Active production — sourcing reality for LCMXO256C-3TN100I
RoHS3 compliant with no exemptions, so the part clears EU and other regulated markets without a waiver process.
Logic density, I/O, and supply flexibility
256 logic cells across 32 LABs/CLBs — this is the smallest MachXO density tier, sized for glue-logic consolidation, CPLD replacement, or simple state-machine control.
Package and board-fit: 100-TQFP (14x14 mm)
The 100-TQFP body is 14x14 mm with 0.5 mm pitch — a standard fine-pitch QFP that routes on a two-layer board when the I/O count is below ~60, but the full 78 I/O fan-out typically needs four layers to avoid signal-integrity issues on the inner rows. The exposed paddle (if present on this variant) is not a thermal pad; the part's static power is low enough that a standard QFP footprint without thermal vias is adequate.
