LCMXO640E-4B256C

The LCMXO640E-4B256C is a MachXO family FPGA from Lattice Semiconductor that combines non-volatile, instant-on architecture with mid-range logic density. This surface-mount 256‑ball LFBGA device provides 640 logic elements and up to 159 I/Os in a 14×14 mm package, targeting glue logic, bus bridging, control and interface tasks in commercial designs.

Designed for compact system integration, the device supports single-chip configuration without external memory and operates across a core supply range of 1.14 V to 1.26 V within a commercial temperature range of 0 °C to 85 °C. The package is RoHS compliant for modern manufacturing environments.

Key Features

• Non‑volatile, single‑chip architecture — Instant-on operation and no external configuration memory required enable fast power-up and simplified BOM.
• Reconfiguration and background programming — Family-level MachXO features include background programming and in-field reconfiguration (TransFR) for live updates without full system downtime.
• Logic density — 640 logic elements provide capacity for glue logic, protocol bridging and mid‑complexity control tasks.
• I/O capacity and flexibility — Up to 159 I/Os in the 256‑LFBGA package allow high pin-to-pin connectivity for multi‑bus and multi‑interface applications.
• On‑device memory (family reference) — The MachXO family selection guide lists approximately 6.1 Kbits of distributed RAM for the LCMXO640 family; the family does not include embedded block SRAM for this density point.
• Power and sleep — Family features include sleep mode for significant static current reduction, helping lower standby power.
• Package and mounting — 256‑LFBGA (256‑cabga 14×14 mm) surface‑mount package suitable for compact PCB implementations.
• Commercial temperature and compliance — Rated for 0 °C to 85 °C operation and RoHS compliant.

Typical Applications

• Glue logic and system control — Implement power-up sequencing, reset control and board-level supervisory logic leveraging the non‑volatile, instant-on capability.
• Bus bridging and protocol interfacing — Use the device’s 159 I/Os and flexible routing for bus interfacing, level translation and protocol conversion tasks.
• Board-level subsystem integration — Replace discrete glue circuits with a single programmable device to reduce BOM and PCB area.
• Field-updatable control logic — In-system and background programming capabilities enable updates to control logic without external configuration memory.

Unique Advantages

• Single-chip configuration: Eliminates the need for external configuration memory, simplifying design and reducing component count.
• Instant-on availability: Rapid power-up behavior supports applications that require immediate logic availability after power is applied.
• High I/O-to-logic ratio: 159 I/Os alongside 640 logic elements enable dense interfacing for multi-signal designs without oversizing the logic fabric.
• Compact, production-ready packaging: The 256‑LFBGA surface-mount package is suited for space-constrained boards and standard manufacturing processes.
• Design flexibility and future-proofing: In-field reconfiguration and background programming let designs evolve post-deployment with minimal disruption.
