LCMXO640E-3FT256C

The LCMXO640E-3FT256C is a MachXO family FPGA offering a non-volatile, instant-on single-chip programmable logic solution. Built around an array of look-up table (LUT) logic elements and programmable I/O, it targets glue logic, bus interfacing and control applications that require fast start-up, in-field reconfiguration and flexible I/O support.

This device combines 640 logic elements, up to 159 I/O pins in a 256-ball BGA package, and support for background reconfiguration and sleep-mode current reduction — delivering integration, predictable supply requirements and commercial-grade operating range for embedded system designs.

Key Features

• Core Logic  640 logic elements (LUTs) arranged in the MachXO architecture for implementing glue logic, state machines and control functions.
• Non-volatile, Instant-On  Single-chip non-volatile configuration with instant-on behavior and no external configuration memory required.
• In-field Reconfiguration  Supports TransFR™ reconfiguration for in-field logic updates and background programming of non-volatile memory through the JTAG port.
• Low-power Options  Sleep mode provides up to 100× static current reduction for lower standby power.
• Flexible I/O  Up to 159 I/Os in the 256-ball package with programmable sysIO™ buffer support for multiple interface standards (as supported by MachXO family devices).
• Memory and Clock Support  MachXO family devices provide distributed RAM and up to two analog PLLs per device in the family; the LCMXO640 family member provides distributed RAM capacity and architecture-level PLL support where applicable.
• Power and Package  Operates with a VCC supply range of 1.14 V to 1.26 V. Supplied in a 256-LBGA / 256-FTBGA (17×17 mm) package, surface-mount mounting type.
• Commercial Temperature Grade  Specified for operation from 0 °C to 85 °C for commercial applications.
• Standards and Programming  Supports JTAG-based programming and system-level features typical of the MachXO family for in-system reprogramming and design security.

Typical Applications

• Glue Logic and System Glue  Implement interface bridging, address decoding and custom control logic to reduce external components and simplify board design.
• Bus Interfacing  Handle bus translation and buffering tasks with the device’s flexible I/O and reconfigurable logic to adapt to multiple standards.
• Power-Up and Reset Control  Use instant-on behavior and non-volatile configuration to implement power sequencing, reset control and supervisory logic that come up deterministically at system start.
• Control and State Machines  Implement deterministic finite-state machines, protocol handlers and peripheral control with the 640 logic elements and extensive I/O.

Unique Advantages

• Single-chip non-volatile implementation: Eliminates the need for external configuration memory, simplifying BOM and board layout.
• Instant-on behavior: Powers up in microseconds for systems that require immediate deterministic logic availability at boot.
• Field update capability: TransFR™ reconfiguration and JTAG-programmable non-volatile memory enable safe in-field logic updates and background programming.
• High pin-to-logic density: 159 I/Os paired with 640 logic elements provides a balance of I/O bandwidth and programmable logic capacity for interface-heavy designs.
• Low standby profile: Sleep mode reduces static current substantially for lower power in standby or low-activity states.
• Commercial-grade robustness: Specified 0 °C to 85 °C operation and surface-mount 256-ball BGA packaging suit a wide range of embedded and industrial-adjacent applications.
