Overview of LFE5U-45F-7TG144C – ECP5 Field Programmable Gate Array (FPGA) IC 98 1990656 44000 144-LQFP

The LFE5U-45F-7TG144C is a commercial-grade field programmable gate array (FPGA) IC provided in a 144-LQFP package. It integrates approximately 44,000 logic elements, roughly 1.99 Mbits of embedded RAM, and 98 general-purpose I/Os to support mid-density programmable logic designs.

With a core supply range of 1.045 V to 1.155 V, surface-mount packaging and an operating temperature range of 0 °C to 85 °C, this device is targeted at system designs that require a balance of logic capacity, on-chip memory, and I/O connectivity in a compact TQFP/LQFP footprint.

Key Features

  • Logic Capacity — Approximately 44,000 logic elements to implement mid-density digital logic, custom glue-logic, and moderate FPGA fabric tasks.
  • Embedded Memory — Approximately 1.99 Mbits of on-chip RAM for buffers, FIFOs, and small data structures without external memory.
  • I/O Resources — 98 general-purpose I/Os to connect peripherals, buses and interfaces directly to the FPGA fabric.
  • Power — Core supply voltage range of 1.045 V to 1.155 V suited for the device’s internal logic requirements.
  • Package & Mounting — 144-LQFP package (supplier device package 144-TQFP, 20×20 mm); surface mount for standard PCB assembly processes.
  • Operating Conditions — Commercial operating temperature range of 0 °C to 85 °C.
  • Environmental Compliance — RoHS compliant.

Typical Applications

  • Embedded logic and glue-logic — Use the device’s ~44,000 logic elements and abundant I/Os for custom interfacing and protocol adaptation on compact PCBs.
  • Buffering and small data storage — Leverage approximately 1.99 Mbits of on-chip RAM for temporary data storage, FIFOs, and packet buffering without external memory.
  • Prototyping and development — The 144-LQFP surface-mount package and commercial temperature grade make the device suitable for engineering prototypes and lab systems.

Unique Advantages

  • Significant logic density: Approximately 44,000 logic elements provide ample capacity for mid-range programmable designs while maintaining a compact footprint.
  • Embedded memory availability: Approximately 1.99 Mbits of on-chip RAM reduces reliance on external memory components for many buffering and storage tasks.
  • Flexible I/O count: 98 I/Os support a wide variety of peripheral connections and board-level interfaces without immediate need for expansion.
  • Compact, surface-mount package: 144-LQFP (supplier 144-TQFP, 20×20 mm) simplifies PCB layout and assembly for space-constrained applications.
  • Commercial temperature and RoHS compliance: Designed for commercial environments and compliant with RoHS requirements to aid regulatory alignment.
  • Stable core supply window: Narrow core voltage range (1.045 V–1.155 V) enables predictable power delivery planning for the FPGA core.
