LCMXO640C-3TN144I

The LCMXO640C-3TN144I is a MachXO family FPGA device offering non-volatile, instant-on programmable logic in a 144-pin surface-mount package. Built for glue logic, bus bridging, power-up control and control logic use cases, it combines reconfigurable LUT-based logic with flexible I/O and industrial temperature capability to address a broad range of embedded system requirements.

As a member of the MachXO series, this device emphasizes single-chip integration (no external configuration memory), fast start-up and field reprogramming while providing a compact 144-LQFP footprint and up to 113 general-purpose I/Os.

Key Features

• Core Logic — 640 logic elements (LUT-based) suitable for glue logic and control functions.
• Embedded Memory — Approximately 6.1 Kbits of distributed RAM and no embedded block RAM, matching the LCMXO640 family memory profile.
• Reconfiguration & Security — MachXO family capabilities include non-volatile, instant-on operation and single-chip configuration (no external configuration memory required), plus in-field reconfiguration options via JTAG and background programming.
• Low-Power Modes — Sleep mode support for significant static current reduction during low-activity periods.
• I/O & Package — Up to 113 I/Os in a 144-pin surface-mount package (144-LQFP / 144-TQFP 20×20 mm) to simplify board-level integration.
• Supply & Temperature — Operates from 1.71 V to 3.465 V and rated for industrial operating temperatures from −40 °C to 100 °C.
• Programmable I/O Standards — Family sysIO buffer support for a broad set of interfaces including multiple LVCMOS voltage levels, LVTTL and differential IO standards as provided by the MachXO family architecture.
• System Support — Family-level support for IEEE 1149.1 boundary scan and in-system programming workflows; supported by MachXO family design tools referenced in the datasheet.
• Compliance — RoHS-compliant packaging.

Typical Applications

• Glue Logic / Board-Level Control — Implement combinational and simple sequential logic to replace discrete gates and reduce BOM count.
• Bus Bridging & Interface Logic — Create custom bus adapters, level translation and signal routing using the device’s flexible I/O and reprogrammable logic.
• Power-Up & System Sequencing — Manage power sequencing, reset control and supervisory functions with instant-on behavior and single-chip configuration.
• Industrial Control — Deploy in industrial environments that require operation across −40 °C to 100 °C and robust surface-mount packaging.

Unique Advantages

• Single-Chip, Instant-On: Non-volatile configuration eliminates the need for external configuration memory and enables fast power-up behavior.
• Field Reprogrammability: Background programming and JTAG-based updates allow in-field logic changes without removing the device.
• Flexible I/O in Compact Package: Up to 113 I/Os in a 144-LQFP package provides high pin-to-pin connectivity in a standard surface-mount form factor.
• Industrial Temperature Rating: Rated from −40 °C to 100 °C for use in temperature-challenging environments.
• Low-Power Operation: Sleep mode support reduces static current for power-sensitive designs.
• Design Ecosystem: MachXO family devices are supported by the vendor’s design tools referenced in the product datasheet for implementation and timing verification.
