LCMXO2-640UHC-5TG144C

Product Overview

The Lattice Semiconductor Corporation LCMXO2-640UHC-5TG144C is a MachXO2 field programmable gate array for embedded digital logic implementation. It provides 640 logic elements, 80 LABs or CLBs, and 65,536 total RAM bits, with 107 I/O pins. The device uses a 144-LQFP surface-mount package, identified as 144-TQFP (20 x 20 mm). Its supply voltage range is 2.375 V to 3.465 V, and its operating temperature range is 0 °C to 85 °C at the junction.

Key Features

• 640 logic elements and 80 LABs or CLBs for custom digital logic.
• 65,536 total RAM bits for on-chip data storage and buffering.
• 107 I/O pins for peripheral connection and board-level signal routing.
• 2.375 V to 3.465 V supply voltage range.
• 144-LQFP surface-mount package, 144-TQFP (20 x 20 mm) form.
• 0 °C to 85 °C junction operating temperature.

Applications

• Embedded control logic where custom state machines, sequencing, or glue logic replace discrete components.
• Peripheral interfacing for sensors, actuators, displays, or other I/O devices.
• Protocol bridging and signal conversion between digital subsystems.
• Small data buffering or temporary storage within an embedded system.

Design & Procurement Notes

Design teams should verify that the board power rail remains within the 2.375 V to 3.465 V supply range and that thermal conditions keep the junction temperature between 0 °C and 85 °C. The 144-TQFP (20 x 20 mm) surface-mount package requires footprint, stencil, and reflow planning for the 144-LQFP form. The available 640 logic elements, 80 LABs or CLBs, 65,536 RAM bits, and 107 I/O pins define the upper limit of logic, memory, and interface resources for the selected device. These values should be checked against the planned logic blocks, on-chip buffering, and external signal count before finalizing the architecture.
