LCMXO640C-5TN100C

The LCMXO640C-5TN100C is a MachXO family non-volatile FPGA offered in a 100‑pin LQFP surface-mount package. It combines an array of logic CLBs and flexible programmable I/O to address glue logic, bus bridging/interfacing, power-up control and general control-logic roles in commercial electronic designs.

Designed for instant-on single-chip deployment, the device delivers 80 CLBs (640 logic elements) with approximately 6.1 Kbits of distributed RAM, 74 I/Os, and multi‑voltage I/O support—enabling compact, low‑component-count solutions across a range of 1.71 V to 3.465 V supply designs within a 0 °C to 85 °C operating range.

Key Features

• Non‑volatile, instant-on architecture Single-chip non‑volatile configuration for microsecond power-up and no external configuration memory required.
• Reconfiguration and in-field updates Supports in-field logic updates and background programming of non‑volatile memory for rapid design iteration and field upgrades.
• Low‑power operation and sleep mode Sleep mode enables significant static current reduction to conserve power in standby or low‑activity states.
• Logic array 80 CLBs delivering 640 logic elements for implementing glue logic, control finite-state machines, and interface logic.
• Embedded and distributed memory Approximately 6.1 Kbits of distributed RAM for small buffers, FIFOs, and register storage.
• Flexible programmable I/O 74 I/Os with sysIO buffer support for multiple signaling standards and a wide voltage range to interface with diverse peripherals.
• Package and mounting 100‑pin LQFP (14 × 14 mm) surface-mount package for easy PCB assembly and prototyping.
• Commercial grade and compliance Commercial temperature grade (0 °C to 85 °C) and RoHS compliant.

Typical Applications

• Glue Logic and System Glue Replace discrete logic with compact, reconfigurable CLBs to simplify PCB routing and reduce BOM.
• Bus Bridging and Protocol Conversion Implement bus interfacing and feature translation between legacy and modern subsystems using flexible I/O and programmable logic.
• Power‑Up and Reset Control Centralize power sequencing, reset control and supervisory logic with instant-on non‑volatile configuration.
• Control and User Interface Logic Implement finite-state machines, button/debouncing logic, LED control and simple UI controllers in a single device.

Unique Advantages

• Instant-on single-chip solution: Eliminates external configuration memory and delivers microsecond startup for faster system readiness.
• Field reprogrammability: In-field logic updates and background programming reduce service windows and enable post-deployment feature updates.
• Reduced system BOM: Integrated programmable I/O and distributed RAM reduce the need for discrete glue logic and peripheral components.
• Power savings: Sleep mode provides substantial static current reduction for energy-conscious designs.
• Design flexibility: 640 logic elements with 74 I/Os in a compact 100‑pin LQFP package fits space-constrained boards without sacrificing interfacing options.
• Regulatory readiness: RoHS compliance supports modern manufacturing and environmental requirements.
