LCMXO640E-3TN144C

The LCMXO640E-3TN144C is a MachXO family FPGA from Lattice Semiconductor designed for glue logic, bus interfacing, control logic and related system tasks. It combines non-volatile configuration with a LUT-based logic architecture to deliver instant-on, reconfigurable logic in a single, surface-mount package.

With 640 logic elements distributed across 80 logic blocks and 113 I/Os in a 144-pin LQFP/TQFP footprint, this commercial-grade device targets compact, low-latency control and interfacing applications where single-chip configuration and rapid startup are important.

Key Features

• Logic Capacity — 640 logic elements organized across 80 logic blocks, enabling glue logic and small to medium-scale control functions.
• I/O Density — 113 user I/Os in a 144-pin package to support multi-interface designs and board-level signal routing.
• Non-volatile, Instant-on Configuration — MachXO family capability for single-chip configuration with no external configuration memory required and microsecond-range power-up behavior.
• Reconfiguration and Security — In-field reconfiguration and JTAG-programmable non-volatile and SRAM-based logic for secure updates and background programming.
• Embedded Memory (family data) — LCMXO640 family devices provide approximately 6.1 Kbits of distributed RAM for small data buffering and state storage (family-level specification).
• Supply Voltage — Operates from 1.14 V to 1.26 V, suitable for designs using low-voltage core rails.
• Package and Mounting — 144-pin LQFP/TQFP (20 × 20 mm) surface-mount package for compact PCB implementations.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operating temperature, RoHS compliant.
• Power Management Features — MachXO family supports sleep mode for significant static current reduction (family-level feature).

Typical Applications

• Glue Logic and Bus Interfacing — Implement address decoding, bus bridging and protocol translation in space-constrained systems.
• Power-up and Reset Control — Provide deterministic, instant-on control logic for power sequencing and system initialization.
• Peripheral and Sensor Interfaces — Aggregate and bridge multiple I/Os for sensor conditioning, GPIO expansion, and board-level signal management.
• Embedded Control and State Machines — Implement control state machines, monitoring logic, and small data buffers using distributed RAM.

Unique Advantages

• Single-Chip Non-Volatile Configuration: Eliminates the need for external configuration memory, simplifying BOM and board layout while enabling instant-on behavior.
• High Pin-to-Logic Ratio: 113 I/Os paired with 640 logic elements allow dense I/O interfaces alongside modest logic resources for efficient signal routing and control.
• Field Reconfigurability: Support for JTAG programming and in-field reconfiguration enables firmware updates and design iteration without hardware changes.
• Compact, Surface-Mount Package: 144-LQFP/TQFP (20 × 20 mm) package provides a balance of I/O count and PCB footprint for embedded applications.
• Commercial Temperature Rating with RoHS Compliance: Suitable for general-purpose electronics applications while meeting environmental compliance requirements.
• Design Tool Support (family-level): MachXO family is supported by Lattice design flows for synthesis, place-and-route, and timing verification.
