LCMXO256C-4TN100I

The LCMXO256C-4TN100I is a MachXO-series non-volatile FPGA optimized for glue logic, bus interfacing and system control applications. It integrates 256 logic elements arranged across 32 logic blocks with 78 user I/O pins in a 100-pin surface-mount package, delivering an instant-on, single-chip programmable solution for industrial designs.

As part of the MachXO family, this device emphasizes instant-on operation, flexible in-field reconfiguration and a wide range of programmable I/O options to simplify board-level design and reduce system BOM.

Key Features

• Non-volatile, instant-on  Powers up in microseconds with single-chip configuration—no external configuration memory required.
• Reconfigurable architecture  Supports in-field reconfiguration and background programming through JTAG; TransFR™ (in-field logic update) capability allows updates while the system operates.
• Low-power modes  Sleep mode capability can reduce static current by up to 100× for power-sensitive applications.
• Logic density and I/O  256 logic elements across 32 logic blocks with 78 I/O pins provides a balance of logic and connectivity for glue-logic and control tasks.
• Flexible sysIO™ buffer options  Family-level programmable I/O supports 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.
• Voltage and temperature  Supported supply range from 1.71 V to 3.465 V and industrial operating temperature from −40 °C to 100 °C for harsh-environment deployment.
• Package and mounting  Surface-mount 100-pin LQFP package (supplier package listed as 100-TQFP, 14 × 14 mm) for standard SMT assembly processes.
• Regulatory  RoHS-compliant packaging.

Typical Applications

• System glue logic  Replace multiple discrete gates and small CPLDs with a single programmable device for board-level signal steering and control.
• Bus bridging and interfacing  Implement protocol adaptation and pin multiplexing using the device's abundant I/O and programmable buffer options.
• Power-up and reset control  Leverage instant-on behavior and single-chip configuration to manage sequenced power rails and system bring-up.
• Embedded control and state machines  Implement control logic, monitoring and simple state machines within a compact, industrial-grade FPGA.

Unique Advantages

• Single-chip, secure configuration: Non-volatile architecture eliminates external configuration memory and bitstream exposure at power-up.
• Instant system responsiveness: Microsecond power-up lets designs resume operation quickly after power cycles or resets.
• Field-updatable logic: TransFR™ and JTAG-programmable non-volatile memory enable firmware-like updates without removing the device.
• High I/O-to-logic ratio: 78 I/Os paired with 256 logic elements supports dense interfacing tasks while keeping board area minimal.
• Industrial robustness: Rated for −40 °C to 100 °C and supplied in RoHS-compliant surface-mount packaging suitable for industrial applications.
