LFE2-35E-5F484I

The LFE2-35E-5F484I is an ECP2-series Field Programmable Gate Array (FPGA) in a compact 484‑BBGA package intended for industrial applications. It provides mid-density programmable logic with a combination of logic elements, embedded memory, and a high I/O count suitable for systems that require flexible, on‑board logic integration.

Key attributes include 32,000 logic elements, approximately 0.34 Mbits of embedded RAM, up to 331 user I/O, low-voltage operation (1.14 V–1.26 V), and an industrial temperature range of -40 °C to 100 °C.

Key Features

• Logic Capacity: 32,000 logic elements to implement mid-density custom logic, protocol handling, and control functions.
• Embedded Memory: Approximately 0.34 Mbits of on‑chip RAM for data buffering, state storage, and small lookup tables.
• I/O Density: Up to 331 user I/O pins to support multiple parallel interfaces, sensor and actuator connections, or bus-level interfacing.
• Power Domain: Low-voltage core operation with a supply range of 1.14 V to 1.26 V for integration into low-power system architectures.
• Package & Mounting: 484‑BBGA package (supplier device package: 484‑FPBGA, 23×23) configured for surface-mount assembly in space-constrained boards.
• Industrial Temperature Rating: Specified operation from -40 °C to 100 °C for deployment in industrial environments.
• RoHS Compliance: Environmentally compliant, meeting RoHS requirements.

Typical Applications

• Industrial Control: Implement custom control logic, timing, and interfacing for factory automation and process control equipment using the device's logic capacity and wide operating temperature range.
• I/O Aggregation and Protocol Bridging: Consolidate multiple sensor and peripheral interfaces with the high I/O count and on‑chip RAM for buffering and protocol handling.
• Communications and Networking Modules: Use the programmable logic and I/O resources to implement data framing, interface adaptation, and mid‑rate packet handling functions.

Unique Advantages

• Balanced Mid‑Density Logic: 32,000 logic elements provide a practical trade-off between capability and system cost for mid-range programmable designs.
• Compact, High‑Pin Package: 484‑BBGA (484‑FPBGA, 23×23) offers a small PCB footprint while providing a large number of I/O for complex board-level integration.
• Industrial‑Grade Operation: Rated from -40 °C to 100 °C to meet environmental demands common in industrial deployments.
• Low-Voltage Core: 1.14 V–1.26 V core supply supports integration into modern low-power system architectures.
• On‑Chip Memory for System Tasks: Approximately 0.34 Mbits of embedded RAM supports buffering, FIFOs, and small data structures without an external memory component.
• RoHS Compliant: Supports regulatory requirements for environmentally conscious product designs.
