LCMXO640C-4TN144I

Product Overview

The LCMXO640C-4TN144I from Lattice Semiconductor Corporation is a MachXO family field programmable gate array (FPGA) for embedded logic functions. It integrates 640 logic elements and 80 LABs/CLBs, with 113 user I/O pins in a 144-LQFP surface-mount package. The device operates from a 1.71 V to 3.465 V supply and is specified for junction temperatures from -40°C to 100°C. This configuration supports board-level digital logic integration, peripheral interfacing, and reconfigurable control functions where a programmable logic device is needed.

Key Features

• MachXO family FPGA with 640 logic elements and 80 LABs/CLBs.
• 113 user I/O pins for board-level digital interfacing.
• 144-LQFP package (144-TQFP 20x20), surface mount.
• 1.71 V to 3.465 V supply voltage range.
• Operating temperature range of -40°C to 100°C (TJ).

Applications

• Embedded digital control logic in board-level systems.
• Interface and glue logic for multiple peripherals using the available I/O.
• Reconfigurable logic functions in development or production hardware.
• FPGA logic implementation within a 144-pin package.

Design & Procurement Notes

When selecting the LCMXO640C-4TN144I, check that the system power supply can operate within 1.71 V to 3.465 V and that the 144-TQFP (20x20) package fits the PCB and assembly constraints. The 113 I/O count should be compared against required peripheral connections, while the 640 logic elements and 80 LABs/CLBs provide the available programmable logic budget. Thermal design should account for junction temperature up to 100°C and operation down to -40°C. For embedded board-level designs, verify pin assignment, I/O requirements, and package density early, because these device parameters affect routing and layout.
