LCMXO2-640HC-4TG100I

The LCMXO2-640HC-4TG100I is an industrial-grade MachXO2 FPGA in a 100-pin LQFP package optimized for low-power, instant-on control and glue-logic applications. Built on the MachXO2 family architecture, it combines a compact logic fabric with embedded RAM and configurable I/O to address control, interface bridging, and system integration tasks in industrial and embedded systems.

Key value propositions include a defined set of 640 logic elements, 78 programmable I/Os, and a single-supply voltage range that supports flexible integration into 2.375 V–3.465 V systems while operating across an extended -40 °C to 100 °C temperature range.

Key Features

• Core Logic: 640 logic elements provided for combinational and sequential logic implementation suitable for glue logic, peripheral control, and simple state machines.
• Embedded Memory: Total on-chip RAM of 18,432 bits for small FIFOs, buffers, and lookup tables required by control and interface functions.
• Flexible I/O: 78 programmable I/O pins with support for a wide range of interfaces described in the MachXO2 family, enabling serial/parallel interconnects and mixed-signal interfacing.
• On-Chip Non-Volatile Memory: Family-level MachXO2 capability for on-chip user flash memory and background programming for configuration and firmware storage.
• Power and Supply: Single-supply operation across 2.375 V to 3.465 V and family-level low-power design options for standby and power saving modes.
• Package & Mounting: 100-LQFP (100-pin TQFP, 14 mm × 14 mm) surface-mount package suitable for compact, board-level integration.
• Industrial Temperature Range: Rated for operation from -40 °C to 100 °C, supporting deployment in industrial and harsh-environment applications.
• Regulatory Compliance: RoHS compliant, meeting common environmental requirements for electronic assemblies.

Typical Applications

• Industrial Control: Implement custom control logic, sensor interfacing, and supervisory functions where industrial temperature range and compact packaging are required.
• Interface Bridging: Bridge peripherals and buses with programmable I/O to adapt legacy or mixed-voltage interfaces in embedded systems.
• User Interface Control: Drive and manage human‑machine interface elements such as keypads, LEDs, and simple displays using embedded logic and RAM.
• System Glue Logic: Consolidate discrete glue functions, address decoding, and simple protocol conversion to reduce BOM and PCB complexity.

Unique Advantages

• Compact, Deterministic Logic: 640 logic elements provide a predictable, fixed resource set for rapid implementation of control and glue applications.
• Embedded RAM for Buffers: 18,432 bits of on-chip RAM support small FIFOs and buffering without external memory.
• Flexible I/O Count and Standards: 78 I/Os give design flexibility for mixed-signal interfacing and peripheral expansion on a single chip.
• Industrial Reliability: Operation from -40 °C to 100 °C and RoHS compliance align the device with industrial deployment requirements.
• Single-Supply Integration: Broad voltage supply range (2.375 V–3.465 V) simplifies power-rail planning in diverse embedded systems.
• Small-Footprint Packaging: 100-LQFP surface-mount package offers a balance of pin count and board area for compact designs.
