LFEC6E-3TN144C

The LFEC6E-3TN144C is a commercial-grade FPGA from Lattice Semiconductor’s EC family, offering a balanced combination of logic capacity, embedded memory, and flexible I/O in a compact 144-pin LQFP package. Built on the LatticeECP/EC architecture, it provides LUT-based logic, distributed and embedded memory, and phase-locked loop (PLL) resources suitable for mainstream programmable logic tasks.

This device targets commercial applications requiring mid-range logic density and moderate I/O count—delivering integration and design flexibility while operating within standard commercial voltage and temperature ranges.

Key Features

• Logic Capacity — 6,100 logic elements (logic cells) for implementing combinational and sequential logic, state machines, and glue logic.
• Embedded Memory — Total on-chip RAM of 94,208 bits for distributed and block memory needs within the design.
• I/O Resources — 97 user I/Os to support multiple peripherals, interfaces, and board-level connections.
• Voltage Supply — Operates from 1.14 V to 1.26 V, enabling compatibility with low-voltage system rails.
• Clocking — Includes PLL support as part of the LatticeECP/EC family architecture for clock management and phase control.
• Package & Mounting — 144-LQFP package (supplier designation: 144-TQFP, 20 × 20 mm) with surface-mount mounting for compact PCB layouts.
• Operating Range — Commercial temperature grade: 0 °C to 85 °C, suited for consumer and general-purpose commercial environments.
• Regulatory — RoHS compliant.
• Design Ecosystem — Part of the LatticeECP/EC family, which is supported by Lattice design tools and IP for streamlined implementation (family-level support).

Typical Applications

• Consumer and Commercial Electronics — Implement control logic, peripheral interfacing, and protocol bridging in compact products where commercial-grade operation and low-voltage operation are required.
• Embedded Control — Replace discrete glue logic and microcontroller offload for finite-state machines, interface adaptation, and custom timing logic.
• Prototyping and Evaluation — Use as a mid-density FPGA platform for proof-of-concept, algorithm testing, and early-stage system integration.
• Communication Interfaces — Support multi-pin serial/parallel interfaces and board-level signal aggregation with the device’s substantial I/O count.

Unique Advantages

• Mid-range logic in a compact package: 6,100 logic elements in a 144-LQFP package lets you implement significant logic without a large-footprint BGA device.
• Ample on-chip memory: 94,208 bits of embedded RAM reduce external memory requirements for many control and buffering tasks.
• Rich I/O availability: 97 I/Os provide flexibility for connecting sensors, displays, buses, and external peripherals directly to the FPGA.
• Low-voltage operation: 1.14–1.26 V supply range aligns with modern low-voltage system architectures to help minimize power rail complexity.
• Commercial temperature suitability: Rated 0 °C to 85 °C for deployments in consumer and general commercial environments.
• RoHS compliant: Meets common environmental requirements for lead-free designs.
