Product details

Active production — 256-logic-element MachXO2

The LCMXO2-256HC-4SG32I is an active-production MachXO2 FPGA from Lattice, carrying 256 logic elements (32 LABs/CLBs) and 21 user I/O in a 32-UFQFN exposed-pad package measuring 5x5 mm. Industrial temperature rating of -40°C to 100°C (TJ) qualifies it for outdoor or enclosure-based systems where ambient heat or cold-soak is a concern, without active cooling.

Package and board-fit — 32-QFN with thermal pad

Surface-mount mounting type and tray packaging; the 21 I/O count is tightly matched to the small footprint, limiting peripheral expansion but keeping the board area minimal for glue-logic or CPLD-replacement roles.

ROHS3 compliant (no exemption-based restrictions), easing compliance for EU and similar regulated markets.

Frequently asked questions

Will LCMXO2-256HC-4SG32I drop into a panel that was specified around LCMXO2-256HC-6SG32I without rewiring?

Yes — the two parts share the same logic density (256 LEs), I/O count (21), package (32-QFN), supply voltage range, and temperature grade. The -4SG32I is the standard-speed grade; the -6SG32I is the faster speed bin. They are pin-compatible and functionally interchangeable in the same PCB footprint.
