Logic density and I/O count — what they mean for the BOM line
The LCMXO2280C-3TN144C packs 2280 logic elements (LUT4-based) across 285 LABs/CLBs, with 28 Kbit of distributed RAM on-chip — enough for glue-logic consolidation, small state machines, or a 32-bit microcontroller bus bridge without external SRAM. 113 user I/O in a 144-TQFP (20x20 mm) means this part can handle a 16-bit data bus plus address, control, and a handful of peripherals before the pin count becomes the constraint. The 0.5 mm pitch TQFP is a standard 4-layer board fan-out; two-layer designs will struggle with the inner rows.
Supply rails and temperature — the operating envelope
Commercial temperature grade (0°C to 85°C junction) is the standard indoor/controlled-environment band — suitable for telecom racks, industrial controllers, and test equipment that stays above freezing. No AEC-Q or military screening on this variant.
