If the design was validated on a -6 part and the -5 is the available option, confirm that the critical-path propagation delay stays within the setup/hold budget at the target clock rate — the -5 grade typically adds 0.5–1 ns of combinational delay versus -6.","metaTitle":"LCMXO3LF-4300E-5MG121I Lattice MachXO3 FPGA, 4320 LUTs","metaDescription":"Active Lattice MachXO3 FPGA, 4320 logic cells, 100 I/O, 94 Kbit RAM, -40 to 100°C, 121-CSFBGA.
