Product details
Overview
XC6SLX45-N3FG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA with 43,661 logic cells, 2.1 Mb of block RAM, and 186 DSP48A1 slices, configured in a 484-pin Fine-Pitch BGA (FG484) package rated for industrial temperature range (–40°C to +100°C). It serves as a reconfigurable logic fabric for embedded control, video processing, and communication interface bridging in space-constrained industrial systems.
For engineers reviewing the XC6SLX45-N3FG484C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (348 user I/Os), LVDS support (up to 24 differential pairs), DCI termination capability, and compatibility with Xilinx ISE Design Suite v14.7 for synthesis and place-and-route.
Technical Context
The XC6SLX45-N3FG484C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry logic. It supports multi-standard I/O banks with programmable drive strength (2–24 mA), slew rate control, and on-die termination (DCI) for SSTL, HSTL, and LVCMOS interfaces.
It integrates six CMT clock management tiles-each containing two DCMs-for jitter reduction, frequency synthesis, and phase alignment across multiple clock domains. The device lacks integrated transceivers but supports source-synchronous interfaces up to 1 Gbps via SelectIO technology.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC6SLX45-3FG484C | Speed grade -3 (vs. -N3); higher maximum clock frequency (540 MHz vs. 400 MHz for DCM outputs) | Requires tighter timing constraints and may need revised PCB routing for signal integrity | Preferred when design requires higher clock rates or lower latency in critical paths |
| XC6SLX75-2FG484C | Larger logic capacity (74,637 LUTs), more BRAM (3.8 Mb), and additional DSP slices (228) | Higher power consumption and larger die size; may exceed thermal budget in compact enclosures | Chosen when design scales beyond XC6SLX45-N3FG484C resource limits but retains same package and I/O compatibility |
Compared with XC6SLX45-N3FG484C, the -3 speed grade offers higher performance at increased timing closure effort, while the XC6SLX75-2FG484C provides headroom for feature expansion without changing board layout-both require validation of power delivery and thermal dissipation in target systems.

FAQ
What is the maximum operating frequency of the XC6SLX45-N3FG484C?
The XC6SLX45-N3FG484C has a speed grade of -N3, specifying a maximum DCM output frequency of 400 MHz and a maximum system clock frequency of 333 MHz under typical industrial conditions. These values are validated in Xilinx DS162 and depend on design placement, routing, and I/O standards used. The XC6SLX45-N3FG484C does not support transceiver-based serial protocols above 1 Gbps.
Does the XC6SLX45-N3FG484C support JTAG programming?
Yes, the XC6SLX45-N3FG484C supports IEEE 1149.1 JTAG boundary-scan through dedicated TCK, TMS, TDI, and TDO pins. It enables in-system programming, debugging, and verification using Xilinx iMPACT or Vivado tools. JTAG configuration is fully supported alongside Master SPI and Slave SelectMAP modes for the XC6SLX45-N3FG484C.
Can the XC6SLX45-N3FG484C operate at 3.3 V I/O voltage?
Yes, the XC6SLX45-N3FG484C supports 3.3 V I/O operation in any I/O bank powered by VCCO = 3.3 V, provided VCCAUX is supplied at 1.2 V and VCCINT at 1.2 V. This is confirmed in the Spartan-6 DC and Switching Characteristics datasheet (DS162), Table 13. The XC6SLX45-N3FG484C maintains full timing compliance at 3.3 V across its industrial temperature range.
Is the XC6SLX45-N3FG484C pin-compatible with other Spartan-6 FG484 devices?
Yes, all Spartan-6 FPGAs in the FG484 package-including XC6SLX45-N3FG484C, XC6SLX75-2FG484C, and XC6SLX100-3FG484C-share identical ball maps and I/O banking structure. Pin functions are consistent across speed grades and logic densities, enabling hardware reuse when upgrading within the same package footprint.
What configuration modes does the XC6SLX45-N3FG484C support?
The XC6SLX45-N3FG484C supports Master SPI, Slave SelectMAP, JTAG, and Serial Peripheral Interface (SPI) flash configuration. Configuration is initiated via PROGRAM_B and controlled by INIT_B and DONE pins. Mode selection is determined by MODE pins (M0–M2), with settings documented in DS162 Section 4. The XC6SLX45-N3FG484C does not support BPI or NAND flash boot modes.
