LCMXO256C-4T100C

The LCMXO256C-4T100C is a MachXO family FPGA optimized for glue logic, bus interfacing and control applications. It combines a non-volatile, instant-on architecture with a compact 100-pin LQFP package for space-conscious designs.

This device provides 256 logic elements and up to 78 programmable I/Os in a surface-mount 100-pin package, and operates across a broad supply range of 1.71 V to 3.465 V for flexible system integration.

Key Features

• Core Logic  256 logic elements provide the configurable fabric for implementing glue logic, state machines and custom control functions.
• I/O Density  Up to 78 I/Os suitable for interfacing with peripherals, buses and external logic in compact systems.
• Non-volatile Instant-On Architecture  MachXO family features include single-chip, non-volatile configuration and instant-on startup behavior for rapid system availability without external configuration memory.
• Reconfiguration & Security  Family-level support for in-field reconfiguration and secure configuration (no separate bitstream to intercept) enables updates and design protection.
• Low-Power Modes  MachXO family sleep mode capability provides significant static current reduction for power-sensitive applications.
• Package & Mounting  100-pin LQFP (supplier device package: 100-TQFP 14×14 mm), surface-mount construction for standard PCB assembly flows.
• Voltage & Temperature  Supply range 1.71 V to 3.465 V; commercial operating temperature 0 °C to 85 °C.
• Environmental  RoHS compliant packaging.

Typical Applications

• Glue Logic and Glue Functions  Implement glue logic and small-scale combinational and sequential functions to simplify board-level BOM and reduce external components.
• Bus Bridging and Interfacing  Act as a bridge or translator between different bus standards and I/O families using available I/O resources.
• Power-Up and System Control  Control power sequencing, reset distribution and supervisory functions that require reliable, deterministic behavior at startup.
• Control and State Machines  Replace discrete logic or CPLDs for compact control logic, finite state machines and coordination tasks in embedded systems.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory and enables rapid system startup.
• Compact, high-pin-to-logic ratio: 256 logic elements with 78 I/Os in a 100-pin LQFP package offers high I/O availability for small form-factor designs.
• Flexible supply support: Operates across 1.71 V to 3.465 V, allowing integration into systems with varied power domains.
• Reduced BOM and simplified board design: Non-volatile configuration and on-chip control features reduce external components and assembly complexity.
• Commercial-grade reliability: Specified for 0 °C to 85 °C operation and RoHS-compliant packaging for mainstream applications.
