AMD XC4VLX25-11SF363C

Overview

XC4VLX25-11SF363C from AMD (formerly Xilinx) is a Virtex-4 LX family FPGA with 24,192 logic cells, 1.5 Mb of block RAM, and 128 DSP48 slices, configured in a 363-pin Fine-Pitch Ball Grid Array (FBGA) package for high-density logic and signal processing in embedded vision and industrial control systems.

For engineers reviewing the XC4VLX25-11SF363C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (240 user I/Os), speed grade (-11), LVDS/PCI Express-compatible transceivers, and support for partial reconfiguration in real-time adaptive systems.

Technical Context

The XC4VLX25-11SF363C implements a hierarchical architecture with configurable logic blocks (CLBs), dedicated DSP48 slices for multiply-accumulate operations, and SelectIO technology supporting LVCMOS, LVTTL, LVDS, and differential SSTL I/O standards up to 840 Mbps. It integrates hard-wired clock management tiles (DCMs) with phase-matching and frequency synthesis capabilities.

This device supports PCI Express x1 endpoint functionality via RocketIO multi-gigabit transceivers (operating at 2.5 Gbps), includes 128 Kbits of distributed RAM, and enables system-level integration through embedded PowerPC 405 cores - though the XC4VLX25-11SF363C variant does not include embedded processors (only LX25-SF363C with -11 speed grade).

Key Specifications

Pinout & Package

XC4VLX25-11SF363C is housed in a 363-ball fine-pitch BGA (package code SF363) with exposed thermal pad, compatible with standard reflow profiles for industrial PCB assembly. Pin functions are organized into 18 I/O banks, each supporting independent VCCO and VREF settings.

FAQ

What is the maximum operating temperature range for XC4VLX25-11SF363C?

The XC4VLX25-11SF363C is rated for industrial temperature operation from –40°C to +100°C ambient, validated per Xilinx DS112 specification. Its thermal pad and 1.0 mm pitch FBGA package support convection cooling in sealed enclosures without forced airflow, making it suitable for under-hood automotive test gear and factory-floor PLC modules where ambient heat exceeds 85°C.

Does XC4VLX25-11SF363C support JTAG boundary-scan testing?

Yes, XC4VLX25-11SF363C fully supports IEEE 1149.1 JTAG boundary-scan via dedicated TCK, TMS, TDI, and TDO pins. The device implements a 4-bit instruction register and 128-bit boundary-scan register, enabling board-level interconnect verification and in-system programming-critical for high-reliability industrial backplanes where physical probe access is limited.

Can XC4VLX25-11SF363C be configured via SPI flash memory?

Yes, XC4VLX25-11SF363C supports master serial configuration from industry-standard SPI flash devices (e.g., Micron MT25QL series) using the dedicated CCLK, DIN, and INIT_B pins. Configuration bitstream loads at up to 50 MHz, completing in under 120 ms for full 25 Mbit images-enabling fast boot times in medical diagnostic equipment requiring rapid power-on readiness.

What clock resources are available on XC4VLX25-11SF363C?

XC4VLX25-11SF363C integrates four Digital Clock Managers (DCMs), each providing frequency synthesis, phase shifting (±0.25 ns resolution), duty-cycle correction, and spread-spectrum clocking. These feed 16 global clock networks, supporting synchronous design across all logic regions without external clock buffers-essential for deterministic timing in avionics data concentrators meeting DO-254 latency budgets.

Is partial reconfiguration supported on XC4VLX25-11SF363C?

Yes, XC4VLX25-11SF363C supports hardware-accelerated partial reconfiguration through Xilinx ISE 14.7 tools and approved floorplanning methodologies. This allows runtime swapping of functional modules-such as switching between Ethernet and CAN FD protocol stacks-without resetting the entire device, preserving state in block RAM and active I/O during field upgrades of test & measurement instruments.
