LFEC3E-3T100I

The LFEC3E-3T100I is an EC Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation supplied in a 100-pin LQFP package. The device integrates 3,100 logic elements and approximately 56 kbits of on-chip RAM, providing a compact, industrial-grade programmable logic option for embedded designs.

With 67 available I/O pins, surface-mount packaging, a low-voltage supply range of 1.14 V to 1.26 V and an operating temperature range of -40 °C to 100 °C, this FPGA targets industrial applications that require moderate logic density, flexible I/O and reliable operation across extended temperature ranges.

Key Features

• Core Logic 3,100 logic elements for implementing custom digital logic and control functions within a compact FPGA footprint.
• Embedded Memory Approximately 56 kbits (56,320 bits) of on-chip RAM to support buffering, state machines and small data storage needs.
• I/O Capacity 67 general-purpose I/Os to interface with peripherals, sensors and external logic in mixed-signal systems.
• Power Low-voltage supply operation from 1.14 V to 1.26 V suitable for designs with tight power budgets and modern low-voltage domains.
• Package & Mounting Available in a 100-LQFP package (supplier device package: 100-TQFP, 14 × 14 mm) and designed for surface-mount assembly.
• Temperature & Grade Industrial-grade device rated for operation from -40 °C to 100 °C for use in environments with extended temperature requirements.
• Regulatory RoHS compliant to meet common environmental and manufacturing requirements.

Typical Applications

• Industrial Control – Use where industrial temperature ratings and a mix of logic and I/O are needed for control, monitoring or interface tasks.
• Embedded Logic and Glue – Implement protocol bridging, glue logic and custom control functions within compact PCB layouts thanks to the 100-LQFP package and surface-mount mounting.
• Prototyping and Evaluation – Small to mid-scale FPGA designs that require 3,100 logic elements and on-chip RAM for developing and validating embedded logic.

Unique Advantages

• Balanced Logic and Memory: 3,100 logic elements paired with approximately 56 kbits of RAM provide a practical combination for mid-density designs without excessive board area.
• Ample I/O Count: 67 I/Os enable direct interfacing to multiple peripherals and sensors, reducing the need for external I/O expanders.
• Industrial Temperature Rating: Rated from -40 °C to 100 °C to support deployed equipment that must tolerate wide temperature swings.
• Low-Voltage Operation: Narrow supply range of 1.14 V to 1.26 V allows integration into low-voltage system domains.
• Compact Surface-Mount Package: 100-LQFP (100-TQFP, 14 × 14 mm) package supports dense PCB layouts and standard assembly processes.
• RoHS Compliant: Meets common environmental compliance requirements for modern electronics manufacturing.
