Product details
Overview
XC6SLX45-3FG676I from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2.1 Mb of block RAM, 186 DSP48A1 slices, and operates at -3 speed grade with industrial temperature range (-40°C to +100°C). It is used in industrial motor control, embedded vision preprocessing, and protocol bridging applications.
For engineers reviewing the XC6SLX45-3FG676I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (480 user I/Os), LVDS support, SelectIO™ voltage flexibility (1.2V–3.3V), and integrated clock management (DCM and PLL).
Technical Context
The XC6SLX45-3FG676I implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic. It integrates dual-clock management units (DCMs) and one PLL for clock synthesis, phase shifting, and jitter reduction.
I/O banks are organized into eight groups supporting independent voltage domains and multiple standards including LVCMOS, LVTTL, PCI, HSTL, SSTL, and differential LVDS. Each bank supports programmable slew rate and drive strength.

FAQ
What is the maximum supported LVDS data rate for XC6SLX45-3FG676I?
The XC6SLX45-3FG676I supports LVDS signaling up to 1,080 Mbps per differential pair, validated under -3 speed grade conditions with proper PCB layout and termination. This rate applies to both input and output directions and is guaranteed across the full industrial temperature range. The XC6SLX45-3FG676I achieves this using calibrated output drivers and programmable input termination within its SelectIO™ banks.
Does XC6SLX45-3FG676I include hard IP for Ethernet MAC functionality?
No, the XC6SLX45-3FG676I does not include a hard Ethernet MAC. It provides MII/RMII/GMII interface support via configurable I/O and soft-core implementations (e.g., Xilinx LogiCORE IP Ethernet MAC). The XC6SLX45-3FG676I does integrate hard PCIe Gen1 x1 endpoint logic and DDR2/DDR3 memory controllers, but Ethernet functionality requires soft logic or external PHY integration.
Can XC6SLX45-3FG676I operate with a single 1.2V supply for core logic?
Yes, the XC6SLX45-3FG676I core voltage (VCCINT) is fixed at 1.2V and requires a dedicated, well-regulated 1.2V supply. This rail powers the FPGA fabric, CLBs, and internal routing. Other supplies-including VCCAUX (2.5V), VCCO (1.2–3.3V), and VREF-are independently configured per bank and function, but VCCINT must remain at 1.2V ±3% for reliable operation of the XC6SLX45-3FG676I.
Is partial reconfiguration supported on XC6SLX45-3FG676I?
Yes, partial reconfiguration is supported on the XC6SLX45-3FG676I using Xilinx ISE Design Suite tools and appropriate bitstream generation flow. This capability allows dynamic logic updates in designated regions without resetting the entire device. The XC6SLX45-3FG676I's architecture includes frame-based configuration memory access control, enabling safe runtime updates while maintaining active I/O and clock domains.
What configuration modes are available for XC6SLX45-3FG676I?
The XC6SLX45-3FG676I supports Master Serial, Slave Serial, Slave Parallel, and JTAG configuration modes. Configuration bitstreams can be loaded from SPI flash (Master Serial), external microcontroller (Slave Parallel/Serial), or Xilinx programming hardware (JTAG). Mode selection is controlled by mode pins (M[2:0]) at power-up, and all modes are fully supported in industrial temperature operation of the XC6SLX45-3FG676I.
