LCMXO640E-4T144C

The LCMXO640E-4T144C is a MachXO family FPGA from Lattice Semiconductor that combines non-volatile configuration with FPGA-style logic flexibility. The device provides 640 logic elements and up to 113 I/Os in a 144-pin TQFP/LQFP package, targeting glue logic, bus bridging, interface control and other embedded control functions.

Built for single‑chip configuration and rapid startup, the MachXO architecture delivers instant-on operation, in-field reconfiguration options and a flexible I/O bank environment suitable for mixed-voltage designs. The device is supplied in a surface-mount 144-pin package and is graded for commercial temperature operation.

Key Features

• Logic Capacity — 640 logic elements (LUT-based) for implementing control, glue logic and protocol glue functions.
• Distributed Memory — MachXO family support for distributed RAM; LCMXO640 devices include approximately 6.1 Kbits of distributed RAM per the family specification.
• Non‑volatile, Instant‑on Configuration — Single-chip non-volatile configuration provides instant-on operation and eliminates the need for external configuration memory.
• Reconfiguration and Programming — Supports in-field reconfiguration and background programming; SRAM and non-volatile memory programmable through JTAG.
• Low‑power Modes — Sleep mode allows significant static current reduction for power-sensitive applications.
• Flexible I/O and Voltage Support — Up to 113 I/Os in the 144-pin package; MachXO family supports multiple I/O standards and device-level supply options (devices operate with 3.3V, 2.5V, 1.8V or 1.2V supply levels per family specification). Core supply for this part is specified at 1.14 V to 1.26 V.
• Package and Mounting — 144-pin LQFP/TQFP (20 × 20 mm) surface-mount package, suitable for compact board designs.
• Commercial Temperature Range — Rated for 0 °C to 85 °C operation and RoHS compliant.

Typical Applications

• Glue Logic and System Control — Replace multiple discrete components with a single programmable device for control-path consolidation and board-level simplification.
• Bus Bridging and Protocol Conversion — Implement bus interfacing, protocol conversion and signal conditioning between subsystems using the device’s flexible I/O and logic resources.
• Power‑Up and Reset Sequencing — Use non-volatile instant-on capability to manage system power-up sequencing and deterministic initialization.
• User Interface and Peripheral Control — Host control for displays, buttons, LEDs and peripheral timing where compact, reconfigurable logic is required.

Unique Advantages

• Single‑Chip, Secure Configuration: Non‑volatile on-chip configuration removes external config memory and reduces BOM while providing secure, instant-on startup.
• Fast Time-to‑Function: Instant-on and in-field reconfiguration capabilities enable rapid system readiness and on-the-fly updates without external storage devices.
• High I/O Density in a Small Package: 113 available I/Os in a 144-pin TQFP/LQFP package simplifies board layout while preserving connectivity for multiple peripherals.
• Flexible Power and I/O Options: Core supply range of 1.14–1.26 V combined with family-level support for multiple I/O voltages enables mixed-voltage system integration.
• Power Savings: Sleep mode support reduces static current for lower-power standby operation, aiding energy-sensitive designs.
• Proven Family Ecosystem: MachXO family features such as JTAG programming, background non‑volatile memory programming and industry-standard tools streamline development and deployment.
