Frequently asked questions
- Is there a direct replacement for the XA3S400A-4FTG256I?
- No. The manufacturer's discontinuation notice states there is no direct replacement for the XA3S400A-4FTG256I. Either the remaining supply is used, or the board is revised around a current device.
- What package is the XA3S400A-4FTG256I?
- The XA3S400A-4FTG256I comes in the FTG256 package (256-FTBGA, 17 × 17 mm).
- Which versions of the XA3S400A come in industrial temperature?
- The XA3S400A-4FTG256I is itself an industrial-temperature part (-40 °C to 100 °C, junction). One other XA3S400A part is industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.XA3S400A-4FGG400I
