LCMXO640E-3TN100I

The LCMXO640E-3TN100I is a MachXO family, non-volatile FPGA optimized for glue logic, bus bridging, power-up control and control-logic tasks. This surface-mount, industrial-grade device integrates 640 logic elements with 74 user I/Os in a 100-pin LQFP package, delivering instant-on, single-chip configurability without the need for external configuration memory.

Designed for embedded and system control segments that require deterministic startup and on-board reconfiguration, the device combines MachXO family capabilities—such as instant-on, background non-volatile programming and in-field reconfiguration—with industrial temperature and core-voltage specifications for reliable operation in demanding environments.

Key Features

• Core Logic  Approximately 640 logic elements for implementing glue logic, control paths and interfacing functions.
• Memory  Approximately 6.1 Kbits of distributed RAM for small FIFOs and temporary storage; no embedded block SRAM blocks are provided for this device.
• I/O  74 user I/Os available in the 100-pin package, enabling broad interfacing to buses, sensors and peripheral devices.
• Non-Volatile Configuration  MachXO family instant-on single-chip architecture; no external configuration memory required and support for in-field reconfiguration.
• Low-Power Modes  Family support for Sleep Mode, enabling significant static current reduction during low-activity periods.
• Power Supply (core)  Specified core voltage range of 1.14 V to 1.26 V for the device.
• Package & Mounting  Surface-mount 100-LQFP package. Supplier device package listed as 100-TQFP (14×14 mm).
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C for industrial applications.
• Standards & Programming  MachXO family supports JTAG-based programming and background non-volatile memory programming (family-level capability).

Typical Applications

• Glue Logic and Board-Level Control  Implement address decoding, protocol conversion and control sequencing where compact, reconfigurable logic is required.
• Bus Bridging and Interfacing  Bridge between legacy and modern buses or adapt signal levels using the device’s flexible I/O count and reprogrammability.
• Power-Up and Reset Control  Provide deterministic instant-on behavior and manage system power-up sequencing without external configuration memory.
• Embedded Control Logic  Replace small CPLD functions with a single-chip, non-volatile FPGA for user interfaces, doorkeeping logic, and peripheral control.

Unique Advantages

• Instant-on Single-Chip Configuration: Eliminates the need for external configuration memory, enabling immediate operation at power-up and simplifying BOM.
• In-field Reconfiguration: MachXO family support for background and in-system programming lets you update logic while the system remains in service.
• Industrial Robustness: Industrial-grade temperature rating (−40 °C to 100 °C) and surface-mount packaging suited for embedded and industrial electronics.
• Compact Integration: 640 logic elements and 74 I/Os in a 100-pin package provide a dense solution for board-level glue and control without large FPGA overhead.
• Low Static Power Options: Sleep mode support at the family level enables substantial static current reduction for power-sensitive applications.
