Xilinx Spartan-7 and Artix-7 are two popular FPGA families for medium-complexity projects. Let's examine their key differences.
Spartan-7 is the most affordable Xilinx 7-series family, optimized for low power. Artix-7 is a more capable family with transceiver and DSP block support.
| Parameter | Spartan-7 | Artix-7 |
|---|---|---|
| Logic Cells | Up to 102K | Up to 350K |
| DSP Blocks | None | Up to 740 |
| Transceivers | None | Up to 16 (6.6 Gbps) |
| BRAM | Up to 4.86 Mb | Up to 16.5 Mb |
| Power | Low | Medium |
Spartan-7 is suitable for simple logic tasks on a budget. Artix-7 for projects requiring DSP processing, high-speed interfaces and greater logic capacity.
