FAQ Section
Q: What's the difference between -2 and -3 speed grades?
A: The -2 grade offers 20% faster performance (500MHz vs 400MHz) but consumes 15% more power than -3 grade.
Q: Can it interface with modern DDR4 memory?
A: No, the Spartan-6 family supports up to DDR3-800. For DDR4, consider Artix-7 or newer families.
