The Spartan™ 3 Generation of FPGAs offers a choice of five platforms, each delivering a unique cost-optimized balance of programmable logic, connectivity, and dedicated hard IP for your low-cost applications.

• Spartan 3A DSP– DSP Optimized
  • For applications where integrated DSP MACs and expanded memory are required
  • Ideal for designs requiring low cost FPGAs for signal processing applications such as military radio, surveillance cameras, medical imaging, etc.
• Spartan 3AN – Non-volatile
  • For applications where non-volatile, system integration, security, large user flash are required
  • Ideal for space-critical or secure applications as well as low cost embedded controllers
• Spartan 3A  –  I/O Optimized
  • For applications where I/O count and capabilities matter more than logic density
  • Ideal for bridging, differential signaling and memory interfacing applications, requiring wide or multiple interfaces and modest processing
• Spartan 3E – Logic Optimized
  • For applications where logic densities matter more than I/O count
  • Ideal for logic integration, DSP co-processing and embedded control, requiring significant processing and narrow or few interfaces
• Spartan 3 – For Highest Density and Pin-Count Applications 
  • For applications where both high logic density and high I/O count are important
  • Ideal for highly-integrated data-processing applications
