LCMXO640E-5B256C

The LCMXO640E-5B256C is a MachXO family FPGA optimized for glue logic, bus bridging, bus interfacing, power-up control and general control logic. It combines non-volatile configuration and FPGA-style LUT-based logic in a single, instant-on device with a compact 256-ball BGA package for space-constrained designs.

With 640 logic elements, up to 159 I/O and support for in-field reconfiguration and low-power modes, this commercial-grade device targets applications that need fast startup, flexible I/O and a high pin-to-logic density in a surface-mount package.

Key Features

• Core Logic 640 logic elements implemented across 80 configurable logic blocks (CLBs) for flexible combinational and sequential logic implementation.
• Non-volatile, Instant-on Configuration MachXO family architecture provides single-chip, non-volatile configuration with instant-on startup and in-field reconfiguration capabilities (background programming via JTAG).
• Memory Approximate 6.1 Kbits of distributed RAM available for small data buffering and LUT-based storage; no embedded block SRAM blocks on this device variant.
• I/O and Interface Flexibility Up to 159 I/Os in the 256-ball package, enabling high pin-to-logic connectivity for bus interfacing and signal routing.
• Power and Low-Power Modes Core voltage specified at 1.14 V to 1.26 V. Family-level features include a Sleep Mode that can achieve significant static current reduction.
• Package and Mounting 256-ball LFBGA / caBGA (14 × 14 mm) surface-mount package, RoHS compliant for modern assembly processes.
• Commercial Temperature Grade Rated for operation from 0 °C to 85 °C, suitable for commercial and many industrial-adjacent applications that do not require extended temperature ranges.
• System-Level Support MachXO family supports JTAG programming and in-system programming; designs for this family are supported by ispLEVER design tools as noted in the MachXO data sheet.

Typical Applications

• Glue Logic Implement board-level glue logic to replace discrete gate arrays and simplify PCB routing.
• Bus Bridging and Interfacing Provide flexible I/O mapping and protocol adaptation between subsystems with high pin density.
• Power-up and Control Sequencing Manage system power sequencing and supervisory control with instant-on behavior and on-chip configuration.
• General Control Logic Implement state machines, control paths and peripheral interfaces where single-chip non-volatile configuration and reconfigurability are advantageous.

Unique Advantages

• Single-chip non-volatile FPGA: Combines FPGA-style LUT logic with on-chip non-volatile configuration for instant-on systems without external configuration memory.
• High pin-to-logic density: 159 I/Os paired with 640 logic elements enable compact designs that require substantial I/O connectivity relative to logic capacity.
• In-field update capability: Supports background programming and JTAG-based reconfiguration for maintenance and feature updates without full system downtime.
• Low-power options: Sleep Mode from the MachXO family provides substantial static current reduction for power-sensitive applications.
• Compact BGA packaging: 256-ball 14 × 14 mm package supports surface-mount assembly and space-optimized board layouts.
• Design tool support: Family-level support by ispLEVER tools aids synthesis, place-and-route and timing verification workflows.
