LFE5U-12F-6TG144I

The LFE5U-12F-6TG144I is an ECP5 field programmable gate array (FPGA) IC from Lattice Semiconductor Corporation, offering reconfigurable logic in a compact 144-pin LQFP/TQFP package. With 12,000 logic elements and approximately 0.59 Mbits of on-chip RAM, it provides a balance of logic density and embedded memory for industrial-grade embedded designs.

Designed for surface-mount deployment and industrial operating conditions, this device targets applications requiring flexible I/O, low-voltage operation, and extended temperature range.

Key Features

• Core Logic — 12,000 logic elements suitable for medium-density programmable logic implementations and custom logic acceleration.
• Embedded Memory — Approximately 0.59 Mbits of on-chip RAM to support buffers, small FIFOs, and state storage within the FPGA fabric.
• I/O Capability — 98 I/Os to support a wide set of external interfaces, peripheral connections, and board-level signal routing.
• Power — Supply voltage range from 1.045 V to 1.155 V to match low-voltage system rails and ensure predictable power behavior.
• Package and Mounting — Available in a 144-LQFP package case; supplier device package listed as 144-TQFP (20×20). Surface-mount mounting for PCB assembly.
• Industrial Grade and Temperature — Rated for industrial use with an operating temperature range of −40 °C to 100 °C for deployment in temperature-challenging environments.
• Regulatory — RoHS compliant for environmental and manufacturing requirements.

Typical Applications

• Industrial Control — Implement custom control logic, motor control interfaces, and deterministic I/O handling using the device’s industrial temperature rating and broad I/O count.
• Embedded Systems — Integrate protocol bridging and custom accelerators where the on-chip RAM and logic elements can offload tasks from a host processor.
• Communications and Networking — Use the available I/Os and programmable logic to perform packet processing, interface adaptation, or protocol conversion in mid-range networking modules.
• Sensor and Data Acquisition — Aggregate and pre-process sensor data with on-chip logic and memory before passing processed streams to downstream systems.

Unique Advantages

• Balanced Logic and Memory: 12,000 logic elements paired with approximately 0.59 Mbits of embedded RAM provide flexibility for both control logic and modest buffering needs.
• Generous I/O Count: Ninety-eight I/Os accommodate multiple interfaces and peripherals without extensive external glue logic.
• Industrial Temperature Range: Operational from −40 °C to 100 °C, enabling deployment in harsher environments where temperature resilience is required.
• Compact, Surface-Mount Package: 144-pin LQFP/TQFP footprint supports space-constrained board layouts while remaining compatible with standard surface-mount assembly processes.
• Low-Voltage Operation: Narrow supply range (1.045 V–1.155 V) supports integration into low-voltage systems with predictable power behavior.
• RoHS Compliant: Meets environmental compliance requirements for modern electronics manufacturing.
