LCMXO2-4000HC-6QN84C

The LCMXO2-4000HC-6QN84C is a MachXO2 family FPGA from Lattice Semiconductor, offering a flexible logic architecture in a compact 84-VFQFN (7 × 7 mm) package. This commercial-grade, surface-mount device combines thousands of logic elements, embedded memory and programmable I/O to support control, glue-logic and interface tasks in space-constrained designs.

Designed for low-power operation and rapid start-up, the MachXO2 family architecture provides on-chip user flash memory, dedicated I/O features and system-level support functions to simplify integration and reduce BOM complexity.

Key Features

• Core Logic — 4320 logic elements provide programmable combinational and sequential resources for control, state machines and custom logic implementations.
• Embedded Memory — 94,208 bits of on-chip RAM (approximately 0.094 Mbits) to support buffers, FIFOs and small data storage requirements within the FPGA fabric.
• I/O Capacity & Flexibility — 68 user I/Os with programmable sysIO buffer options and support for a broad set of signaling standards, enabling a wide range of interface implementations.
• Non‑volatile Configuration — On-chip user flash memory and TransFR reconfiguration capabilities provide instant-on behavior and in-field logic update options.
• Clocking & PLLs — Family-level designs include multiple primary clocks and up to two analog PLLs for fractional‑n frequency synthesis and flexible clock management.
• Hardened System Functions — Integrated SPI, I2C and timer/counter blocks plus an on-chip oscillator help offload common system tasks from external components.
• Power & Voltage Range — Single-supply operation across 2.375 V to 3.465 V supports common system rails and enables straightforward power integration.
• Package & Thermal — 84-VFQFN dual rows with exposed pad in a 7 × 7 mm QFN form factor for surface-mount applications; commercial operating range from 0 °C to 85 °C.
• Compliance — RoHS compliant, supporting modern assembly and environmental requirements.

Typical Applications

• Interface Bridging and Glue Logic — Use the programmable logic and flexible I/O to consolidate protocol translation, bus interfacing and board-level glue functions.
• Display and Video I/O — Pre-engineered source-synchronous I/O and gearing options support display and high-speed parallel interfaces where precise timing is required.
• Embedded Control and State Machines — On-chip flash and integrated timers/counters enable compact control implementations for appliance and consumer electronics functions.
• Memory Buffering and FIFO Control — Available embedded RAM and dedicated FIFO control logic support temporary data buffering for streaming or burst transfers.

Unique Advantages

• Compact, Surface-Mount Package: 84-pin QFN (7 × 7 mm) with exposed pad reduces PCB footprint while providing thermal path for reliable operation.
• Integrated Non-volatile Memory: On-chip user flash enables instant-on capability and background programming without external configuration devices.
• Versatile I/O Standards: Programmable sysIO buffers and on-chip differential termination simplify multi-standard connectivity and reduce external components.
• System Function Integration: Built-in SPI, I2C, timers and oscillator cut down on discrete parts and streamline system design.
• Broad Voltage Range: Operation across 2.375 V to 3.465 V allows compatibility with common logic rails and simplifies power supply design.
