LCMXO640C-4FTN256I

The LCMXO640C-4FTN256I is a MachXO-series Field Programmable Gate Array (FPGA) IC designed for compact, instant-on control and glue-logic applications. Built around a non-volatile MachXO architecture, this device provides reconfigurable logic resources and high pin-count I/O in a single surface-mount package.

Ideal for bus bridging, interface control, power-up sequencing and system glue logic, the device delivers a balance of integration, configurability and industrial-grade operation for embedded and control-oriented designs.

Key Features

• Non-volatile, instant-on configuration — Single-chip non-volatile architecture enables instant-on operation and eliminates the need for external configuration memory.
• Reconfigurable in-field — Supports background programming and in-field logic updates through TransFR reconfiguration and JTAG-programmable non-volatile memory.
• Core logic — 640 logic elements (LUTs) for implementing glue logic, control state machines and interface functions.
• Embedded memory — MachXO family characteristics include distributed RAM; the LCMXO640 family member provides approximately 6.1 Kbits of distributed RAM for small FIFOs and register storage.
• High I/O density — Up to 159 I/Os in the 256-ball package, enabling broad peripheral and bus interfacing capability.
• Flexible I/O standards — Family supports a wide range of I/O buffer standards for LVCMOS, LVTTL and differential interfaces, enabling routing and interface flexibility.
• Power and low-power modes — Wide operating supply range (1.71 V to 3.465 V) and sleep-mode capability for significant static current reduction.
• Clocking (family) — MachXO family supports sysCLOCK PLLs in some devices; per family data, the LCMXO640 device does not include analog PLLs.
• Package & mounting — Surface-mount 256-LBGA package (supplier package: 256-FTBGA, 17 × 17 mm) for compact board integration.
• Industrial temperature range — Rated for operation from −40 °C to 100 °C.
• Regulatory — RoHS compliant.

Typical Applications

• Glue Logic and Control — Implement system control, reset sequencing and glue logic to reduce discrete components and simplify PCB routing.
• Bus Bridging and Interface Conversion — Bridge or adapt between different bus standards and peripheral interfaces using plentiful I/O and programmable I/O buffers.
• Power-Up and Reset Management — Centralize power-up sequencing and supervisory control in a single non-volatile device for fast, deterministic start-up.
• Embedded System Control — Manage device orchestration, sensor interfaces and state machines where instant-on behavior and reconfigurability are valuable.

Unique Advantages

• Single-chip non-volatile solution: Eliminates external configuration memory, reducing BOM and simplifying board design.
• Instant-on operation: Powers up and resumes system control in microseconds, enabling fast system availability.
• High I/O-to-logic ratio: 159 I/Os paired with 640 logic elements make the device well suited for I/O-heavy control and interfacing tasks.
• Field reprogrammability: Background programming and TransFR enable safe in-field updates without pulling the device offline.
• Industrial robustness: Surface-mount 256-ball BGA in an industrial temperature grade supports deployment in demanding embedded environments.
• Wide supply compatibility: Operates across a broad supply range (1.71 V to 3.465 V), simplifying integration with diverse power rails.
