LCMXO256E-4T100I

The LCMXO256E-4T100I is a MachXO family FPGA optimized for glue logic, bus bridging, power-up control and control-logic applications. It combines non-volatile configuration with FPGA-style LUT-based logic to provide instant-on operation and flexible in-system reconfiguration.

Designed for industrial environments, this device delivers 256 logic elements, 78 user I/Os in a 100-pin LQFP package, and an operating temperature range of −40 °C to 100 °C, making it suitable for embedded control and interface roles where robustness and fast start-up are required.

Key Features

• Logic Capacity  256 logic elements organized across 32 logic blocks, enabling compact implementations of glue logic and control functions.
• I/O and Package  78 user I/Os in a 100-LQFP package (supplier package listed as 100-TQFP 14×14 mm), providing broad pin access in a small footprint.
• Non-volatile, Instant-on Architecture  Single-chip non-volatile configuration enables instant-on operation and removes the need for external configuration memory.
• Reconfiguration and In-field Updates  Supports background programming and TransFR™ reconfiguration for in-field logic updates while the system operates (family feature).
• Flexible I/O Standards  Programmable sysIO™ buffers support a wide range of interfaces including LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, PCI, LVDS, Bus-LVDS, LVPECL and RSDS (family feature).
• Power and Supply  Core voltage supply specified at 1.14 V to 1.26 V; family architecture supports multiple I/O voltage domains via programmable I/O.
• Low-Power Modes  Sleep mode capability to substantially reduce static current for power-sensitive applications (family feature).
• Industrial Temperature Grade  Rated for operation from −40 °C to 100 °C for deployment in industrial environments.
• Compliance  RoHS compliant packaging.

Typical Applications

• Glue Logic and System Control  Implement reset sequencing, startup control, and small-scale state machines with fast, non-volatile startup.
• Bus Bridging and Interface Glue  Bridge mismatched logic levels and protocols using the programmable I/O and wide standard support.
• Power-Up & Sequencing Control  Manage power-up sequencing and supervision with instant-on behavior and low-power sleep modes.
• Human-Machine Interface (HMI)  Drive and multiplex buttons, LEDs, and simple display interfaces while preserving board space in a 100-pin LQFP package.

Unique Advantages

• Instant-on, single-chip solution: Eliminates external configuration memory and enables microsecond-scale start-up for time-sensitive systems.
• Field reprogrammability: Background programming and TransFR reconfiguration allow updates to logic while the system remains operational.
• Flexible I/O support: Programmable sysIO buffers cover a broad set of interface standards, simplifying board-level voltage and protocol translation.
• Compact industrial footprint: 78 I/Os and 256 logic elements in a 100-LQFP package provide a dense feature set for space-constrained, industrial designs.
• Power-conscious operation: Sleep mode reduces static current for lower standby power in battery-backed or energy-sensitive applications.
• Regulatory and environmental readiness: RoHS-compliant packaging supports lead-free manufacturing flows.
