LFE5U-45F-8TG144C

The LFE5U-45F-8TG144C is an ECP5 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation in a 144-pin LQFP surface-mount package. It provides 44,000 logic elements and approximately 1.99 Mbits of embedded RAM (1,990,656 total RAM bits).

As a commercial-grade device, the part offers 98 I/O pins, a specified supply-voltage range of 1.045 V to 1.155 V, and an operating temperature range of 0 °C to 85 °C. These characteristics make it appropriate for designs that require a mid-range FPGA resource set in a 144-LQFP footprint.

Key Features

• Logic Capacity 44,000 logic elements for implementing combinational and sequential logic functions.
• Configurable Logic Blocks (CLBs) 11,000 CLBs noted for resource planning and partitioning of logic.
• Embedded Memory Approximately 1.99 Mbits of on-chip RAM (1,990,656 total RAM bits) for buffering, FIFOs, and state storage.
• I/O Count 98 user I/Os provided in the 144-LQFP package for interfacing with external peripherals and subsystems.
• Supply Voltage Operates within a supply range of 1.045 V to 1.155 V for the core domain.
• Package & Mounting 144-LQFP surface-mount package; supplier device package listed as 144-TQFP (20×20).
• Commercial Grade & Temperature Rated for commercial applications with an operating temperature range of 0 °C to 85 °C.
• RoHS Compliant Conforms to RoHS requirements for lead-free assembly.

Unique Advantages

• Balanced Logic and Memory 44,000 logic elements combined with approximately 1.99 Mbits of embedded RAM support mid-range designs that need both logic density and on-chip memory.
• Compact LQFP Footprint 144-LQFP surface-mount packaging provides a board-level option where a fine-pitch QFP is preferred for assembly and inspection.
• Generous I/O Count 98 I/O pins enable multiple peripheral and sensor connections while keeping the design in a single 144-pin package.
• Tight Core Voltage Window The specified 1.045 V to 1.155 V supply range allows predictable power budgeting for the core domain.
• Commercial Temperature Rating Rated 0 °C to 85 °C to match typical commercial-environment deployment requirements.
• Regulatory Compliance RoHS compliance supports lead-free manufacturing flows.
