Frequently asked questions
- Is the XC3S400-5FT256C still in production?
- No. The XC3S400-5FT256C has been discontinued by the manufacturer. Discontinued parts can still be quoted — send a request with the quantity and any date-code requirements.
- Is there a direct replacement for the XC3S400-5FT256C?
- No. The manufacturer's discontinuation notice states there is no direct replacement for the XC3S400-5FT256C. Either the remaining supply is used, or the board is revised around a current device.
- What package is the XC3S400-5FT256C?
- The XC3S400-5FT256C comes in the FT256 package (256-FTBGA, 17 × 17 mm).
- Which versions of the XC3S400 come in industrial temperature?
- The XC3S400-5FT256C is not an industrial-temperature part. 10 XC3S400 parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.XC3S400-4FT256IXC3S400-4FG320IXC3S400-4FG456IXC3S400-4FGG320IXC3S400-4FGG456IXC3S400-4FTG256IXC3S400-4PQ208IXC3S400-4PQG208Iand 2 more
