AMD XC4VLX25-10SF363I

Overview

XC4VLX25-10SF363I 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, 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 XC4VLX25-10SF363I datasheet, pinout, applications, or equivalent options, key selection criteria include speed grade (-10), I/O count (240 user I/Os), LVDS support, SelectIO™ voltage range (1.2 V to 3.3 V), and thermal performance in extended industrial temperature range (-40°C to +100°C).

Technical Context

The XC4VLX25-10SF363I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP48 slices for multiply-accumulate operations, and flexible SelectIO™ technology supporting single-ended and differential standards including LVCMOS, LVTTL, and LVDS. It integrates clock management tiles (CMT) with DCMs for jitter reduction and phase alignment.

This device supports partial reconfiguration and features on-chip termination, programmable slew rate, and drive strength control per I/O bank. Its -10 speed grade guarantees timing closure at 500 MHz system clock frequency with 1.2 V core voltage and operation across the full industrial temperature range.

FAQ

What is the maximum operating frequency supported by XC4VLX25-10SF363I?

The XC4VLX25-10SF363I carries a -10 speed grade, guaranteeing internal logic paths operate reliably up to 500 MHz under worst-case voltage and temperature conditions. This rating is validated across the full industrial temperature range (-40°C to +100°C) and assumes proper 1.2 V core supply regulation and PCB layout adherence to Xilinx's Virtex-4 design guidelines.

Does XC4VLX25-10SF363I support LVDS signaling?

Yes, XC4VLX25-10SF363I supports LVDS input and output standards via its SelectIO™ technology. Each of the 16 I/O banks can be independently configured for LVDS operation with programmable internal termination, eliminating the need for external 100 Ω resistors. LVDS functionality is fully documented in the Virtex-4 User Guide and verified in production silicon.

What configuration modes are supported by XC4VLX25-10SF363I?

XC4VLX25-10SF363I supports Master Serial, Slave Serial, Master SelectMAP, Slave SelectMAP, and JTAG configuration modes. Configuration bitstreams may be loaded from SPI flash, PROM, or host processor via parallel or serial interfaces. The DONE pin signals successful initialization, and PROGRAM_B initiates reconfiguration.

Is XC4VLX25-10SF363I qualified for extended temperature operation?

Yes, XC4VLX25-10SF363I is rated for operation from -40°C to +100°C and is marked with the "I" suffix denoting industrial temperature grade. This qualification includes full characterization of timing, I/O drive strength, and configuration stability across the range, with no derating required for thermal performance in sealed enclosures.

How many DSP48 slices does XC4VLX25-10SF363I contain?

XC4VLX25-10SF363I contains 192 dedicated DSP48 slices. Each slice provides a 18 × 18 signed multiplier, a 48-bit accumulator, and optional pre-adder functionality-enabling high-efficiency FIR filtering, FFT computation, and motor control algorithms without consuming general-purpose logic resources.
