LFE5UM-45F-7MG285I

The LFE5UM-45F-7MG285I is an ECP5 family FPGA from Lattice Semiconductor. It delivers a balance of programmable logic, embedded memory, and I/O capacity in a compact 285-ball LFBGA/CSPBGA package targeted for industrial applications.

This device provides up to 44,000 logic elements, approximately 1.99 Mbits of on-chip RAM, and 118 user I/O, making it suitable for designs that require moderate-density logic plus memory and flexible interfacing within an industrial temperature range.

Key Features

• Programmable Logic — 44,000 logic elements and 11,000 CLBs provide the fabric resources required for medium-density FPGA designs.
• Embedded Memory — Approximately 1.99 Mbits of total on-chip RAM for buffering, state storage, and memory-mapped logic functions.
• I/O Capacity — 118 user I/O pins to support multiple interfaces and peripheral connections.
• Package & Mounting — 285-LFBGA (285-CSFBGA, 10×10) package in a surface-mount form factor for compact board layouts.
• Industrial Temperature Grade — Rated operating temperature from −40 °C to 100 °C for deployment in industrial environments.
• Power Supply — Core supply operating range of 1.045 V to 1.155 V to align with system power domains.
• Standards & Compliance — RoHS compliant for environmental and regulatory compatibility.
• Family-Level Capabilities — ECP5-series architecture (as documented in the ECP5 family datasheet) includes clocking networks, DDR memory support, SERDES, programmable I/O cells, and DSP-oriented slices described in the product family documentation.

Typical Applications

• Industrial Control — Use the device’s 118 I/O and industrial temperature rating for sensor interfacing, control logic, and industrial automation systems.
• Communications & Networking — ECP5 family features such as SERDES and flexible I/O make the device suitable for mid-rate networking and interface bridging tasks.
• Memory Subsystems & DSP Acceleration — Approximately 1.99 Mbits of embedded RAM and the family’s sysDSP capabilities support buffering, datapath acceleration, and DDR memory interfacing.

Unique Advantages

• Highly integrated logic and memory: 44,000 logic elements combined with ~1.99 Mbits of embedded RAM reduces external component needs for many designs.
• Industrial operating range: −40 °C to 100 °C rating supports deployment in temperature-challenging environments.
• Compact BGA footprint: 285-ball LFBGA (285-CSFBGA, 10×10) enables high-density board layouts while maintaining surface-mount assembly.
• Flexible I/O resources: 118 I/O pins provide broad interfacing options for peripherals, sensors, and external memory.
• Controlled core supply window: A specified voltage range of 1.045 V to 1.155 V helps integration into regulated system power domains.
• RoHS compliant: Meets common environmental compliance requirements for modern electronic assemblies.
