LFE3-35EA-7FN484C

The LFE3-35EA-7FN484C is an ECP3 field programmable gate array (FPGA) IC designed for applications that require substantial programmable logic and flexible I/O in a compact BGA package. It integrates 33,000 logic elements and approximately 1.36 Mbits of embedded memory to support complex digital designs while operating from a low-voltage supply of 1.14 V to 1.26 V.

Packaged in a 484-ball BGA footprint with surface-mount assembly and offered as a commercial-grade device (0 °C to 85 °C), this FPGA provides a balance of density, I/O count and power efficiency for a range of programmable-logic implementations.

Key Features

• Core Logic — 33,000 logic elements provide substantial programmable logic capacity for implementing custom digital functions and state machines.
• Embedded Memory — Approximately 1.36 Mbits of on-chip RAM to support buffering, state storage and local data processing.
• I/O Density — 295 available I/O pins to accommodate high-pin-count interfaces and multiple parallel connections.
• Power Supply — Low-voltage operation with a supply range of 1.14 V to 1.26 V to align with modern low-voltage system environments.
• Package and Mounting — 484-ball BGA package (supplier package: 484-FPBGA, 23×23) in a surface-mount form factor for space-efficient board layouts.
• Operating Range — Commercial grade with an operating temperature range of 0 °C to 85 °C for standard commercial applications.
• Regulatory — RoHS compliant, supporting lead-free manufacturing processes.

Typical Applications

• High-density digital designs — Implement complex combinational and sequential logic using 33,000 logic elements and embedded RAM for local data handling.
• Multi-interface bridging — Leverage 295 I/Os to connect and translate between multiple parallel or serial interfaces on a single device.
• Prototyping and development — Use the FPGA’s logic capacity and memory to validate custom hardware functions and accelerate design iterations.

Unique Advantages

• Substantial logic capacity: 33,000 logic elements enable sizeable programmable designs without external logic expansion.
