LCMXO256C-5TN100C

The LCMXO256C-5TN100C is a MachXO family Field Programmable Gate Array (FPGA) provided in a 100-pin LQFP package. It combines non-volatile configuration, instant-on behavior and reconfigurable logic to address common embedded glue logic, bus interfacing, power‑up control and control-logic tasks.

With 256 logic elements, up to 78 I/O pins and programmable I/O support, this commercial-grade device is suited for compact, low-latency control and interface functions where single-chip configuration and quick startup are valued.

Key Features

• Non-volatile single-chip architecture Instant-on operation with no external configuration memory required; supports in-field reconfiguration and background programming via JTAG.
• Reconfiguration and in-field updates TransFR™ Reconfiguration enables logic updates while the system operates; SRAM-based logic can be reconfigured in milliseconds.
• Low-power modes Sleep mode capability that provides up to 100× reduction in static current for lower standby power.
• Logic capacity 256 logic elements (LUT-based) suitable for glue logic, control paths and interface translation.
• On-chip memory Approximately 2.0 Kbits of distributed RAM; no embedded block RAM (EBR) for this device variant.
• Flexible I/O Up to 78 general-purpose I/O pins with programmable I/O buffer support for a wide range of interface standards (LVCMOS, LVTTL, PCI, LVDS, Bus-LVDS, LVPECL, RSDS as supported by the MachXO family).
• Power and supply Operates across a nominal supply range specified for this part (1.71 V to 3.465 V) to accommodate common system voltages.
• Package and temperature 100-pin LQFP (14 × 14 mm) package; commercial operating temperature range 0 °C to 85 °C; RoHS compliant.
• System-level support Built-in features from the MachXO family include JTAG programming, boundary-scan (IEEE 1149.1) and on-chip oscillator support for simplified system integration.

Typical Applications

• Glue Logic and Bus Bridging — Implement address decoding, bus steering and protocol bridging between subsystems.
• Power-up and Reset Control — Manage sequencing, supervision and deterministic startup for multi‑rail systems.
• Interface Translation — Handle level shifting and protocol conversion using the programmable I/O and flexible logic.
• User Interface and Control — Support keypad, LED, and simple human‑machine interface logic with compact footprint.

Unique Advantages

• Instant-on, non-volatile operation: Eliminates external configuration memory and delivers microsecond startup for time-sensitive systems.
• Single-chip solution: Integrates configuration and reconfigurable logic to reduce BOM and simplify board-level design.
• High I/O-to-logic density: 78 I/Os paired with 256 logic elements makes it efficient for I/O-heavy glue and interfacing tasks.
• In-field reconfigurability: TransFR™ capability enables updates and feature changes without full system downtime.
• Low-power standby: Sleep mode significantly reduces static current for power-sensitive applications.
• Commercial-grade, RoHS compliant packaging: Ready for mainstream embedded and electronics applications with standard temperature range and lead‑free packaging.
