Sourcing Note

The 3S200 is a legacy Spartan-3 device — 200,000 system gates, 4,320 logic cells and 141 I/O in a 28 x 28 mm PQFP. DigiKey lists this exact variant as Obsolete, so supply is remaining market stock only, checked lot by lot, and date code and provenance are the whole conversation. The commercial C grade is specified 0°C to +85°C; this is the -4 speed grade in the lead-free PQG208 package, and it must not be blurred into the industrial grade or the faster -5 speed grade. Send your quantity and date-code requirement and we check current availability for this exact variant. Related parts: XC3S400-4PQG208I and XC3S500E-4PQG208C.

FAQ

The part is obsolete — what should I check before buying?

Date code and provenance first. On obsolete Spartan-3 stock, ask for date-code and label photos of the actual lot and traceability documents before payment, and third-party testing if your volume justifies it.

Can the XC3S200-4PQG208C replace an XC3S200-4PQG208I in an existing design?

Only if the design was qualified over the commercial temperature range. The I grade is specified -40°C to +100°C; the C grade on this page covers 0°C to +85°C. Same silicon and package does not make the grades interchangeable — check it against your original qualification records.

How can I verify the condition of a lot before paying?

Ask for date-code and label photos of the actual lot, traceability documents, and third-party testing if your volume justifies it. We provide the first two before payment and support the third on request.
