LCMXO640C-4B256C

The LCMXO640C-4B256C is a MachXO family field programmable gate array (FPGA) in a 256-ball LFBGA / CSPBGA package designed for single-chip, non-volatile logic integration. With 640 logic elements and up to 159 user I/Os, it targets glue logic, control logic and bus interfacing applications that benefit from instant-on behavior and in-field reconfiguration.

Built on the MachXO architecture, this device provides non-volatile configuration, fast startup and JTAG-programmable reconfiguration, enabling compact system designs that require secure, single-chip programmable logic. The device supports a wide supply range (1.71 V to 3.465 V) and commercial operating temperatures (0 °C to 85 °C).

Key Features

• Non-volatile, single-chip configuration – Instant-on operation with no external configuration memory required, delivering rapid power-up behavior.
• Reconfiguration support – Supports in-field reconfiguration and JTAG-based programming for fast updates and flexible system workflows.
• Logic capacity – 640 logic elements to implement glue logic, state machines and control functions within a compact FPGA fabric.
• I/O density – 159 user I/Os providing extensive interfacing options for buses, peripherals and board-level signals.
• Power and supply flexibility – Operates across a 1.71 V to 3.465 V supply range to accommodate multiple I/O standards and system rails.
• Package and mounting – Available in a 256-ball LFBGA / CSPBGA package (256-CABGA, 14×14 mm supplier package) for surface-mount assembly and high pin-count routing.
• Commercial grade temperature – Rated for operation from 0 °C to 85 °C for typical commercial applications.
• Standards and tools support – MachXO family devices support JTAG programming and are compatible with the ispLEVER design tools for synthesis, place-and-route and timing verification.
• RoHS compliant – Meets RoHS environmental requirements.

Typical Applications

• Glue Logic and System Control – Implement board-level control, reset sequencing and combinational glue logic with compact logic resources and fast startup.
• Bus Bridging and Interfacing – Provide flexible I/O and programmable interfacing for bridging between different bus standards or peripheral sets.
• Power-Up and Reset Control – Use non-volatile instant-on capability to manage power sequencing and deterministic startup behavior.
• Embedded Control and State Machines – Implement application-specific control logic and state machines where single-chip programmability and reconfiguration are advantageous.

Unique Advantages

• Instant-on, single-chip solution: Eliminates the need for external configuration memory, simplifying BOM and system startup.
• Field reconfiguration capability: JTAG-programmable and reconfigurable logic enables in-system updates and fast design iteration without hardware changes.
