4320 LEs in a 144-TQFP — right-sized for board-level glue
The LCMXO2-4000HC-4TG144I is a Lattice MachXO2 FPGA packing 4320 logic elements and 114 user I/O in a 144-TQFP (20x20 mm) package. That logic density lands it between a large CPLD and a small FPGA — enough fabric to absorb a handful of 74-series glue chips, a few state machines, and some bus translation without reaching for a bigger device. With 94208 total RAM bits on-chip, there is room for small FIFOs, look-up tables, or configuration shadow registers without external SRAM. The 540 LABs/CLBs give the place-and-route tool enough granularity to pack the logic efficiently.
Supply and temperature — industrial range, wide Vcc window
The operating temperature of -40°C to 100°C (TJ) qualifies it for industrial environments — motor drives, outdoor telecom, or factory-floor controllers where the junction sees 85°C ambient plus self-heating.
Active production and compliance
Lattice lists this part as Active in production, with ROHS3 compliance.
