LCMXO640C-3TN144C

Product Overview

The LCMXO640C-3TN144C from Lattice Semiconductor Corporation is a MachXO field programmable gate array (FPGA) supplied in a 144-TQFP (20x20) surface-mount package. It provides 640 logic elements/cells across 80 LABs/CLBs and 113 user I/O, allowing designers to implement compact control, interfacing, and logic functions within a single device. The part operates from a 1.71 V to 3.465 V supply and is specified for a junction temperature range of 0°C to 85°C, making it suitable for board-level designs where the 144-TQFP (20x20) footprint and the available logic capacity are required.

Key Features

• MachXO FPGA architecture with 640 logic elements/cells and 80 LABs/CLBs for compact programmable logic functions.
• 113 user I/O for connecting external logic, sensors, controllers, and board-level interfaces.
• 1.71 V to 3.465 V supply voltage range.
• 0°C to 85°C operating junction temperature range.
• 144-TQFP (20x20) / 144-LQFP surface-mount package.

Applications

• Embedded control logic where multiple inputs, outputs, and state machines need to be integrated into one programmable device.
• Glue logic and interface bridging between board-level logic devices.
• Sensor and actuator interface logic in compact control boards.
• Custom timing and sequencing logic implemented within the FPGA.

Design & Procurement Notes

When selecting this device, confirm that the PCB land pattern matches the 144-TQFP (20x20) / 144-LQFP footprint and that the power rail can remain within 1.71 V to 3.465 V under all operating conditions. Evaluate the 80 LABs/CLBs, 640 logic elements/cells, and 113 I/O against the required logic and interface count, including space for user I/O connections. Because the specified operating range is 0°C to 85°C at the junction, account for self-heating and board thermal paths in dense designs. Use the surface-mount package as a constraint for assembly planning, and verify the final design against the 144-TQFP (20x20) package dimensions.
