Product details
Overview
XC6SLX45-N3FG676I from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2,184 Kbits of block RAM, and 180 DSP48A1 slices, configured in a 676-pin Fine-Pitch BGA (FG676) package with -3 speed grade and Industrial temperature range (-40°C to +100°C). It targets cost-sensitive embedded control and interface bridging in industrial automation systems.
For engineers reviewing the XC6SLX45-N3FG676I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (396 user I/Os), LVDS support, SelectIO™ DC and AC characteristics, and compatibility with Xilinx ISE Design Suite v14.7 for synthesis and place-and-route.
Technical Context
The XC6SLX45-N3FG676I implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated routing for high-speed interfaces including DDR2/DDR3 SDRAM controllers and PCI Express® Gen1 endpoints. Its clocking architecture includes four DCMs and two PLLs for internal clock synthesis and jitter reduction.
It supports multiple I/O standards-including LVCMOS, LVTTL, SSTL, HSTL, and differential standards like LVDS and TMDS-with programmable drive strength, slew rate, and on-chip termination. Configuration is performed via SPI, Master Serial, or JTAG modes using external PROM or processor-controlled loading.

Does XC6SLX45-N3FG676I include built-in PCIe Gen1 endpoint functionality?
Yes, XC6SLX45-N3FG676I integrates a hard PCIe Gen1 x1 endpoint block compliant with PCI Express Base Specification v1.1. It requires no external PHY and supports enumeration, configuration space access, and memory-mapped I/O transactions. The XC6SLX45-N3FG676I does not support PCIe Gen2 or higher speeds.
What configuration modes are supported by XC6SLX45-N3FG676I?
XC6SLX45-N3FG676I supports Master Serial, Slave Serial, Slave Parallel, JTAG, and SPI Flash configuration modes. Configuration bitstream loading is initiated via PROGRAM_B and controlled by INIT_B and DONE signals. The XC6SLX45-N3FG676I does not support dual-boot or fallback configuration without external logic.
Is XC6SLX45-N3FG676I qualified for automotive applications?
No, XC6SLX45-N3FG676I is specified for Industrial temperature range (-40°C to +100°C) and is not AEC-Q100 qualified. While used in some automotive-adjacent industrial systems, it lacks automotive-grade screening, failure reporting, and documentation required for safety-critical vehicle subsystems. The XC6SLX45-N3FG676I is not recommended for ADAS or powertrain applications.
What software tools are required to develop for XC6SLX45-N3FG676I?
XC6SLX45-N3FG676I requires Xilinx ISE Design Suite v14.7 for full synthesis, implementation, and bitstream generation. Vivado does not support Spartan-6 devices. The XC6SLX45-N3FG676I bitstream can be programmed via iMPACT or third-party JTAG tools compatible with IEEE 1149.1 boundary-scan.
