Product details

Logic density and I/O in a 5x5 mm footprint

The LCMXO2-256ZE-1SG32I: 256 logic elements (LUT4-based) organised into 32 LABs/CLBs — this is the smallest density tier in the MachXO2 family, sized for glue-logic, I/O expansion, or control-plane sequencing where a full FPGA array would be overkill.

Core supply is 1.14 V to 1.26 V, the low-power ZE (zero-energy) operating point — this is the 1.2 V nominal rail, distinct from the 2.375 V core used on the HC siblings (LCMXO2-256HC-6SG32I, LCMXO2-256HC-4SG32I).

Supplied in tray packaging; surface-mount assembly with standard lead-free reflow profiles.

Frequently asked questions

Where can I buy LCMXO2-256ZE-1SG32I and get a price?

No stock-holding claim is made; each lot is sourced fresh for your BOM line.

Will LCMXO2-256ZE-1SG32I drop into a board laid out for LCMXO2-256HC-6SG32I?

The package (32-UFQFN, 5x5 mm) and pinout are identical across the MachXO2 256-LUT variants, so the mechanical fit is the same. The critical difference is the core supply: the ZE runs on 1.14-1.26 V, while the HC requires 2.375 V. The board must have the correct voltage rail — swapping without changing the supply will not work.

What is the closest functional second-source for LCMXO2-256ZE-1SG32I?

Within the MachXO2 family, the LCMXO2-256ZE-3SG32C is the same 1.2 V ZE variant but with a commercial temperature range (0°C to 85°C). For industrial temperature, the LCMXO2-256HC-6SG32I or LCMXO2-256HC-4SG32I are functional equivalents at 2.375 V core — a supply-rail change is required.
