LFE2-35E-5FN672C

The LFE2-35E-5FN672C is an ECP2 family Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation designed for commercial-grade programmable logic applications. It provides a balance of logic capacity, embedded memory, and a high I/O count in a compact 672-ball BGA package.

With 32,000 logic elements, approximately 0.34 Mbits of embedded memory and up to 450 I/O, this device targets designs that require dense FPGA logic and extensive external interfacing while operating within a 1.14 V to 1.26 V supply range and a 0 °C to 85 °C commercial temperature window.

Key Features

• Core Logic  Provides 32,000 logic elements to implement complex programmable logic and custom digital functions.
• Embedded Memory  Includes approximately 0.34 Mbits (339,968 bits) of on-chip RAM for buffering, packet storage, and small data structures.
• High I/O Count  Up to 450 I/O pins to support extensive external device interfacing and high-pin-count system designs.
• Supply Voltage  Operates from 1.14 V to 1.26 V, enabling integration with low-voltage system domains.
• Package and Mounting  Available in a 672-ball BGA (supplier device package 672-FPBGA, 27×27) with surface-mount mounting for dense PCB implementations.
• Operating Range  Commercial grade operation specified from 0 °C to 85 °C for standard commercial deployments.
• Environmental Compliance  RoHS compliant to meet common lead-free manufacturing requirements.

Typical Applications

• High-density digital logic  Use the 32,000 logic elements to implement custom state machines, protocol processors, and glue logic that require substantial programmable resources.
• Buffering and small data storage  Leverage approximately 0.34 Mbits of on-chip RAM for packet buffering, FIFOs, and temporary data storage.
• Multi-interface systems  Deploy the device in systems needing many external connections—up to 450 I/O—to interface with peripherals, sensors, or external memories.
• Compact, PCB-dense designs  The 672-BBGA (27×27) package and surface-mount mounting suit space-constrained boards where high integration is required.

Unique Advantages

• High logic density: 32,000 logic elements allow substantial on-chip implementation of custom logic without immediately resorting to external ASICs or additional FPGAs.
• Meaningful on-chip memory: Approximately 0.34 Mbits of embedded RAM reduces dependence on external memory for short-term storage and buffering.
• Extensive I/O availability: Up to 450 I/O pins simplify system partitioning and minimize the need for additional I/O expanders.
• Compact BGA packaging: The 672-BBGA (672-FPBGA, 27×27) package supports high-density board layouts while maintaining a conventional BGA assembly flow.
• Commercial operating range: Specified 0 °C to 85 °C operation aligns with general-purpose electronic products and standard commercial deployments.
• RoHS compliant: Meets common environmental requirements for lead-free manufacturing processes.

Why Choose LFE2-35E-5FN672C?

The LFE2-35E-5FN672C combines substantial logic capacity, meaningful embedded memory, and a very high I/O count in a single commercial-grade FPGA package from Lattice Semiconductor Corporation.
