LFE5UM-45F-6MG285I

The LFE5UM-45F-6MG285I is an ECP5‑family Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It delivers a mid-range programmable fabric with a mix of logic, embedded memory, and I/O suitable for industrial and embedded applications.

Built for designs that require flexible I/O, moderate on‑chip memory, and industrial temperature operation, this device integrates approximately 44,000 logic elements, about 1.99 Mbits of embedded memory, and 118 I/O pins in a 285‑ball LFBGA package.

Key Features

• Logic Capacity  Approximately 44,000 logic elements and around 11,000 logic blocks for implementing custom control, glue logic, and moderate-complexity datapaths.
• Embedded Memory  Approximately 1.99 Mbits of on‑chip RAM to support buffering, FIFOs, and small on‑chip datasets without external memory.
• I/O  118 user I/O pins to enable multiple peripheral interfaces, sensor connectivity, and board-level signaling.
• Package and Mounting  285‑LFBGA package (supplier device package 285‑CSFBGA, 10×10) with surface‑mount assembly for compact board designs.
• Power Supply  Core supply operating range from 1.045 V to 1.155 V to match system power rails and regulator designs.
• Industrial Temperature Grade  Specified for operation from −40 °C to 100 °C for reliable performance in demanding environments.
• Family Architecture  Part of the Lattice ECP5 family, providing a documented architecture and device-level features for programmable logic designs.
• RoHS Compliant  Meets RoHS requirements for lead‑free assembly and regulatory compliance in many markets.

Typical Applications

• Industrial Automation  Use in control and monitoring systems where industrial temperature rating and flexible I/O enable sensor interfacing and real‑time logic.
• Embedded Systems  Integration of custom peripherals, protocol bridging, and control logic within compact, surface‑mount PCB layouts.
• Communications and Networking  Protocol adaptation, packet processing glue logic, and I/O aggregation benefitting from the FPGA’s logic and memory resources.
• Test and Measurement  Custom front‑end processing, data buffering, and user‑configurable control for instrumentation and data acquisition systems.

Unique Advantages

• Balanced Logic and Memory  A combination of ~44,000 logic elements and ~1.99 Mbits of embedded RAM supports a wide range of mid‑complexity designs without immediate need for external memory.
• Generous I/O Count  118 I/O pins provide flexibility to connect multiple peripherals, sensors, and external devices directly to the FPGA fabric.
• Industrial Reliability  Operating range of −40 °C to 100 °C and RoHS compliance align the device with industrial application requirements.
• Compact Surface‑Mount Package  285‑LFBGA (285‑CSFBGA, 10×10) enables dense PCB layouts and compact system footprints.
• Predictable Power Envelope  Defined core voltage range (1.045 V–1.155 V) supports straightforward power‑supply planning and regulator selection.
