LCMXO640E-4TN100I

The LCMXO640E-4TN100I is a MachXO family FPGA providing non-volatile, instant-on programmable logic in a compact 100-pin package. It integrates 640 logic elements and 74 user I/Os in a single surface-mount device targeted for glue logic, bus bridging, power-up control and general control-logic roles.

Designed for industrial environments, the device combines single-chip non-volatile configuration, fast reconfiguration of SRAM-based logic, and flexible I/O options to simplify system design and reduce external BOM requirements.

Key Features

• Non-volatile single-chip architecture – Instant-on operation with no external configuration memory required, improving boot behavior and system security.
• Reconfigurable logic – 640 logic elements support SRAM-based logic that can be reconfigured in milliseconds and programmed via JTAG or background programming.
• In-field updates (TransFR) – TransFR reconfiguration supports in-field logic updates while the system continues to operate.
• Low-power modes – Sleep mode enables substantial static current reduction for power-sensitive applications.
• Flexible I/O – 74 I/Os with programmable sysIO buffer support a wide range of interfaces referenced by the MachXO family, enabling easy signal-level adaptation and bus interfacing.
• Memory options (family reference) – MachXO family devices provide embedded and distributed memory options; the family data sheet lists distributed RAM for the LCMXO640 series.
• Industrial operating range – Engineered for industrial use with an operating temperature range of −40°C to 100°C and RoHS-compliant packaging.
• Package and mounting – Available in a 100-pin LQFP surface-mount package (100-TQFP, 14 × 14 mm footprint) for compact PCB designs.
• Supply voltage – Operates within a supply range of 1.14 V to 1.26 V as specified for this product variant.

Typical Applications

• Glue Logic and System Control – Implement board-level interconnect, address decoding, and power sequencing without external configuration memory.
• Bus Bridging and Interfacing – Handle protocol translation and bus interfacing with flexible I/O and programmable buffers.
• Power-up and Reset Management – Manage power sequencing, reset distribution, and supervisory control using non-volatile instant-on logic.
• Embedded Control Logic – Replace discrete state machines and small microcontroller tasks with compact programmable logic to reduce BOM and simplify layouts.

Unique Advantages

• Single-chip configuration: Eliminates external configuration memory for simpler hardware and faster system start-up.
• Fast in-field updates: TransFR reconfiguration enables updates to logic while the system is running, reducing downtime for firmware/logic revisions.
• Industrial reliability: −40°C to 100°C operating range and surface-mount 100-pin packaging support robust deployment in industrial environments.
• Reduced BOM and board area: Integrated I/O, non-volatile configuration, and reconfigurable logic consolidate multiple discrete components into one device.
• Flexible interfacing: Programmable I/O buffering lets the device adapt to various signaling standards and bus requirements documented for the MachXO family.
