LCMXO2-640UHC-4TG144I

The LCMXO2-640UHC-4TG144I is a MachXO2 family FPGA IC offering a mid-density, non-volatile programmable fabric suited for industrial designs. It provides 640 logic elements, 65,536 bits of on-chip RAM, and 107 general-purpose I/Os in a 144-pin LQFP/TQFP footprint.

With a single-supply operating range of 2.375 V to 3.465 V and an industrial operating temperature range of −40 °C to 100 °C, this device is positioned for control, glue-logic, and system-management functions where integration, low-power options and flexible I/O are important.

Key Features

• Logic Capacity — 640 logic elements for implementing mid-density combinational and sequential logic functions.
• Embedded Memory — 65,536 bits of on-chip RAM (approximately 64 kbits) for FIFOs, buffers and small data storage requirements.
• I/O Density and Flexibility — 107 I/Os in a 144-pin package to support a broad mix of peripheral and control interfaces.
• Voltage and Mounting — Single-supply operation from 2.375 V to 3.465 V; surface-mount package for PCB assembly.
• Industrial Temperature Grade — Specified for −40 °C to 100 °C operation for industrial-environment deployment.
• Non-volatile, Reconfigurable Architecture — MachXO2 family features include instant-on non-volatile logic with in-system programming via standard interfaces (JTAG, SPI, I2C) and background programming support.
• On-chip System Support (family-level) — Family data sheet describes integrated peripherals and system features such as on-chip user flash, SPI/I2C controllers, timers/counters and an on-chip oscillator to simplify system design.
• Package — 144-pin LQFP package case; supplier device package listed as 144-TQFP (20 × 20 mm) for compact board-level integration.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• Industrial Control — Implements glue logic, state machines and peripheral bridging for factory automation and machine control systems within the specified industrial temperature range.
• System Management — Provides in-field reconfigurable logic for power sequencing, system supervision, and real-time control tasks.
• Interface Bridging — Acts as a protocol/voltage translator and I/O expander where a mix of up to 107 I/Os and flexible I/O standards are required.
• Embedded Memory Functions — Uses on-chip RAM for small buffering, FIFO or temporary data storage needs in mid-density applications.

Unique Advantages

• Compact, Mid-Density Integration: 640 logic elements and 107 I/Os in a 144-pin package reduce board-level component count for moderate-complexity designs.
• Industrial-Grade Operation: Specified for −40 °C to 100 °C, enabling deployment in industrial environments.
• Flexible Power and I/O: Wide supply range (2.375 V–3.465 V) and family-level support for multiple I/O standards simplify mixed-voltage and mixed-protocol designs.
• Non-volatile, Reconfigurable: MachXO2 family features support instant-on, in-system programming and background programming to facilitate updates and field maintenance.
• On-chip Memory Resources: Approximately 65,536 bits of on-chip RAM support buffering and FIFO requirements without external memory in many mid-density use cases.
• Regulatory and Supply Assurances: RoHS compliance supports environmentally constrained product development and procurement requirements.
