LFE2-35SE-6FN484I

The LFE2-35SE-6FN484I is a field programmable gate array (FPGA) device from Lattice Semiconductor’s ECP2 family. It provides a balance of logic capacity, embedded memory, and high I/O count in a compact 484-ball BGA package suitable for industrial-grade applications.

With 32,000 logic elements, approximately 0.34 Mbits of embedded RAM, and 331 general-purpose I/Os, this device targets designs that require moderate logic density, substantial on-chip memory, and extensive external interfacing while operating across an industrial temperature range.

Key Features

• Core Logic  4,000 CLBs (configurable logic blocks) delivering 32,000 logic elements for implementing custom digital logic and control functions.
• Embedded Memory  Approximately 0.34 Mbits of on-chip RAM (339,968 bits) to support buffering, state storage, and local data processing.
• I/O Capacity  331 user I/Os to simplify external device interfacing and system integration with sensors, peripherals, and communication lines.
• Power  Single supply operating range from 1.14 V to 1.26 V to match system power-rail constraints and ensure predictable supply requirements.
• Package & Mounting  484-ball BGA (484-FPBGA, 23×23) in a surface-mount package for compact board-level integration and reliable solder attachment.
• Temperature & Grade  Industrial-grade device rated for operation from -40°C to 100°C for deployment in extended-temperature environments.
• Environmental Compliance  RoHS compliant, supporting regulatory and environmental requirements for many electronic products.

Typical Applications

• Industrial Control  Leverages industrial temperature range and robust logic density for control, sequencing, and real-time decision logic in factory and process automation systems.
• Multi‑I/O Interface  High I/O count (331) supports bridging, protocol translation, and dense peripheral connectivity in embedded systems and communication equipment.
• On‑chip Data Processing  Approximately 0.34 Mbits of embedded RAM combined with 32,000 logic elements enables local buffering and custom datapath implementations for mid‑range signal processing tasks.

Unique Advantages

• Balanced Logic and Memory:  32,000 logic elements paired with ~0.34 Mbits of RAM provides a practical mix of resources for versatile mid-range FPGA designs.
• Extensive I/O Availability:  331 general-purpose I/Os reduce the need for external multiplexers or I/O expanders, simplifying board-level design.
• Industrial Temperature Rating:  Specified operation from -40°C to 100°C supports deployment in thermally demanding environments.
• Compact BGA Footprint:  484-ball FPBGA (23×23) package allows high-pin-count connectivity in a relatively small PCB area for space-constrained applications.
• Low-Voltage Operation:  Narrow supply range (1.14 V to 1.26 V) supports consistent power-system integration and predictable device behavior.
• Regulatory Compliance:  RoHS compliance assists in meeting environmental requirements for commercial and industrial products.
