LCMXO640C-4FN256C

The LCMXO640C-4FN256C is a MachXO family field programmable gate array (FPGA) in a compact 256-BGA package. It provides a modest FPGA fabric with 640 logic elements and 80 configurable logic blocks (CLBs) combined with up to 159 general-purpose I/O to support flexible board-level integration.

Designed for commercial applications, this surface-mount FPGA supports a wide supply voltage range and a standard 0 °C to 85 °C operating temperature, offering a balance of integration and I/O density for space-constrained embedded systems and interface-centric designs.

Key Features

• Core Logic 640 logic elements implemented across 80 configurable logic blocks (CLBs) to implement glue logic, finite-state machines and small-scale digital functions.
• I/O Density Up to 159 device I/O pins suitable for multi-interface integration, peripheral expansion and signal routing on compact PCBs.
• Power Supply Range Operates from 1.71 V to 3.465 V, providing flexibility to interface with a variety of voltage domains on system boards.
• Package & Mounting 256-pin BGA in a 256-FPBGA (17×17) footprint with surface-mount mounting for automated assembly and compact system layouts.
• Operating Conditions Commercial-grade rating with an operating temperature range of 0 °C to 85 °C and RoHS-compliant materials.

Typical Applications

• Interface Bridging Use the device’s 159 I/O and configurable logic to consolidate and bridge multiple peripheral interfaces on a single board.
• Board-Level Glue Logic Implement custom control logic, address decoding and timing adjustments with the 640 logic elements and 80 CLBs.
• Compact Embedded Systems The 256-FPBGA (17×17) package and surface-mount design suit space-constrained modules requiring moderate programmable logic and I/O count.

Unique Advantages

• Compact, assembly-ready package: The 256-FPBGA (17×17) BGA reduces PCB footprint while supporting automated surface-mount assembly.
• High I/O capacity for the form factor: Up to 159 I/O pins allow integration of multiple peripherals without external multiplexers.
• Configurable logic for flexible designs: 640 logic elements across 80 CLBs provide the ability to implement custom control and interface functions on‑board.
• Wide supply compatibility: Support for 1.71 V to 3.465 V operation enables interfacing with common digital voltage domains.
• Commercial-grade reliability: Rated for 0 °C to 85 °C operation and RoHS compliant for standard commercial deployments.
