Frequently asked questions
- Is the XC3S1000-4FTG256I still in production?
- No. The XC3S1000-4FTG256I 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 XC3S1000-4FTG256I?
- No. The manufacturer's discontinuation notice states there is no direct replacement for the XC3S1000-4FTG256I. Either the remaining supply is used, or the board is revised around a current device.
- What package is the XC3S1000-4FTG256I?
- The XC3S1000-4FTG256I comes in the FTG256 package (256-FTBGA, 17 × 17 mm).
- Which versions of the XC3S1000 come in industrial temperature?
- The XC3S1000-4FTG256I is itself an industrial-temperature part (-40 °C to 100 °C, junction). 7 other XC3S1000 parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.XC3S1000-4FG320IXC3S1000-4FG456IXC3S1000-4FG676IXC3S1000-4FGG320IXC3S1000-4FGG456IXC3S1000-4FGG676IXC3S1000-4FT256I
