LCMXO256C-5T100C

The LCMXO256C-5T100C from Lattice Semiconductor Corporation is a MachXO family FPGA optimized for glue logic, bus bridging, power-up control and system control functions. This surface-mount device delivers non-volatile, instant-on FPGA capability in a compact 100-pin LQFP package while providing 78 user I/Os and 256 logic elements for low-to-moderate density control and interfacing tasks.

Designed for commercial-grade applications, the device supports flexible supply voltages and fast in-field reconfiguration options characteristic of the MachXO family, making it suitable for embedded system designers who need single-chip configuration and fast startup behavior.

Key Features

• Non-volatile, instant-on architecture – Single-chip configuration with no external configuration memory required; instant-on behavior is a MachXO family characteristic for rapid system startup.
• Logic capacity – 256 logic elements organized across 32 logic blocks, suitable for glue logic, state machines and control functions.
• I/O density and flexibility – 78 user I/Os in the 100-LQFP package to support a variety of interfaces and board-level signal routing.
• Voltage range – Operates across a wide supply range (1.71 V to 3.465 V), enabling compatibility with multiple system power rails.
• Programmability and in-field updates – Supports background and in-field reconfiguration of SRAM-based logic as described for the MachXO family, enabling fast updates and design flexibility.
• Low-power mode – Sleep mode capability (MachXO family feature) that reduces static current for lower power standby operation.
• Package and mounting – 100-pin LQFP surface-mount package (supplier device package: 100-TQFP, 14×14 mm) for easy placement in space-constrained designs.
• Commercial temperature grade – Rated for 0 °C to 85 °C operating temperature, suitable for general-purpose commercial applications.
• RoHS compliant – Device meets RoHS requirements for lead-free packaging and manufacturing.

Typical Applications

• Glue Logic and System Control – Implement board-level glue logic, power-up sequencing and control state machines using the device’s logic resources and instant-on behavior.
• Bus Bridging and Interfacing – Use the 78 I/Os to bridge buses, translate signal standards and implement protocol adaptation in compact systems.
• Peripheral and User-Interface Control – Manage button scanning, LED drivers, and peripheral control logic without external configuration memory.
• In-field Feature Updates – Apply background or in-field reconfiguration to update control logic or add features while the system remains in operation.

Unique Advantages

• Single-chip configuration: Eliminates the need for external configuration memory, reducing BOM and simplifying system design.
• Fast startup: Instant-on capability from the MachXO family enables quicker system readiness compared with solutions requiring external configuration.
• Flexible I/O and supply support: 78 I/Os and a broad supply voltage window (1.71 V–3.465 V) simplify integration with mixed-voltage systems.
• Compact package: 100-LQFP (14×14 mm) package offers a small footprint for space-constrained PCBs while retaining substantial I/O count.
• Power management options: Sleep mode reduces static current for lower standby power in battery-powered or energy-conscious applications.
• Commercial-grade reliability: 0 °C to 85 °C operating range and RoHS-compliant packaging align with general-purpose commercial product requirements.
