LCMXO256E-3TN100C

The LCMXO256E-3TN100C is a MachXO family FPGA from Lattice Semiconductor designed for compact, non-volatile logic integration. This commercial-grade device combines an array of logic blocks and flexible I/O to address glue logic, bus bridging/interfacing, power-up control and general control logic in space-constrained systems.

With 256 logic elements across 32 logic blocks, up to 78 I/Os, and a 100-pin LQFP/TQFP package, the device targets designs that require instant-on configurability, moderate logic density, and a small footprint while operating within standard commercial temperature and supply ranges.

Key Features

• Core Logic 256 logic elements arranged across 32 logic blocks, enabling compact implementation of glue logic and control functions.
• On-chip Memory Approximately 2.0 Kbits of distributed RAM (family-level specification) for small data buffers and state storage; no embedded block RAM (EBR) in this device.
• I/O Capability Up to 78 general-purpose I/Os in the 100-pin package, providing broad connectivity for peripheral interfacing and bus bridging.
• Package 100-LQFP (supplier package listed as 100-TQFP, 14×14 mm) offering a compact, surface-mount footprint for PCB-constrained applications.
• Power Supply Core supply range specified at 1.14 V to 1.26 V for the device; I/O buffer standards are supported across the MachXO family (per family specification).
• Operating Grade and Temperature Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Non-volatile Family Characteristics MachXO family devices are described in the datasheet as single-chip, non-volatile devices with instant-on capability, in-field reconfiguration support, and sleep modes for reduced static current (family-level features).
• Standards and Compliance RoHS compliant per product data.

Typical Applications

• Glue Logic Implement address decoding, control signal multiplexing, and small combinational logic to reduce discrete gate count and PCB BOM.
• Bus Bridging and Interfacing Provide protocol adaptation, level translation, and pin-limited bus interfacing where a compact I/O-rich device is required.
• Power-Up and System Control Handle power sequencing, reset distribution, and startup state machines using the device’s instant-on and reconfiguration capabilities (family-level).
• Control Logic Replace small CPLD implementations with a single-chip FPGA for deterministic control and state management in embedded systems.

Unique Advantages

• Single-chip non-volatile solution: Family-level MachXO architecture provides instant-on operation and non-volatile configuration without external memory, simplifying system design.
• Compact, I/O-rich package: 78 I/Os in a 100-pin LQFP/TQFP footprint supports multiple peripheral interfaces while minimizing PCB area.
• Fine-grained logic for glue logic: 256 logic elements across 32 logic blocks make the device well-suited to replace discrete logic or CPLDs for moderate-density designs.
• Commercial temperature suitability: Rated for 0 °C to 85 °C, appropriate for standard commercial electronic products and equipment.
• Low-voltage core operation: Core supply specified at 1.14–1.26 V, enabling integration with modern low-voltage power domains.
• RoHS compliant: Meets lead-free, RoHS requirements to support regulated manufacturing processes.

Why Choose LCMXO256E-3TN100C?

The LCMXO256E-3TN100C positions itself as a compact, non-volatile FPGA option for designers who need instant-on configuration, a modest logic engine, and generous I/O in a small, commercial-grade package. It is suitable for applications where board space, quick startup behavior, and reduced BOM complexity are priorities.

When combined with the MachXO family design tools and the documented family-level features, this device offers a clear migration path for systems that may later require higher-density MachXO devices while maintaining the same development flow and design methodology.
