LCMXO640C-4T144I

The LCMXO640C-4T144I is a non-volatile MachXO family FPGA optimized for glue logic, bus interfacing and system control functions. It combines a reconfigurable logic array with flexible programmable I/O in a single, instant-on device suitable for industrial applications.

With 640 logic elements and up to 113 I/Os in a 144-pin LQFP package, this device targets designs that require high pin-to-logic density, fast power-up behavior, and in-field reconfiguration while operating across a wide supply and temperature range.

Key Features

• Logic Capacity  640 logic elements and 80 CLBs (logic blocks) for implementing glue logic, control state machines and bus interfaces.
• I/O Density  113 programmable I/Os in a 144-LQFP (20×20 mm) package to support multiple peripheral connections and board-level signal routing.
• Non-volatile, Instant-on  Single-chip non-volatile configuration with instant-on behavior (powers up in microseconds) and no external configuration memory required.
• Reconfiguration  SRAM-based logic can be reconfigured in milliseconds and the family supports in-field logic updates (TransFR™ reconfiguration).
• Embedded and Distributed Memory  MachXO family devices provide distributed RAM; for the LCMXO640 family member this includes approximately 6.1 Kbits of distributed RAM and no embedded block SRAM.
• Flexible sysIO™ Buffering  Programmable I/O supports a wide range of interfaces and I/O standards (including multiple LVCMOS voltage options, LVTTL, PCI, LVDS, Bus‑LVDS, LVPECL and RSDS).
• Low-Power Modes  Sleep mode capability for substantial static current reduction (up to 100× reduction reported for the family).
• Industrial Grade  Specified operating temperature from −40 °C to 100 °C and wide supply range from 1.71 V to 3.465 V, suitable for industrial environments.
• RoHS Compliant  Manufactured to meet RoHS requirements.

Typical Applications

• Glue Logic and System Control  Implement resets, power sequencing and control state machines using compact, non‑volatile logic.
• Bus Bridging and Interfacing  Create custom protocol bridges and IO translators taking advantage of the programmable sysIO buffers and the device’s I/O count.
• Peripheral and Sensor Aggregation  Aggregate and manage multiple sensors or peripherals at the board level using the device’s I/O density and reconfigurable logic.
• Power-up and Reset Management  Use instant-on behavior and single-chip configuration to simplify power-up sequencing and minimize boot-time dependencies.

Unique Advantages

• Single‑chip, non‑volatile configuration: Reduces BOM and eliminates the need for external configuration memory while providing instant-on capability.
• High pin-to-logic density: 113 I/Os paired with 640 logic elements enable compact implementations of complex interface logic without large FPGA overhead.
• In-field reconfiguration: Support for fast reprogramming and background programming allows updates and fixes without removing the device from the system.
• Wide supply and temperature range: Operates from 1.71 V to 3.465 V and −40 °C to 100 °C to meet industrial environment requirements.
• Flexible I/O standards: Programmable sysIO buffers support multiple signaling standards to simplify board-level integration with diverse peripherals.
• Low-power standby: Sleep mode enables significant static current reduction for power-sensitive designs.
