LCMXO640C-3TN100I

The LCMXO640C-3TN100I is a MachXO family field-programmable gate array designed for medium-density logic integration. It combines non-volatile configuration with FPGA-style lookup-table logic to address glue logic, bus bridging and interfacing, power-up control, and general control logic in industrial applications.

With 640 logic elements, 74 I/Os and single-chip instant-on behavior, the device targets designs that require compact, reconfigurable control and interfacing while operating across a wide supply and temperature range.

Key Features

• Core Logic 640 logic elements provide medium-density implementation capacity for glue logic, control paths and protocol bridging.
• Memory MachXO family devices include distributed RAM capabilities; the LCMXO640 family member supports family-level distributed RAM for localized data storage.
• Programmable I/O 74 I/O pins in the 100-pin package support flexible interfacing for a wide range of external peripherals and buses.
• Non-volatile, Instant-On Configuration Single-chip, non-volatile configuration provides microsecond power-up behavior and removes the need for external configuration memory.
• In-field Reconfiguration Supports in-field updates and background programming of non-volatile memory, enabling system updates without removing the device from the board.
• Low-power Modes Sleep mode capability can reduce static current by up to 100× for low-power standby operation.
• Supply and Temperature Wide operating voltage range from 1.71 V to 3.465 V and industrial temperature rating of −40 °C to 100 °C for reliable operation in demanding environments.
• Package Options Available in a 100-pin LQFP package; supplier device package shown as 100-TQFP (14×14 mm), enabling standard surface-mount assembly.
• Standards and Compliance RoHS compliant for environmental and manufacturing compatibility.
• Design Tool Support MachXO family devices are supported by ispLEVER design tools for synthesis, place-and-route and timing verification.

Typical Applications

• Glue Logic and System Control Replace discrete logic and simplify board design by consolidating control functions into a single programmable device.
• Bus Bridging and Interfacing Implement protocol translation and bus interfacing for mixed-voltage systems using the device’s flexible I/O and programmable logic.
• Power-Up and Reset Management Provide deterministic power-up sequencing and control logic with instant-on configuration and non-volatile storage.
• Embedded Control and Peripheral Aggregation Aggregate multiple peripheral interfaces and offload simple state machines or control routines from a host processor.

Unique Advantages

• Single-chip, non-volatile FPGA: Eliminates external configuration memory and enables fast, deterministic power-up.
• Medium-density integration: 640 logic elements and 74 I/Os reduce board-level BOM by consolidating multiple discrete components.
