LCMXO640E-4BN256C

The LCMXO640E-4BN256C is a member of the MachXO family of non-volatile, reconfigurable FPGAs optimized for glue logic, bus bridging, power-up control and general control logic. This surface-mount 256-ball LFBGA (caBGA) device combines reconfigurable logic and flexible I/O in a compact 14×14 mm package for commercial-temperature applications.

Designed for instant-on operation and in-field updates, the device targets system-level integration where fast startup, design security and pin-efficient logic are priorities. Key hardware attributes include 640 logic elements, up to 159 I/Os, and a nominal supply voltage range of 1.14 V to 1.26 V.

Key Features

• Non-volatile, infinitely reconfigurable: MachXO family architecture supports instant-on operation and single-chip configuration without external configuration memory.
• Instant startup: Powers up in microseconds for rapid system availability.
• Logic density: 640 logic elements implemented across approximately 80 logic blocks, providing a mid-range resource set for glue logic and control functions.
• I/O capacity: 159 available I/Os in the 256-ball package to support dense board-level interfacing.
• Flexible I/O buffer support: Family-level programmable sysIO buffers support a wide range of interfaces, including LVCMOS, LVTTL, PCI, LVDS, Bus-LVDS, LVPECL and RSDS (as described for the MachXO family).
• Reconfiguration and field updates: TransFR™ Reconfiguration enables in-field logic updates while the system operates; non-volatile and SRAM-based logic can be reconfigured through standard programming interfaces.
• Power and thermal: Surface-mount 256-LFBGA (caBGA, 14×14 mm) package; commercial operating temperature range 0 °C to 85 °C and RoHS-compliant packaging.
• Supply voltage: Specified device supply range of 1.14 V to 1.26 V for core operation.
• On-chip RAM: Total on-chip RAM bits reported as 0 for this device variant.

Typical Applications

• Glue Logic and Board Orchestration: Implement address decoding, bus steering and signal conditioning between subsystems.
• Bus Bridging and Interfacing: Bridge between buses and handle protocol-adaptation tasks using available I/O and configurable buffers.
• Power-Up and System Control: Manage sequencing, reset distribution and startup control with instant-on behavior.
• Control Logic: Replace fixed CPLD functions with reconfigurable logic for feature updates and design migration.

Unique Advantages

• Single-chip non-volatile configuration: Eliminates the need for external configuration memory and simplifies BOM and board layout.
• Fast system availability: Microsecond power-up reduces system wait time and supports quick recovery after power events.
• High I/O to logic ratio: 159 I/Os with 640 logic elements enables dense interfacing for multi-signal control tasks without large FPGA overhead.
• In-field reconfiguration: Background programming and TransFR capabilities allow logic updates while preserving system operation.
• Compact, surface-mount package: 256-ball caBGA (14×14 mm) delivers a small footprint for space-constrained PCBs.
• Design tool support: MachXO family devices are supported by ispLEVER design tools and common synthesis flows for efficient implementation and timing verification.

Why Choose LCMXO640E-4BN256C?
