LCMXO256E-4MN100I

The LCMXO256E-4MN100I is a member of the MachXO family of non-volatile FPGAs. It integrates 256 logic elements with up to 78 general-purpose I/Os in a compact 100-ball LFBGA/CSPBGA package, optimized for control, interfacing and glue-logic roles in industrial systems. Key value propositions include instant-on non-volatile operation, single-chip configuration (no external configuration memory required), and operation across a wide industrial temperature range.

Key Features

• Core Logic  256 logic elements for implementing glue logic, control paths and bus interfacing.
• I/O Capacity  78 I/Os provided in a compact 100-LFBGA / 100-CSBGA (8×8) package, enabling dense pin connectivity for peripheral and bus interfaces.
• Non-volatile, Instant‑on  MachXO family non-volatile architecture delivers instant-on behavior and single‑chip configuration without external memory.
• In-field Reconfiguration (TransFR)  Supports in-field logic updates while the system operates, enabling firmware updates and design changes in deployed systems.
• Embedded & Distributed Memory (Family)  MachXO family devices provide embedded and distributed RAM resources; the family supports distributed RAM (LCMXO256 shows family-level support in datasheet information).
• Low-Voltage Operation  Device supply range is specified at 1.14 V to 1.26 V for the core supply.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C for industrial environments.
• Packaging & Mounting  Surface-mount 100-LFBGA / CSPBGA package (100-CSBGA 8×8) suitable for compact board designs.
• Standards & Compliance  RoHS compliant.

Typical Applications

• Glue Logic & System Control  Replace discrete logic with programmable, non‑volatile logic for power sequencing, reset control and board-level glue functions.
• Bus Bridging & Interface Conversion  Implement bus interconnects and protocol adaptation between peripherals, leveraging the device’s I/O density and flexible signaling.
• User Interface Control  Drive and manage keypads, displays and control panels where compact form factor and instant-on behavior are required.
• Peripheral Management  Centralize sensor multiplexing, GPIO expansion and device gating in industrial control applications.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory and enables fast system startup.
• Field-update capability: TransFR in-field reconfiguration allows logic updates without taking the entire system offline.
• Compact, high-pin package: 100-ball LFBGA/CSPBGA provides significant I/O in a small footprint for space-constrained designs.
• Industrial-rated operation: −40 °C to 100 °C range supports deployment in industrial environments.
• Low-voltage core: 1.14 V to 1.26 V supply supports modern low-voltage system architectures.
• RoHS compliant: Meets common regulatory requirements for lead‑free production.
