LCMXO256E-4TN100I

The LCMXO256E-4TN100I is a MachXO family FPGA offering non-volatile, instant-on operation in a compact 100-pin LQFP package. It combines a grid of logic blocks with flexible programmable I/O to address glue logic, bus interfacing, power-up control and general-purpose control logic in industrial applications.

Designed for single-chip configuration with rapid start-up and in-field reconfiguration capabilities, this device targets systems that require reliable, low-BOM programmable logic with industrial temperature capability.

Key Features

• Core Logic  256 logic elements organized across 32 logic blocks, enabling compact implementation of glue logic and control functions.
• Non-Volatile Configuration  MachXO family non-volatile configuration provides instant-on power-up and single-chip operation without external configuration memory.
• Fast Reconfiguration & In-field Updates  Supports reconfiguration of SRAM-based logic in milliseconds and in-field logic updates (TransFR™) while the system operates.
• I/O and Package  78 I/Os in a 100-LQFP (100-TQFP, 14×14 mm) surface-mount package for straightforward board-level integration.
• Power  Core voltage supply range 1.14 V to 1.26 V (nominal 1.2 V) for system power planning.
• Low-Power Modes  Family-level sleep mode support enables up to 100× reduction in static current for reduced standby consumption.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C to meet industrial application requirements.
• Compliance  RoHS compliant packaging and surface-mount 100-LQFP case.
• No On-Chip RAM  Total RAM Bits: 0—suitable for control and interfacing tasks that primarily rely on logic and I/O.

Typical Applications

• Glue Logic  Replace discrete glue components with a single configurable device to simplify board design and reduce BOM.
• Bus Bridging and Interfacing  Implement protocol adaptation and bus-level interfacing where compact, reconfigurable logic and plentiful I/O are required.
• Power-Up and Initialization Control  Use instant-on, non-volatile configuration to manage power sequencing and fast system initialization.
• General Control Logic  Implement finite state machines, control gates, and timing logic for industrial control and embedded systems.

Unique Advantages

• Instant-on, Single-Chip Solution: Reduces system complexity by eliminating external configuration memory and enabling microsecond power-up.
• Field Reconfigurable: In-field reconfiguration (TransFR™) and rapid SRAM reprogramming let you update logic without removing the device from the system.
• Industrial-Rated Operation: −40 °C to 100 °C rating and surface-mount 100-LQFP packaging support deployment in harsh environments.
• Compact I/O Count in Small Package: 78 programmable I/Os in a 14×14 mm package balance board space and connectivity needs.
• Power-Efficient Standby: Sleep mode capability enables significant static current reduction for low-power designs.
• RoHS Compliant: Lead-free packaging for regulatory and environmental compatibility.
