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.","metaTitle":"LCMXO2-640UHC-4TG144C Lattice MachXO2 FPGA, 640 LEs, 107 I/O","metaDescription":"Lattice LCMXO2-640UHC-4TG144C MachXO2 FPGA, 640 logic cells, 107 I/O, 64 Kbit RAM, 144-TQFP, active production, RoHS3 compliant.
