LCMXO256C-3TN100I

The LCMXO256C-3TN100I is a MachXO family FPGA optimized for glue logic, bus bridging, bus interfacing, power-up control and general control logic. It combines non-volatile, instant-on operation and flexible I/O in a single surface-mount 100‑pin LQFP package for compact, industrial-grade system designs.

Built around 256 logic elements and 32 logic blocks with up to 78 I/Os, this device delivers a compact, reconfigurable solution for systems that require fast startup, secure single-chip configuration and broad voltage support across industrial temperature ranges.

Key Features

• Core Logic  256 logic elements and 32 logic blocks provide the programmable fabric required for glue logic, control paths and small FPGA functions.
• I/O Density  Up to 78 I/Os enable broad peripheral and bus interfacing options in a single 100‑pin package.
• Non-volatile, Instant-on Configuration  Single-chip non-volatile configuration provides instant-on behavior and eliminates the need for external configuration memory.
• In-field Reconfiguration  Supports in-system reconfiguration and background programming mechanisms via JTAG and MachXO family TransFR reconfiguration features.
• Power and Voltage  Operates across a 1.71 V to 3.465 V supply range to accommodate mixed-voltage system designs.
• Package and Mounting  100‑pin LQFP (100‑TQFP, 14 × 14 mm) surface-mount package for through-board assembly in constrained footprints.
• Industrial Temperature Range  Rated for −40 °C to 100 °C operation, suitable for industrial applications.
• System-Level Support  Family-level features include JTAG boundary-scan, onboard oscillator and support for in-system programming workflows.
• Compliance  RoHS-compliant packaging for environmental compliance in manufacturing.

Typical Applications

• Glue Logic  Replace discrete gates and small CPLDs with a single programmable device for logic consolidation and BOM reduction.
• Bus Bridging and Interfacing  Implement protocol translation and buffering between legacy and modern buses using the device’s I/O density and reconfigurability.
• Power-Up and Reset Control  Instant-on configuration supports fast system boot and deterministic power sequencing and control logic.
• General Control Logic  Embedded control tasks, state machines and peripheral control can be implemented within the 256 logic elements and available I/Os.

Unique Advantages

• Instant-on, Single-chip Configuration: Eliminates external configuration memory and enables rapid system startup.
• Compact, Surface-mount Package: 100‑pin LQFP (14 × 14 mm) package reduces PCB area while providing high I/O count for dense board designs.
• Industrial Temperature Rating: −40 °C to 100 °C operation supports deployment in industrial environments.
• Flexible Voltage Support: Wide supply range (1.71 V to 3.465 V) allows integration into designs with mixed voltage domains.
• In-system Reconfigurability: JTAG and family-level background programming and TransFR capabilities allow updates and field changes without extra components.
• RoHS-compliant Packaging: Environmentally compliant packaging simplifies regulatory handling for production.
