LCMXO640E-3FTN256I

The LCMXO640E-3FTN256I is a MachXO family Field Programmable Gate Array (FPGA) from Lattice Semiconductor, featuring 640 logic elements and up to 159 user I/Os in a 256-ball BGA package. Designed for glue logic, bus interfacing and control applications, this non-volatile, instant-on device delivers single-chip configurability with in-field reconfiguration and low-power modes suited to industrial systems.

Key Features

• Core Logic  640 logic elements provide flexible programmable logic capacity for control, glue logic and interface tasks.
• Memory  Distributed on-chip RAM capacity is available for small data buffering and state storage (family-level distributed RAM ~6.1 Kbits).
• I/O and Package  Up to 159 I/Os in a 256-ball package (supplier package: 256-FTBGA, 17×17 mm) for high pin-count requirements in compact footprints.
• Power Supply  Operates from a core supply range of 1.14 V to 1.26 V, enabling compatibility with standard low-voltage system rails.
• Thermal and Grade  Industrial-grade device rated for operation from -40 °C to 100 °C.
• Non-volatile, Instant-on Architecture  Single-chip non-volatile configuration enables microsecond power-up and removes the need for external configuration memory.
• Reconfiguration and Programming  Supports in-field reconfiguration (TransFR™) and background programming; JTAG-programmable SRAM and non-volatile memory for secure updates.
• Flexible I/O Buffering  Programmable sysIO buffers support multiple interface standards at the family level, including LVCMOS (1.2–3.3 V ranges listed at the family level), LVTTL, PCI, LVDS, Bus-LVDS, LVPECL and RSDS.
• System Support  Boundary-scan (IEEE 1149.1), onboard oscillator and IEEE 1532 in-system programming support simplify board bring-up and lifecycle updates.
• Low-Power Modes  Sleep mode capability enables significant static current reduction for power-sensitive systems (family-level sleep mode reduces static current by up to 100×).
• RoHS Compliant  Manufactured to meet RoHS environmental requirements.

Typical Applications

• Glue Logic and System Control  Implement power-up sequencing, reset generation and board-level control using compact programmable logic.
• Bus Bridging and Protocol Translation  Use the device’s I/O density and flexible buffers to bridge mismatched interfaces or implement protocol adapters.
• User Interface and Peripheral Control  Handle button scanning, LED control, and peripheral timing tasks with low-latency, deterministic logic.
• Industrial Automation  Industrial temperature rating and robust I/O count make the device suitable for control-plane logic and signal conditioning in industrial equipment.

Unique Advantages

• Single-chip, instant-on configuration: Eliminates external configuration memory and enables microsecond power-up for systems that require fast startup.
• Field-updatable logic: TransFR™ reconfiguration and JTAG-programmable non-volatile memory let you update logic in the field without removing the device.
• High I/O density in a compact package: 159 I/Os in a 256-ball BGA (17×17 mm supplier package) supports complex board-level interfacing with a small PCB footprint.
• Industrial operating range: Rated from -40 °C to 100 °C for deployment in temperature-challenging environments.
• Power-efficient operation: Sleep mode delivers substantial static current reduction for power-managed systems.
• Standards-based system support: Boundary-scan and IEEE 1532 in-system programming simplify manufacturing test and field maintenance.
