST M25Pxx) and parallel NOR flash (Spansion S29GLxxx) in Master SelectMAP mode. Configuration bitstream size is 3.2 MB for typical designs. The device requires 3.3 V VCCO on Bank 0 during configuration, and all supported memories must meet tSU/tH timing relative to CCLK as defined in DS112 Table 37.

Is XC4VLX25-10SFG363I RoHS compliant?

Yes, XC4VLX25-10SFG363I is RoHS-6 compliant (lead-free, mercury-free, cadmium-free, hexavalent chromium-free, PBB-free, PBDE-free) per Xilinx specification document DS112 Revision 2.1. The SFG363 package uses matte tin finish on solder balls and halogen-free molding compound, meeting JEDEC J-STD-020D moisture sensitivity level 3 requirements.

Can XC4VLX25-10SFG363I interface directly with DDR2 SDRAM?

Yes, XC4VLX25-10SFG363I supports DDR2 SDRAM interfaces through its SelectIO banks configured for SSTL-18 I/O standard. It delivers controlled impedance, calibrated output drive, and programmable input delay for DQS capture. Reference designs (e.g., XAPP695) confirm reliable 400 Mbps data rates using 16-bit wide interfaces with on-die termination enabled in compatible DDR2 components.
