LCMXO2-640HC-4TG100I

Product Overview

LCMXO2-640HC-4TG100I is a Lattice Semiconductor Corporation MachXO2 field-programmable gate array for surface-mount designs. The device provides 640 logic elements or cells, 80 LABs or CLBs, 18,432 total RAM bits, and 78 input/output pins. It uses a 100-LQFP package, with a 100-TQFP (14 mm by 14 mm) body, and operates from a 2.375 V to 3.465 V supply. The junction temperature range is -40°C to 100°C.

Key Features

• 640 logic elements or cells and 80 LABs or CLBs provide configurable digital logic resources.
• 18,432 total RAM bits provide on-chip storage resources.
• 78 I/O pins are available for user-defined interfacing in a 100-LQFP surface-mount package.
• The supply voltage range is 2.375 V to 3.465 V.
• The operating junction temperature range is -40°C to 100°C.

Applications

• Custom control and sequencing logic in digital systems where flexible I/O mapping is required.
• Peripheral interfacing and glue-logic replacement using the available logic cells and on-chip RAM.
• Compact surface-mount FPGA implementations constrained by a 100-LQFP footprint and supply range.

Design & Procurement Notes

Designers should map required functions against the 640 logic elements or cells, 80 LABs or CLBs, 18,432 total RAM bits, and 78 I/O pins before committing to the package. The 100-LQFP or 100-TQFP (14 mm by 14 mm) footprint supports surface-mount assembly, while the 2.375 V to 3.465 V supply range and -40°C to 100°C junction temperature range should be reflected in power sequencing, thermal design, and board-level I/O planning. Because the device is a MachXO2 FPGA, configuration and resource utilization should be reviewed against the available logic and RAM capacity.
