LCMXO256E-3T100C

The LCMXO256E-3T100C is a MachXO family FPGA optimized for low-capacity, high-pin-count control and glue-logic functions. This non-volatile, instantly configurable device combines a small logic fabric with flexible I/O to address applications such as bus interfacing, power-up control, and general-purpose control logic.

With 256 logic elements, 78 I/Os, single‑chip non-volatile configuration and a compact 100-pin surface-mount package, the device targets compact embedded systems that require fast startup, in-field reconfiguration, and low part-count designs. It operates within a core supply range of 1.14 V to 1.26 V and a commercial temperature range of 0 °C to 85 °C.

Key Features

• Non-volatile, instant-on configuration  Single-chip non-volatile architecture enables microsecond power-up without external configuration memory.
• Reconfiguration capability  SRAM-based logic can be reconfigured in milliseconds and non-volatile memory is programmable via the JTAG interface for field updates.
• Sleep mode for low static current  Built-in sleep mode supports significant static current reduction for power-sensitive applications.
• TransFR™ in-field reconfiguration  Supports background logic updates while the system remains operational for in-field maintenance and upgrades.
• Logic density  Provides 256 logic elements suitable for glue logic, control tasks, and small-scale FPGA functions.
• Flexible I/O  78 I/O pins in a compact package, enabling multiple parallel interfaces and signal routing options on space-constrained boards.
• Package and mounting  Surface-mount 100-pin LQFP package for compact PCB integration.
• Supply and temperature  Core supply range: 1.14 V to 1.26 V; operating temperature: 0 °C to 85 °C (commercial grade).
• Compliance  RoHS compliant packaging.

Typical Applications

• Glue Logic and System Control  Implement board-level glue logic, reset sequencing and control functions with a compact, single‑chip solution.
• Bus Bridging and Interfacing  Serve as protocol adapters or bus interface controllers where multiple I/Os and fast startup are required.
• Power-Up and Reset Management  Manage power sequencing, watchdog logic and system bring-up with instant-on configuration.
• In-Field Logic Updates  Support field upgrades and incremental feature additions using TransFR™ reconfiguration without taking the system offline.

Unique Advantages

• Single-chip, secure configuration: Eliminates the need for external configuration memory, reducing BOM and attack surface for bitstream interception.
• Fast system availability: Instant-on behavior enables systems to begin operation in microseconds after power-up, improving responsiveness for control applications.
• Field maintainability: Background and in-field reconfiguration let you update logic while the system is running, simplifying firmware rollout and bug fixes.
• Power management flexibility: Sleep mode enables substantial static current reduction for lower standby power in battery-powered or energy-conscious systems.
• Compact integration: 78 I/Os and 256 logic elements in a 100-pin surface-mount package support high pin-to-logic density on small PCBs.
• Design tool support: Family documentation indicates toolchain support (ispLEVER) for synthesis, place-and-route, and timing verification to streamline development.
