LCMXO256E-3TN100I

The LCMXO256E-3TN100I is a MachXO family FPGA offering non-volatile, instant-on programmable logic in a 100-pin LQFP/TQFP package. Architected for glue logic, bus bridging/interfacing, power-up control and general control logic, it combines a compact pin count with a balance of I/O and logic density for industrial applications.

This device provides 256 logic elements and up to 78 user I/Os in a single-chip solution. It supports industrial operating conditions and a low-voltage core supply, delivering integration and predictable behavior for embedded and control designs.

Key Features

• Core Logic — 256 logic elements (LUT-based) organized into an array of logic blocks to implement control and glue logic functions.
• I/O Density — 78 I/Os available in the 100-pin package to support multiple peripheral and bus interfaces on compact PCBs.
• Non-volatile, Instant-On — MachXO family non-volatile architecture provides instant-on capability and single-chip configuration without external configuration memory.
• Reconfiguration and In-Field Updates — Supports background programming and TransFR™ in-field reconfiguration for updates while the system is operating.
• Low-Power Modes — Sleep mode can reduce static current by up to 100× for power-sensitive designs.
• Embedded Memory — Approximately 2.0 Kbits of distributed RAM (family selection for LCMXO256) for small data buffering and state storage; no embedded block RAM blocks are present for this density.
• Voltage and Temperature — Core supply range specified at 1.14 V to 1.26 V; industrial operating temperature range from −40 °C to 100 °C.
• Package — 100-pin LQFP (100-TQFP supplier package, 14 × 14 mm) for proven ease of assembly and prototyping.
• Standards & System Support — Family-level features include JTAG programming and IEEE 1149.1 boundary scan; the MachXO family supports background programming and programmable I/O buffers for multiple interface standards.
• RoHS Compliant — Device packaging and materials meet RoHS requirements.

Typical Applications

• Glue Logic — Consolidate discrete logic into a compact, reprogrammable device for board-level signal conditioning and simple state machines.
• Bus Bridging and Interfacing — Implement protocol adaptation and bus translation with up to 78 I/Os to route signals between subsystems.
• Power-Up and System Control — Manage sequencing, reset distribution and power control logic using non-volatile instant-on behavior.
• General Control Logic — Replace multiple CPLDs or small FPGAs in industrial control, instrumentation, and embedded systems.

Unique Advantages

• Single-Chip, No External Configuration Memory: Simplifies board design and reduces BOM by embedding configuration memory on-chip for instant-on operation.
• Reconfigurable In-Field: Background programming and TransFR reconfiguration let you update logic while the system remains operational, enabling field updates and iterative improvements.
• Industrial Temperature Range: Rated for −40 °C to 100 °C to meet the environmental demands of industrial implementations.
• High I/O for Low Density Logic: 78 I/Os paired with 256 logic elements provide a strong pin-to-logic ratio for interface-heavy designs.
• Low-Power Standby: Sleep mode capability enables large reductions in static current for energy-conscious systems.
• Proven Package Options: 100-pin LQFP/TQFP package supports easy prototyping and volume assembly on standard PCBs.
