640 logic cells, 107 I/O, 144-TQFP
The Lattice LCMXO2-640UHC-4TG144C is a MachXO2 FPGA with 640 logic cells (80 LABs/CLBs) and 107 user I/O — enough for glue logic, bus bridging, or control-plane sequencing in a compact 144-TQFP (20x20 mm) footprint. On-chip memory totals 65536 bits (64 Kbit) of distributed block RAM, supplementing the logic fabric for small FIFOs or register files without external SRAM.
RoHS3 compliant and supplied in a tray package, surface-mount to the 144-TQFP land pattern. The operating temperature range is 0°C to 85°C (TJ), the commercial grade — suitable for indoor equipment, telecom racks, and industrial control cabinets that stay above freezing.
Sourcing and peer fit
The closest peer is the industrial-temperature variant LCMXO2-640UHC-4TG144I, which shares the same 640 logic cells, 107 I/O, and 144-TQFP package but is rated -40°C to 100°C (TJ). The commercial-grade seed part drops into the same board footprint; the only difference is the temperature range, so a BOM swap between the two requires no layout change.
