LCMXO640E-5MN100C

The LCMXO640E-5MN100C is a MachXO family field-programmable gate array (FPGA) optimized for glue logic, bus interfacing, power-up control and general control applications. It combines a grid of configurable logic blocks with flexible programmable I/O in a single, non-volatile device that powers up instantly and requires no external configuration memory.

This surface-mount 100-LFBGA/CSPBGA part offers 640 logic elements (80 logic blocks) and 74 user I/Os in a compact 100-ball package, making it suitable for space-constrained system designs that need fast boot, secure configuration and in-field reconfiguration support.

Key Features

• Core Logic  640 logic elements implemented across 80 logic blocks for implementing glue logic, control paths and small to medium control fabrics.
• Non-volatile Configuration  Instant-on single-chip configuration with no external configuration memory required; supports programming via JTAG and background programming of non-volatile memory.
• In-field Reconfiguration (TransFR)  Supports TransFR reconfiguration for updating SRAM-based logic while the system is operating.
• Low-power Operation  Sleep mode support to reduce static current by up to 100× for lower standby power.
• I/O and Package  74 I/Os in a 100-LFBGA / 100-CSBGA (8×8 mm) package; surface-mount mounting type for compact board-level integration.
• Flexible I/O Buffer Options  Family I/O buffer support for a wide range of standards and interface types, enabling diverse system interfacing (as described in the MachXO family documentation).
• Voltage and Temperature  Operates from 1.14 V to 1.26 V supply and is specified for commercial-grade operation from 0 °C to 85 °C.
• On-chip Memory  Product specification lists total on-chip RAM as 0 bits for this device.
• PLLs  The MachXO640 device does not include analog PLLs (refer to MachXO family documentation for PLL availability across other family members).
• Compliance  RoHS-compliant packaging.

Typical Applications

• Glue Logic and Board-Level Control  Implement address decoding, bus arbitration and small control state machines without external configuration storage.
• Bus Bridging and Interfacing  Bridge between subsystems and implement bus-interface logic using the device’s flexible I/O and compact footprint.
• Power-Up and Reset Control  Manage system power sequencing and reset logic with instant-on behavior for rapid system availability.
• Embedded Control Logic  Replace discrete glue and control ICs with a single programmable device to reduce board complexity and BOM.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory, shortening boot time and simplifying BOM.
• Secure configuration model: No external bitstream required at power-up, reducing the risk of configuration interception.
• Compact BGA package: 100-ball LFBGA/CSPBGA footprint delivers 74 I/Os and 640 logic elements in an 8×8 mm package for tight board layouts.
• In-field reconfiguration: TransFR support enables logic updates while the system is running, improving field maintainability.
• Low standby power: Sleep mode provides substantial static current reduction for power-sensitive designs.
• Toolchain support: Supported by the MachXO family design flows described in the MachXO family documentation for synthesis, place-and-route and timing analysis.
