LCMXO2-640HC-4SG48C

Product Overview

The LCMXO2-640HC-4SG48C is a MachXO2 field programmable gate array from Lattice Semiconductor Corporation. It is packaged in a 48-VFQFN exposed pad, 48-QFN (7x7), surface-mount device package. The FPGA provides 40 I/O, 640 logic elements or cells, 80 LABs or CLBs, and 18432 total RAM bits. It operates from a 2.375V to 3.465V supply and is specified for a junction temperature range of 0°C to 85°C. This configuration supports embedded logic functions that require programmable resources, a defined I/O count, and a compact QFN footprint.

Key Features

• 40 I/O pins for external digital interfacing
• 640 logic elements or cells for programmable logic implementation
• 80 LABs or CLBs as the logic block organization
• 18432 total RAM bits for on-chip data storage
• 2.375V to 3.465V supply voltage range
• 0°C to 85°C operating junction temperature range
• 48-VFQFN exposed pad package, 48-QFN (7x7), surface mount

Applications

• Embedded control logic in general-purpose electronic assemblies
• Glue logic and signal routing between digital components
• Programmable interface adaptation for digital subsystems
• Small-scale data buffering using available on-chip RAM bits
• Compact surface-mount FPGA implementations in space-constrained boards

Design & Procurement Notes

Designers should confirm that the PCB footprint and thermal path support the 48-VFQFN exposed pad package and that the junction temperature remains within 0°C to 85°C. The system supply should remain within 2.375V to 3.465V during operation, and the 40 I/O pins should be checked against required external interfaces. Logic utilization should be evaluated against the 640 logic elements or cells, 80 LABs or CLBs, and 18432 total RAM bits before implementation. For procurement, match the exact manufacturer part number LCMXO2-640HC-4SG48C to the required package, voltage range, and temperature specification to avoid substitutions that alter footprint, electrical margin, or thermal limits.
