LCMXO640E-3T144I

The LCMXO640E-3T144I is a MachXO family FPGA that combines non-volatile, instant-on configuration with a compact surface-mount 144-pin package. With 640 logic elements and up to 113 I/Os in a 20 × 20 mm 144-pin TQFP/LQFP footprint, it targets control, glue-logic and I/O-intensive applications where fast startup, field reconfiguration and compact packaging are important.

Designed for industrial use, the device supports a broad operating temperature range and RoHS-compliant packaging, offering a reliable, single-chip programmable logic option for board-level control and interfacing tasks.

Key Features

• Core logic — 640 logic elements (LUTs) organized across 80 logic clusters, providing flexible combinational and sequential logic resources.
• I/O density — 113 user I/Os in the 144-pin package, enabling extensive peripheral and bus connectivity in a compact form factor.
• Non-volatile, instant-on configuration — MachXO family architecture offers single-chip, non-volatile configuration for microsecond power-up and no external configuration memory requirement.
• In-field reconfiguration — Supports background programming and TransFR reconfiguration for updates while the system is operating (family-level capability).
• Power and supply — Core supply specified at 1.14 V to 1.26 V to match system voltage requirements.
• Package & mounting — 144-pin LQFP/TQFP surface-mount package (supplier: 144-TQFP, 20 × 20 mm), suitable for compact PCB layouts.
• Industrial grade temperature — Rated for operation from −40 °C to 100 °C for industrial environments.
• Regulatory compliance — RoHS compliant.

Typical Applications

• Glue Logic & System Control — Implement power-up sequencing, reset control, and board-level control logic with instant-on behavior.
• Bus Bridging and Interfacing — Use the high I/O count to implement bus adapters, protocol translators and interface glue between subsystems.
• Peripheral and I/O Expansion — Add custom I/O handling, signal conditioning logic and interface glue in a compact package.
• Field-Upgradeable Logic — Enable in-field updates and background programming to evolve system functionality without hardware replacement.

Unique Advantages

• Single-chip, non-volatile solution: Eliminates the need for external configuration memory and enables microsecond-class power-up for faster system availability.
• High I/O-to-logic ratio: 113 I/Os paired with 640 logic elements supports dense interfacing and flexible logic implementation on the same device.
• Compact surface-mount package: 144-pin LQFP/TQFP (20 × 20 mm) delivers significant integration while fitting space-constrained PCB designs.
• Industrial temperature operation: −40 °C to 100 °C rating makes the device suitable for demanding embedded and industrial environments.
• Reconfigurability in the field: Background programming and TransFR capabilities (family-level) reduce maintenance time and extend product lifetime through firmware updates.
• RoHS-compliant packaging: Meets common environmental and manufacturing requirements for modern assemblies.
