Procurement FAQs

How can we verify the current stock availability for the XC3S400-5TQG144C given its mature lifecycle status?

Due to the 'Mature/Legacy' status of the Spartan-3 series, real-time availability requires confirmation from our procurement team. Stock levels are subject to verification against existing factory buffers and authorized distributor inventories to ensure the 144-LQFP package is accessible for new orders.

Are there any direct plain-text alternatives or cross-reference parts available for this specific FPGA?

Identifying a drop-in replacement for the XC3S400-5TQG144C requires confirmation of your specific timing and voltage requirements. Any potential cross-reference or pin-compatible alternative is subject to verification by our technical engineering team to ensure full functional parity with the original 144-pin LQFP specification.

What is the process for obtaining a Certificate of Conformance (CoC) for legacy components like the XC3S400-5TQG144C?

The provision of a Certificate of Conformance (CoC) for this legacy device requires confirmation at the time of RFQ. Traceability documentation and the ability to issue a formal CoC are subject to verification based on the specific date code and the sourcing channel used for the 144-LQFP package.

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
