LCMXO256C-3TN100C

The LCMXO256C-3TN100C is a MachXO family FPGA offering 256 logic elements and 78 programmable I/Os in a compact 100-pin surface-mount package. It is designed for low- to mid-density glue logic, bus interfacing, power-up control and board-level control functions where a single-chip, reconfigurable solution is preferred.

As part of the MachXO family, this device provides non-volatile, instant-on operation with single-chip configuration and in-field reconfiguration capabilities. Its combination of I/O density, commercial-grade temperature range and broad supply voltage support makes it suitable for a wide range of commercial embedded designs.

Key Features

• Core Logic 256 logic elements for implementing glue logic, bus bridging and control functions in compact designs.
• Non-Volatile Configuration MachXO family non-volatile architecture provides instant-on behavior and a single-chip solution with no external configuration memory required. Supports background programming and in-field reconfiguration (TransFR™).
• Reconfiguration & Programming SRAM and non-volatile memory are programmable through JTAG; supports background programming and field updates to minimize system downtime.
• I/O and Interfaces 78 I/Os in the 100-pin package provide high I/O-to-logic density. Programmable I/O buffers support a wide range of interface standards typical to the MachXO family (including LVDS, Bus-LVDS, LVPECL, RSDS, PCI and LVCMOS/LVTTL families).
• Clocking This device implements the LCMXO256 family configuration, which does not include analog PLLs.
• Power and Low-Power Modes Operates across a supply range of 1.71 V to 3.465 V. MachXO family features include a Sleep Mode enabling substantial static current reduction for low-power standby.
• Package and Mounting Surface-mount 100-pin LQFP (100-TQFP, 14 × 14 mm supplier package) for compact board-level integration.
• Operating Range and Compliance Commercial grade operating temperature 0 °C to 85 °C. RoHS-compliant packaging.
• On-chip Memory Total on-chip RAM bits as specified: 0.

Typical Applications

• Glue Logic and Board-Level Control Implement address decoding, bus arbitration and control-state machines where compact, reconfigurable logic is required.
• Bus Bridging and Interfacing Bridge between different buses and translate signaling standards using the device’s flexible I/O and high I/O count.
• Power-Up and Reset Control Provide deterministic power sequencing and reliable system initialization with instant-on, single-chip configuration.
• Peripheral and Sensor Interface Consolidate multiple I/O translations and simple preprocessing for sensors and peripherals in space-constrained commercial applications.

Unique Advantages

• Instant-on, Single-Chip Configuration: Eliminates external configuration memory and enables immediate operation at power-up, simplifying system design.
• High I/O Density in a Small Package: 78 I/Os in a 100-pin LQFP package provide flexible connectivity without large-package thermal or PCB constraints.
• Field Reconfigurability: TransFR™ and JTAG-programmable non-volatile/SRAM configuration allow in-system updates and background programming to reduce downtime.
• Low-Power Standby: Sleep Mode capability provides substantial static current reduction for power-sensitive applications.
• Commercial-Grade Reliability: Specified for 0 °C to 85 °C operation with RoHS-compliant packaging for standard commercial deployments.
• Flexible Supply Range: Supports a wide supply voltage window (1.71 V to 3.465 V) to match a variety of system power rails.
