LFE2-35SE-5F484C

The LFE2-35SE-5F484C is an ECP2 family field programmable gate array from Lattice Semiconductor Corporation. It provides a mid-range programmable fabric with 32,000 logic elements, approximately 0.34 Mbits of embedded memory, and up to 331 I/Os in a 484-ball BGA package.

Designed for commercial-grade embedded and electronic applications, this FPGA balances integration and I/O density with a low core supply voltage (1.14 V–1.26 V) and standard commercial operating range (0 °C–85 °C). Its surface-mount 484-FPBGA (23×23) package supports compact board-level implementations.

Key Features

• Core Logic: 32,000 logic elements for implementing custom digital functions and glue logic in a compact footprint.
• Embedded Memory: Approximately 0.34 Mbits of on-chip RAM to support buffering, FIFOs, and small data tables without external RAM.
• I/O Density: Up to 331 I/Os to support complex interfacing with peripherals, sensors, and external devices.
• Power Supply: Narrow core voltage range (1.14 V to 1.26 V) for predictable power budgeting and supply design.
• Package and Mounting: 484-ball BGA (484-FPBGA, 23×23) in a surface-mount format for high-density PCB assembly.
• Commercial Grade & Thermal Range: Rated for commercial operation from 0 °C to 85 °C, suitable for standard consumer and enterprise environments.
• Environmental Compliance: RoHS compliant for global assembly and regulatory requirements.

Typical Applications

• Consumer Electronics: Implement user interface control, video or audio preprocessing, and other custom logic within compact, surface-mount designs.
• Communications Equipment: Provide glue logic, protocol adaptation, and I/O aggregation where high pin count and flexible logic are needed.
• Embedded Systems: Integrate peripheral control, data buffering, and custom state machines directly in the FPGA fabric to reduce BOM and board complexity.
• Test & Measurement: Implement data collection front-ends, timing control, and preprocessing functions using the on-chip RAM and abundant I/O.

Unique Advantages

• Balanced Integration: Combines 32,000 logic elements with substantial I/O count to consolidate multiple discrete components into a single programmable device.
• Compact Packaging: 484-ball BGA (23×23) enables dense PCB layouts while delivering high I/O availability for complex boards.
• Predictable Power Envelope: Narrow supply voltage range (1.14 V–1.26 V) simplifies power-supply design and margining for system integrators.
• Embedded Memory On-Board: Approximately 0.34 Mbits of RAM reduces dependence on external memory for small buffers and control structures.
• RoHS Compliance: Environmentally compliant for a wide range of commercial manufacturing flows.
