Not every FPGA is the right FPGA. The one that wins a design socket is the one that matches the application — in logic density, speed, temperature rating, power budget, and price. That’s why PCX stocks a curated selection of AMD programmable logic devices, each targeting a specific engineering sweet spot.
Here are five AMD FPGAs and SoCs we’ve stocked deep because our customers keep asking for them. Whether you’re building industrial controls, processing video, or deploying edge AI, there’s a part here that fits.
1. XC6SLX100-2FGG484C — The Workhorse
Spartan-6 LX | 101K Logic Cells | -2 Speed | Commercial Temp | $223.60
The most popular Spartan-6 for a reason. The LX100 in -2 speed grade hits the sweet spot between performance, power, and price for high-volume production designs. With 101,261 logic cells, 180 DSP slices, and integrated DDR3 controllers, it handles everything from industrial motor drives to video processing pipelines.
If your design comfortably meets timing and you’re optimizing for cost-per-unit, this is the part.

2. XC6SLX100-3FGG484C — The Speed Demon
Spartan-6 LX | 101K Logic Cells | -3 Speed (Fastest) | Commercial Temp | $234.76
Same silicon, same pinout, but binned at the highest performance tier. The -3 speed grade delivers the fastest timing the Spartan-6 LX100 can achieve — critical for designs pushing clock boundaries, latency-sensitive trading systems, or high-speed serial links. Drop-in upgrade from the -2 with zero board changes.

3. XC7Z035-2FBG676E — The Powerhouse SoC
Zynq-7000 | Dual ARM Cortex-A9 @ 800MHz + 275K FPGA Cells | 676-FCBGA | $1,705.00
This is the part that eliminates the “processor + FPGA” two-chip architecture. The Zynq-7035 fuses a hardened dual-core ARM Cortex-A9 with Kintex-class FPGA fabric, 900 DSP slices, and 8 multi-gigabit transceivers. Run Linux on the ARM side while processing data at wire speed in the FPGA. One chip. One power supply. One board.
Ideal for 5G base stations, autonomous vehicle sensor fusion, medical imaging, and industrial robotics.

4. XC6SLX75-3FGG484I — The Survivor
Spartan-6 LX | 75K Logic Cells | -3 Speed (Fastest) | Industrial Temp (-40C to +100C) | $195.22
When your product lives in places that destroy consumer electronics — desert oil rigs, Arctic telecom towers, underground mines — this is the FPGA you spec. The rare combination of fastest speed grade and industrial temperature qualification means you get peak performance without compromising on environmental resilience. Every unit is tested across the full -40C to +100C range.

5. XC7S100-2FGGA484C — The Next Generation
Spartan-7 | 102K Logic Cells | 28nm | -2 Speed | Commercial Temp | $152.81
The natural evolution for Spartan-6 designers. Built on 28nm technology, the Spartan-7 XC7S100 delivers ~50% lower power, faster fabric speeds, and access to the modern Vivado toolchain — all at a lower price point than the Spartan-6 LX100 it effectively replaces. If you’re starting a new design today, this is where you should start.
