The LFEC1E-4TN100I from Lattice Semiconductor Corporation is a LatticeECP/EC family FPGA offered in a 100-pin LQFP/TQFP package. It provides a compact, industrial-grade programmable logic device with 1500 logic elements and 67 general-purpose I/Os for mainstream embedded and control applications.

Designed for board-level integration, this device combines a low-voltage core, on-chip memory and a small-footprint surface-mount package to address space-constrained designs that require reliable operation across a wide temperature range.

Key Features

• Logic Fabric  1500 logic elements provide configurable LUT-based logic resources suitable for glue logic, control state machines and modest FPGA tasks.
• On-chip Memory  Approximately 18 Kbits (18,432 bits) of total RAM bits for distributed or small block memory requirements within your design.
• I/O Count & Flexibility  67 I/O pins in the 100-pin package support a range of peripheral and interface connections for mixed-signal systems and digital peripherals.
• Power Supply  Core supply range of 1.14 V to 1.26 V to match low-voltage system power rails and enable power-optimized designs.
• Package & Mounting  Supplied in a 100-LQFP / 100-TQFP (14 × 14 mm) form factor with surface-mount mounting for compact PCB layouts.
• Operating Temperature & Grade  Industrial-grade device rated for operation from −40 °C to 100 °C, suitable for harsher environmental conditions.
• Compliance  RoHS-compliant construction for environmentally conscious manufacturing and regulatory alignment.
• Family Ecosystem  Part of the LatticeECP/EC family, which is supported by Lattice design tools and IP resources for mainstream FPGA development workflows.

Typical Applications

• Embedded Control  Compact logic implementations for device control, sequencing and system glue logic in industrial equipment.
• Interface Bridging  Protocol adaptation and I/O buffering where 67 available I/Os allow integration between peripherals and host controllers.
• User Interface & Peripheral Logic  Handling small-to-medium complexity UI logic, LED/display control and keypad or sensor aggregation.
• Proof-of-Concept and Low-Volume Designs  Low-pin-count FPGA solution for early development, evaluation boards and space-constrained prototypes.

Unique Advantages

• Compact, production-ready package: 100-pin LQFP/TQFP packaging minimizes PCB area while retaining a useful I/O count for many embedded designs.
• Industrial temperature range: −40 °C to 100 °C rating supports deployment in demanding environments without additional thermal qualification.
• Low-voltage core operation: 1.14 V–1.26 V supply compatibility helps designs that target modern low-voltage systems and reduced power budgets.
• On-chip memory reduces BOM: Approximately 18 Kbits of embedded RAM enables local buffering and small data structures without external SRAM.
• RoHS compliant: Aligned with environmental directives for manufacturing and supply-chain needs.
• Backed by a known FPGA family: Integration into the LatticeECP/EC family means access to established design tools and IP resources for faster development.
