Procurement FAQs
Same Architecture Variants
Identical logic resources with differences in speed grade, packaging, or I/O count:
XC3S400-4FG320C | XC3S400-4FG320I
Pin-to-pin compatibility must be verified per datasheet.
Design Scaling Consideration
For projects requiring additional logic resources within the same Spartan-3 family:
Resource headroom evaluation recommended before architectural migration.
