LCMXO2-640UHC-5TG144I

The LCMXO2-640UHC-5TG144I is a MachXO2 family FPGA offering a compact, non-volatile logic solution with 640 logic elements and 107 I/Os in a 144-lead LQFP package. It combines flexible programmable logic, embedded memory, and advanced I/O features to address interface bridging, system control, and low-power instant-on requirements in industrial applications.

Key Features

• Logic Capacity — 640 logic elements (cells) provide the programmable fabric for glue logic, control tasks, and small to mid-size custom logic functions.
• On-chip Memory — Total on-chip RAM of 65,536 bits (approximately 64 kbits) supports local buffering, small FIFOs, and distributed memory needs.
• I/O Density & Flexibility — 107 user I/Os in a 144-LQFP package; programmable sysIO buffers enable a wide range of signaling standards as documented for the MachXO2 family.
• Power Supply Range — Operates from 2.375 V to 3.465 V, supporting designs that require flexible supply rail options.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C to meet industrial environment requirements.
• Non-volatile, Instant-on Architecture — MachXO2 family features include single-chip non-volatile configuration and fast power-up behavior for systems requiring immediate availability.
• Reconfiguration & System Functions — Family-level capabilities include in-field reconfiguration (TransFR), on-chip peripherals such as SPI and I²C, and hardened timer/counter resources to simplify system integration.
• Package & Mounting — 144-lead LQFP (surface-mount) footprint (20 mm × 20 mm supplier TQFP outline), suitable for PCB assembly processes where a low-profile SMD package is required.
• Regulatory & Reliability — RoHS-compliant construction and specified industrial grade operating range for deployment in commercial and industrial systems.

Typical Applications

• Interface Bridging and Glue Logic — Use the programmable fabric and abundant I/Os to implement protocol bridges, bus adapters, and custom timing logic between subsystems.
• Embedded System Control — Implement control state machines, I/O supervision, and system housekeeping functions leveraging on-chip memory and peripheral interfaces.
• Display and Memory Interfaces — Pre-engineered I/O and DDR/gearable I/O capabilities in the family simplify display driving and external memory interfacing tasks.
• Low-power Standby Systems — Family-level low standby power features and instant-on behavior make this device suitable for systems requiring minimal idle power and fast wake-up.

Unique Advantages

• Compact, Non-volatile FPGA: Single-chip non-volatile configuration eliminates the need for external configuration PROM and delivers instant-on capability.
• Balanced Logic and I/O: 640 logic elements paired with 107 I/Os in a 144-LQFP package offers a practical balance for many industrial control and interface tasks without excessive board area.
• Industrial Temperature Rating: Specified operation from −40 °C to 100 °C supports deployment in harsh or temperature-variable environments.
• Flexible Power Options: Wide supply range (2.375 V to 3.465 V) enables integration into systems with varying voltage rails.
• System Integration Features: On-chip peripherals (SPI, I²C, timers) and in-field reconfiguration capability reduce BOM and simplify firmware and hardware updates in the field.
