LCMXO640E-3TN100C

The LCMXO640E-3TN100C is a MachXO family FPGA optimized for glue logic, bus interfacing, power-up control and general control tasks. The device combines non‑volatile, instant‑on operation and reconfigurable LUT-based logic to deliver fast system bring-up and secure single‑chip configuration without external memory.

Featuring 640 logic elements and up to 74 user I/Os in a compact 100‑pin LQFP/TQFP (14 × 14 mm) surface‑mount package, this commercial‑grade device targets embedded systems and high‑density I/O control where low latency, design security and easy in‑field updates are important.

Key Features

• Logic Capacity  Approximately 640 logic elements (LUTs) for implementing glue logic, state machines and interface bridging.
• I/O Density  74 programmable I/Os on the 100‑pin package provide extensive pin access for parallel buses and control signals.
• Non‑volatile, Instant‑On  Single‑chip, non‑volatile configuration enables microsecond power‑up and eliminates the need for external configuration memory.
• Reconfiguration  Supports in-field reconfiguration and background programming workflows for rapid updates and iterative development.
• Distributed Memory  MachXO family devices provide distributed RAM; the LCMXO640 device family lists approximately 6.1 Kbits of distributed RAM for small data buffers and state storage.
• Power  Operates from a primary core supply in the range of 1.14 V to 1.26 V, enabling integration with standard core rails.
• Package & Mounting  Available in a 100‑pin LQFP/TQFP (14 × 14 mm) surface‑mount package for easy PCB assembly and prototyping.
• Operating Range & Grade  Commercial grade with an operating temperature range of 0 °C to 85 °C and RoHS‑compliant packaging.
• Design Ecosystem  Supported by MachXO family design flows and tools for synthesis, place-and-route and timing verification.

Typical Applications

• Glue Logic & Control  Implement board-level control, resets, and power sequencing with compact, reconfigurable logic.
• Bus Bridging & Interfacing  Manage protocol translation and buffering between parallel and serial buses using abundant I/O and LUT resources.
• Peripheral and Sensor Aggregation  Consolidate multiple sensor inputs and peripheral control signals into a single programmable device.
• In-Field Updatable Systems  Enable field updates to control logic without removing the device from the system thanks to background and in-system reprogramming.

Unique Advantages

• Instant system availability: Non‑volatile single‑chip configuration provides immediate device operation on power‑up, shortening system boot time.
• Secure configuration model: No external configuration memory reduces attack surface for intercepted bitstreams and simplifies PCB design.
• High pin‑to‑logic ratio: 74 I/Os paired with 640 logic elements deliver strong I/O capability for dense interface and control applications.
• Compact, assembler‑friendly package: 100‑pin LQFP/TQFP (14 × 14 mm) simplifies prototyping and manufacturing on standard PCBs.
• Field‑update enabled: Background programming and reconfiguration support rapid iteration and deployed firmware updates.
• Toolchain support: Supported by MachXO family design tools for efficient synthesis, place‑and‑route and timing analysis.
