Frequently asked questions
- Is the LFEC3E-4FN256C still in production?
- No. The LFEC3E-4FN256C has been discontinued by the manufacturer. Discontinued parts can still be quoted — send a request with the quantity and any date-code requirements.
- What package is the LFEC3E-4FN256C?
- The LFEC3E-4FN256C comes in the FN256 package (256 pins).
- Which versions of the LFEC3E come in industrial temperature?
- The LFEC3E-4FN256C is not an industrial-temperature part. 8 LFEC3E parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.LFEC3E-3FN256ILFEC3E-4FN256ILFEC3E-3QN208ILFEC3E-4QN208ILFEC3E-3TN100ILFEC3E-4TN100ILFEC3E-3TN144ILFEC3E-4TN144I
