The LFEC3E-4QN208I is an EC family Field Programmable Gate Array from Lattice Semiconductor Corporation designed for industrial embedded applications. It delivers a compact, surface-mount FPGA solution with 3,100 logic elements and 56,320 bits of on-chip RAM for custom logic, control and interface tasks.

Packaged in a 208-pin BFQFP (28 × 28 mm) and specified for industrial operation, the device targets mainstream designs that need flexible I/O, embedded memory and a low-voltage core supply.

Key Features

• Core Logic – 3,100 logic elements provide the programmable fabric for custom digital logic and control functions.
• Embedded Memory – 56,320 total RAM bits of on-chip memory to support register files, FIFOs and small buffer requirements.
• I/O Density – 145 I/O pins to connect a wide range of peripherals and external interfaces.
• Package & Mounting – 208-BFQFP (28 × 28 mm) in a surface-mount package suitable for compact PCB designs.
• Voltage Supply – Core supply range of 1.14 V to 1.26 V (nominal 1.2 V) to match low-voltage system domains.
• Industrial Temperature Rating – Specified for operation from -40 °C to 100 °C for use in industrial environments.
• Family-Level System Features – LatticeECP/EC family capabilities include dedicated DDR memory support, multiple analog PLLs, flexible programmable I/O buffers and system-level integration features such as SPI boot flash interface and IEEE 1149.1 boundary scan (as described for the LatticeECP/EC family).
• Compliance – RoHS compliant for environmental regulatory alignment.

Typical Applications

• Industrial Control – Custom logic, motor control interfaces and control-plane functions benefiting from industrial temperature qualification and flexible I/O.
• Embedded Systems – On-board glue logic, protocol conversion and system orchestration using available on-chip RAM and programmable logic.
• Memory-Interface Designs – Systems requiring dedicated DDR memory interface support at the family level can leverage the series’ DDR capabilities for external memory connectivity.
• High-Density I/O Bridging – Applications that need numerous and varied I/Os for sensors, ADC/DAC front ends or peripheral expansion.

Unique Advantages

• Industrial Temperature Range: Rated from -40 °C to 100 °C, enabling deployment in temperature-challenging industrial systems.
• Compact, High-IO Package: 208-pin BFQFP provides a high I/O count in a standard surface-mount footprint for space-constrained PCBs.
• Integrated Memory Resources: 56,320 bits of embedded RAM reduce the need for external SRAM for moderate buffering and control tasks.
• Low-Voltage Core: 1.14–1.26 V supply aligns with low-voltage system domains common in modern embedded designs.
• Family Ecosystem: Access to LatticeECP/EC family design tools and IP (as provided by the family datasheet) helps accelerate development and migration within the family.
• Regulatory Compliance: RoHS compliance supports environmental and manufacturing requirements.
