On July 25, 2013, Lattice Semiconductor issued Product Change Notification PCN 06B-13, "Notification of Intent to Discontinue LatticeEC/P and LatticeXP Product Families," discontinuing both families in their entirety — all 610 ordering part numbers. The last time buy date was November 25, 2013 and the last shipment date December 31, 2016. Both have passed: any LatticeEC, LatticeECP or LatticeXP part in a design today is running on remaining stock, and the migration question is which part Lattice itself recommended as its successor.
| Family | Devices | Ordering part numbers |
|---|---|---|
| LatticeEC | LFEC1E / 3E / 6E / 10E / 15E / 20E / 33E | 200 |
| LatticeECP | LFECP6E / 10E / 15E / 20E / 33E | 130 |
| LatticeXP | LFXP3C / 3E / 6C / 6E / 10C / 10E / 15C / 15E / 20C / 20E | 280 |
The notice also states it affects any custom devices derived from the listed devices (factory programmed, special test, tape and reel, non-standard speed grade and package, etc.); those derived devices are not printed individually.
Per the notice: LatticeECP2 products replace LatticeEC/P devices, and LatticeXP2 products replace LatticeXP — with a second printed option, a MachXO2 part, for 60 LatticeXP ordering part numbers (all LFXP3C and LFXP6C rows). Every one of the 610 records carries its printed Recommendation 1. The voltage picture, exactly as printed: discontinued parts run at 1.2V (470 records) or 1.8V (140 records, the LatticeXP C devices); every Recommendation 1 runs at 1.2V; every MachXO2 Recommendation 2 runs at 3.3V.

Sample rows are copied verbatim from the paid dataset file (the paid file carries the full family / device / package / voltage detail for both recommendations, dates and a source URL per record).
All 610 records — every discontinued OPN with its printed replacement, package and voltage detail — are in the Lattice Semiconductor EOL & Migration Dataset v4.

Is the LatticeEC family discontinued?
Yes — the LatticeEC, LatticeECP and LatticeXP families were discontinued in their entirety by PCN 06B-13 (July 25, 2013); last time buy November 25, 2013, last shipment December 31, 2016.
What replaces a LatticeEC or LatticeECP part?
LatticeECP2-family parts, printed part-by-part in the notice's own spreadsheet — e.g. LFEC20E-5F484C → LFE2-20E-5F484C.
What replaces a LatticeXP part?
LatticeXP2 parts — and for the 60 LFXP3C / LFXP6C ordering part numbers, the notice also prints a MachXO2 alternative at 3.3V.
Are the replacements drop-in compatible?
No. The notice states they are not pin and/or voltage compatible and require redesign of the board. Check the per-record voltages before planning a migration.
