LCMXO2-4000ZE-2QN84I

The LCMXO2-4000ZE-2QN84I is a MachXO2 family field programmable gate array (FPGA) IC from Lattice Semiconductor Corporation. It delivers 4320 logic elements and 68 I/O pins in a compact 84-VFQFN dual-row package with exposed pad, optimized for industrial-grade embedded applications.

Built for low-power, flexible system integration, this device combines reconfigurable logic, on-chip nonvolatile configuration and a wide range of programmable I/O capabilities to address interface, glue-logic and control functions in industrial systems.

Key Features

• Logic Capacity — 4320 logic elements provide mid-range programmable logic for control, glue and sequencing functions.
• Embedded Memory — Total on-chip RAM of 94,208 bits (reported) for distributed and block RAM usage in state machines, FIFOs and buffers.
• Flexible I/O — 68 I/Os with programmable sysIO buffer support; family-level I/O standards include LVCMOS (1.2–3.3 V), LVTTL, LVDS, Bus-LVDS, MLVDS, RSDS, LVPECL, PCI, SSTL and HSTL.
• Nonvolatile Configuration — MachXO2 family supports on-chip user flash and instant-on configuration, allowing single-chip, infinitely reconfigurable designs and background programming.
• Reconfiguration — TransFR™ in-field reconfiguration enables logic updates while the system is operating (family feature).
• Power Supply Range — Core voltage operation specified between 1.14 V and 1.26 V for this device.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C, suitable for industrial environments.
• Package and Mounting — Surface-mount 84-VFQFN dual-row package (supplier device package: 84-QFN, 7×7 mm) with exposed pad for thermal management.
• Low Power Family Traits — MachXO2 family highlights include ultra-low standby power and multiple power-saving modes (family-level feature).

Typical Applications

• Industrial Control — Use for control logic, sensor interfacing and I/O expansion where industrial temperature range and robust packaging are required.
• Interface Bridging & Glue Logic — Serve as protocol adapters and glue logic between disparate interfaces using the device’s programmable I/O standards and 68 I/Os.
• Display and Memory Interfaces — Implement source-synchronous and DDR/DDRx interfaces leveraging the MachXO2 family’s pre-engineered I/O and DDR support.
• Field-Upgradeable Systems — Enable in-field logic updates and background programming with TransFR reconfiguration and on-chip nonvolatile configuration.

Unique Advantages

• Integrated, Reconfigurable Platform: Single-chip nonvolatile configuration and TransFR in-field updates reduce the need for external configuration components and simplify firmware updates.
• Balanced Logic and I/O: 4320 logic elements combined with 68 configurable I/Os provide a practical balance for mid-density control and interfacing tasks.
• Industrial-Ready Thermal Range: Rated from −40 °C to 100 °C to meet the needs of industrial applications without additional derating.
• Compact, Thermally Managed Package: 84-VFQFN with exposed pad and 7×7 mm footprint supports compact board layouts while aiding thermal dissipation.
• Power-Focused Family Features: MachXO2 family-level low-power modes and standby options help minimize power consumption in always-on and battery-assisted systems.
• Rich I/O Compatibility: Programmable sysIO buffer family features support a wide range of signaling standards for flexible system integration.
