Highlighted values are higher. LUT counts are shown as published; the LUT4 equivalent is an approximation to compare different LUT types, see how FPGA vendors count logic. Add up to two more devices to this comparison.

Key differences

Both devices offer similar logic capacity: 256 and 256 LUT4 equivalents.

The LCMXO2-256 is designed with Lattice Diamond; open source: Yosys + nextpnr-machxo2 (experimental) with Project Trellis and the LCMXO256C with Lattice Diamond.
