Product details

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.

Frequently asked questions

Will LCMXO2280C-3TN144C drop into a board designed for LCMXO2280C-3TN100C without rewiring?

No — the 144-TQFP (20x20 mm) and 100-TQFP (14x14 mm) packages are not footprint-compatible. The 113 I/O variant has 40 more pins, so the PCB layout, fan-out, and BOM position must be redesigned. The core logic (2280 LEs, 28 Kbit RAM) and supply range are identical, so the firmware and power tree can carry over.

What is the difference between LCMXO2280C-3TN144C and LCMXO2280C-4TN144C?

The -3 and -4 suffixes denote speed grades — the -4 is the faster bin (typically ~10% higher fMAX at the same voltage and temperature). Both share the same 144-TQFP package, 113 I/O, 2280 LEs, and 28 Kbit RAM. If your timing closure is marginal on the -3, the -4 may save a board spin without changing the layout.
