LCMXO2-4000HC-4QN84C

The LCMXO2-4000HC-4QN84C is a MachXO2 family field-programmable gate array (FPGA) IC designed for commercial embedded applications that require flexible, reconfigurable logic and moderate I/O density. It provides 4,320 logic elements and approximately 94 kbits of on-chip RAM, making it suitable for control, interface bridging, and system glue logic.

Packaged in an 84-pin VFQFN (7 mm × 7 mm, exposed pad) for surface-mount assembly, this device supports a wide single-supply voltage range and RoHS compliance for commercial electronics designs.

Key Features

• Core Logic  4,320 logic elements provide flexible combinational and sequential logic resources for moderate-density designs.
• On-Chip Memory  Approximately 94 kbits of total on-chip RAM for small buffers, FIFOs or state storage.
• I/O and Voltage  68 I/O pins with a single-supply operating range from 2.375 V to 3.465 V, enabling compatibility with common commercial voltage domains.
• Family-Level Capabilities  As a MachXO2 device, the family includes features such as on-chip user flash memory, programmable I/O buffer options, and reconfiguration mechanisms for in-field updates (family-level specification: up to 256 kbits UFM and advanced I/O support).
• Clocking and Timing (Family)  MachXO2 family devices include flexible on-chip clocking with multiple primary clocks and support for PLLs (family-level description available in the MachXO2 datasheet).
• Package & Mounting  84-VFQFN dual-row package (84-QFN, 7×7 mm) with exposed pad, surface-mount compatible for compact PCB layouts.
• Temperature & Grade  Commercial-grade device with an operating temperature range of 0 °C to 85 °C.
• Compliance  RoHS compliant for environmentally restricted applications.

Typical Applications

• Embedded Control  Reconfigurable control logic and state machines for consumer and commercial embedded products where field updates and flexible control are required.
• Interface Bridging  Protocol translation and I/O aggregation between subsystems using the device’s I/O density and family-level programmable buffer support.
• System Glue Logic  Replace discrete glue components with a single reprogrammable device to simplify BOM and streamline PCB routing.
• Commercial Instrumentation  Implement custom timing, data buffering, and peripheral control functions in compact, surface-mount form factors.

Unique Advantages

• Right-sized Logic Density: 4,320 logic elements deliver measurable capability for moderate-complexity designs without excess resource cost or board area.
• Compact Package: 84-QFN (7×7 mm) with exposed pad supports dense board layouts and thermal management while maintaining surface-mount assembly compatibility.
• Flexible Power Integration: Wide single-supply voltage window (2.375 V to 3.465 V) simplifies power-rail design across common commercial systems.
• Reconfigurability: MachXO2 family reconfiguration features enable in-field updates and design iteration without hardware changes, reducing lifecycle costs.
• Commercial Temperature Range: Rated for 0 °C to 85 °C, matching typical commercial product operating requirements.
• Regulatory Compliance: RoHS compliance supports environmental requirements for commercial electronics manufacturing.
