LCMXO640E-4F256I

The LCMXO640E-4F256I is a MachXO family field programmable gate array (FPGA) in a 256-ball FPBGA (17×17 mm) package, designed for industrial applications. It combines instant-on, non-volatile configuration with a compact FPGA architecture that targets glue logic, bus bridging, system control, and I/O-intensive designs.

This device delivers 640 logic elements and up to 159 user I/Os in a surface-mount 256-BGA package, supporting reliable operation across an industrial temperature range and a tight core voltage window for predictable power budgeting.

Key Features

• Core Logic  640 logic elements provide programmable logic capacity suitable for glue logic, interface bridging, and control functions.
• I/O Density  159 user I/Os in the 256-FPBGA package enable high pin-to-logic ratios for board-level signal aggregation and bus interfacing.
• Non-volatile, Instant-on Configuration  MachXO family architecture supports single-chip non-volatile configuration for immediate start-up without external configuration memory.
• Reconfigurability and In-field Update  Family-level TransFR™ reconfiguration and background programming capabilities enable in-field logic updates while the system remains operational.
• Distributed Memory  Family documentation indicates distributed RAM on LCMXO640 devices (approximately 6.1 Kbits) for small FIFOs and buffering within designs.
• Low-power Modes  Sleep mode support can reduce static current substantially, aiding low-power standby and energy-sensitive applications.
• Flexible I/O Buffering  Programmable I/O buffers support a wide range of signaling standards (including various LVCMOS levels, LVTTL, LVDS variants and others) for interface flexibility.
• Packaging and Mounting  256-ball FPBGA (17×17 mm) surface-mount package for compact board integration with industrial-grade robustness.
• Industrial Temperature Range  Qualified for operation from −40 °C to 100 °C to meet typical industrial environment requirements.
• Supply Voltage  Core supply specified from 1.14 V to 1.26 V for predictable power design and decoupling requirements.
• Regulatory  RoHS-compliant packaging.

Typical Applications

• Glue Logic and System Control  Implement command sequencing, reset control, and simple state machines to consolidate discrete logic into a single programmable device.
• Bus Bridging and Protocol Conversion  Use the device’s I/O density to bridge between different bus standards or isolate legacy interfaces without large external logic assemblies.
• Sensor and Peripheral Interfacing  Aggregate signals from sensors and peripherals, providing deterministic control and buffering using on-chip logic and distributed RAM.
• Power-up and Sequencing Control  Leverage instant-on non-volatile configuration for reliable startup behavior and integrated control of power sequencing functions.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory and reduces system initialization complexity.
• High I/O-to-logic ratio: 159 I/Os paired with 640 logic elements supports dense interfacing without large-scale FPGA resources.
• Industrial-ready operation: Specified −40 °C to 100 °C and surface-mount 256-FPBGA packaging for robust deployment in industrial systems.
• In-field update capability: Family-level background programming and reconfiguration enable firmware updates with minimal system disruption.
• Power-conscious modes: Sleep mode support reduces static current for energy-efficient standby operation.
• Flexible I/O standards: Programmable I/O buffers support multiple signaling standards to simplify board-level interfacing.
