LCMXO640C-5T100C

The LCMXO640C-5T100C is a MachXO family field programmable gate array (FPGA) in a 100-pin LQFP package optimized for glue logic, interfacing and system control applications. It delivers a non-volatile, reconfigurable core with 640 logic elements and 74 user I/Os, supporting compact, single-chip implementations where instant-on behavior and flexible I/O are required.

Designed for commercial-grade designs, the device combines MachXO family capabilities—single-chip non-volatile configuration, in-field reconfiguration and low-power modes—with a surface-mount 100-LQFP (14×14 mm) footprint, making it suitable for space- and cost-conscious embedded systems.

Key Features

• Reconfigurable non-volatile core – MachXO family architecture provides single-chip non-volatile configuration with instant-on behavior and no external configuration memory required.
• Logic capacity – 640 logic elements suitable for glue logic, bus bridging and control logic tasks.
• I/O – 74 general-purpose I/Os exposed in the 100-LQFP package to support a wide range of external interfaces.
• Voltage flexibility – Operates from 1.71 V to 3.465 V, enabling compatibility with multiple system voltage rails.
• Packaging and mounting – 100-LQFP (supplier package listed as 100-TQFP 14×14) in a surface-mount package for standard PCB assembly.
• Commercial temperature grade – Specified for 0 °C to 85 °C operation to match typical commercial embedded environments.
• Low-power and field update features – Family-level capabilities include sleep mode with substantial static current reduction and TransFR™ in-field reconfiguration for background updates while the system operates.
• Programmability and security – Supports JTAG-based programming and single-chip configuration for simplified deployment and improved bitstream security.
• Environmental compliance – RoHS compliant to meet current lead-free manufacturing requirements.

Typical Applications

• System Glue Logic – Replace discrete glue components with compact FPGA logic for bus interfacing, address decoding and control signal consolidation.
• Peripheral and Bus Bridging – Implement protocol adaptation and bridge functions between different voltage domains using the device’s flexible I/O and voltage range.
• Power-up and Control Sequencing – Use the instant-on, single-chip configuration to manage power sequencing and deterministic system bring-up.
• Embedded Control and State Machines – Implement compact control logic, user interfaces and finite-state machines leveraging 640 logic elements and abundant I/O.

Unique Advantages

• Single-chip, instant-on implementation: Eliminates external configuration memory and accelerates system start-up.
• Flexible I/O and voltage support: 74 I/Os and a wide supply voltage range simplify integration with multiple peripherals and power rails.
• Commercial-grade reliability: Specified 0 °C to 85 °C operation and surface-mount packaging for standard production environments.
• Field update capability: TransFR™ background reconfiguration enables in-field logic updates without halting system operation.
• RoHS compliance: Supports lead-free manufacturing processes and environmental requirements.
• Compact package: 100-LQFP (14×14 mm) reduces board area while providing ample I/O for mid-density designs.
