Some FPGAs come and go. The Spartan-6 LX100 just keeps showing up in new designs — year after year, across industries, from factory floors to satellite ground stations. There’s a reason for that.
The AMD XC6SLX100-2FGG484C packs 101,261 logic cells into a 484-ball FBGA package that costs a fraction of what you’d pay for a comparable Kintex or Virtex device. It’s the engineering equivalent of a Swiss Army knife: versatile enough for almost anything, reliable enough that you’ll stop thinking about it once it’s in your design.
What Makes the Spartan-6 LX100 a Legend
When AMD (then Xilinx) launched the Spartan-6 family, they hit a nerve. Engineers needed FPGAs that were powerful enough for real work but priced for high-volume production. The LX100 sits right at the sweet spot — big enough to absorb complex designs, small enough to keep your BOM reasonable.
Here’s what you’re working with:
- 101,261 logic cells across 15,822 slices — that’s enough fabric for multi-channel video processing, complex state machines, or entire protocol stacks
- 180 DSP48A1 slices — dedicated multiply-accumulate hardware for DSP-intensive workloads like FIR filters, FFTs, and motor control algorithms
- 4,824 Kbits of block RAM — on-chip memory that eliminates the need for external SRAM in many designs
- 326 user I/O pins — with support for DDR3, LVDS, SSTL, and virtually every I/O standard you’ll encounter
- Integrated memory controllers — hardened DDR/DDR2/DDR3 interfaces that save logic resources and simplify board layout
The -2 Speed Grade: The Pragmatist’s Choice
The -2 speed grade is where most production designs land. It delivers solid performance with excellent power efficiency — the kind of part you spec when you need 10,000 units and can’t afford thermal surprises in the field. If you’re building something that needs to run 24/7 for years, this is the bin you want.
Need more headroom? The -3 speed grade variant (XC6SLX100-3FGG484C) is also available from PCX for designs that push timing limits.

Development Ecosystem
The Spartan-6 is supported by AMD’s ISE Design Suite, which — despite being succeeded by Vivado for newer families — remains a mature, battle-tested toolchain. The IP library is extensive: PCIe endpoints, Ethernet MACs, UART/SPI/I2C controllers, memory interfaces, and DSP building blocks are all available as verified cores.
If you’re starting a new design and want to future-proof with modern tools, consider the Spartan-7 XC7S100-2FGGA484C — same price class, 28nm process, and full Vivado support.
In Stock at PCX
The global semiconductor supply chain has been unpredictable. Lead times on Spartan-6 parts have stretched to 52+ weeks from some distributors. PCX has the XC6SLX100-2FGG484C in stock right now — ready to ship, 100% authorized, fully traceable. Don’t let supply shortages stall your production line.
