LCMXO640C-4MN100I

The LCMXO640C-4MN100I is a MachXO family FPGA offering non-volatile, instant-on programmable logic optimized for board-level control, glue logic and bus interfacing tasks. This industrial-grade device packages 640 logic elements across 80 logic blocks with 74 I/Os in a compact 100-ball CSP/LFBGA footprint.

Designed for applications requiring single-chip configuration and field reprogrammability, the device operates across a 1.71 V to 3.465 V supply range and an industrial temperature range of −40 °C to 100 °C, delivering flexibility for diverse embedded and control-system environments.

Key Features

• Core Logic — 640 logic elements implemented across 80 logic blocks (CLBs) to support glue logic, control sequencing and protocol bridging.
• Non-volatile, Instant-on — Single-chip non-volatile architecture enables instant-on operation and removes the need for external configuration memory.
• Reconfiguration and Field Updates — Supports in-field reconfiguration and background programming workflows for fast updates; SRAM-based logic reconfiguration in milliseconds.
• Memory — MachXO640 family provides distributed RAM resources consistent with the family architecture for small data buffering and state storage.
• I/O and Voltage Flexibility — 74 user I/Os and a supply range of 1.71 V to 3.465 V for interfacing to a variety of board-level voltage domains.
• Low-Power Modes — Sleep mode capability to substantially reduce static current for power-sensitive systems.
• Package and Mounting — Available in a 100-ball CSBGA / LFBGA (8×8 mm) package; surface-mount mounting for compact board implementations.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C for demanding environmental conditions.
• System-Level Support — Family-level support includes IEEE 1149.1 boundary scan and in-system programming features for design and manufacturing integration.
• RoHS Compliant — Meets RoHS requirements for lead-free manufacturing processes.

Typical Applications

• Glue Logic and Board Control — Implement glue logic, reset sequencing and power-up control to simplify discrete logic on mixed-signal and industrial PCBs.
• Bus Bridging and Protocol Conversion — Bridge between differing bus standards and perform protocol adaptation at the board level using flexible I/O resources.
• Interface and Peripheral Control — Act as a compact interface controller for sensors, displays, or peripheral subsystems requiring deterministic logic.
• Field Upgradeable Control Logic — Use background programming and in-field reconfiguration to deploy firmware updates to deployed systems with minimal downtime.

Unique Advantages

• Single-chip configuration: Eliminates external configuration memory and enables microsecond-scale power-up for faster system availability and lower BOM complexity.
• Compact, high-density I/O: 74 I/Os in a small 100-ball package reduce board area while enabling multiple interfaces and peripheral connections.
• Industrial-ready: Rated for −40 °C to 100 °C, supporting robust operation in industrial and harsh-environment applications.
• Flexible voltage operation: Broad supply range (1.71 V–3.465 V) eases integration with diverse power domains on modern boards.
• Field programmability: Background programming and in-system reconfiguration enable fast logic updates and iterative feature deployment without removing the device from the board.
• Manufacturing friendly: Surface-mount 100-ball CSBGA/LFBGA package and RoHS compliance simplify assembly and regulatory requirements.
