Obsolete device
LCMXO1200C-5M132 replacement options
The Lattice LCMXO1200C-5M132 has been discontinued by the manufacturer. There are two ways forward, and for most people reading this the first one is the answer: keep the design and source the part. Changing device means a board revision, so it is only worth it if you are redesigning anyway.
1. Keep the design — source the LCMXO1200C-5M132
Discontinued parts are still traded. We hold 1 orderable LCMXO1200C-5M132 part — send the exact code and quantity and we'll come back with stock and pricing, including date-code and traceability requirements.

A different package or speed grade of the same device is the closest thing to a like-for-like change: the silicon is the same, so only the footprint or timing differs. It still needs checking against your board.
2. Redesigning? Current devices of similar capacity
Lattice devices still in production with comparable logic capacity, closest first. These are a shortlist to evaluate, not equivalents: none of them is pin-compatible with the LCMXO1200C-5M132, and none is recommended by the manufacturer as its successor. We select them by capacity from the data on this site.

What to check before changing device
Footprint and pinout
Ball count, pitch and pin assignment all differ between families. A new device means a new layout.
I/O voltages and banks
Supported I/O standards, bank voltages and the number of banks change between generations.
Core and I/O supplies
Newer devices usually run a lower core voltage and need a different power tree.
Configuration
Flash type, configuration mode and boot timing are family-specific.
Tools and IP
The design has to be rebuilt in the current toolchain, and IP cores may need replacing or re-licensing.
Temperature and lifetime
Check the grade you need exists, and how long the new family is expected to stay in production.
Where a design cannot be revised — certified equipment, long-life industrial and defence builds — sourcing the original is normally the cheaper route, even at obsolete pricing.
