LFEC1E-4QN208I

The LFEC1E-4QN208I is an EC-family Field Programmable Gate Array (FPGA) optimized for mainstream, cost-sensitive designs that require moderate logic density and flexible I/O. It integrates approximately 1.5K logic elements with embedded memory and system clock resources in a 208-pin BFQFP package for compact board-level implementations.

Targeted at embedded and industrial applications, this device provides a balance of programmable logic, on-chip memory, and configurable I/O while supporting industrial operating conditions and RoHS compliance.

Key Features

• Core Logic  1500 logic elements providing the programmable fabric for custom digital functions and moderate complexity designs.
• On-Chip Memory  Approximately 18 Kbits (18,432 bits) of total RAM for embedded and distributed memory needs.
• I/O Capacity  112 I/O pins in the 208-BFQFP package for a broad range of peripheral connections and interface options.
• Package and Mounting  208-BFQFP (supplier device package: 208-PQFP, 28 × 28 mm) surface-mount package suitable for space-conscious PCB layouts.
• Voltage Supply  Core supply specified from 1.14 V to 1.26 V to match system power rails and design constraints.
• Operating Temperature  Industrial temperature range from −40 °C to 100 °C for deployment in demanding environments.
• Clocking and System Support  Family-level support includes multiple PLLs for clock multiplication, division and phase control (series documentation references up to two PLLs for this device class).
• Memory Interface and System-Level Features  Series documentation indicates dedicated DDR memory interface support and system-level features such as boundary scan and SPI boot flash interface.
• Regulatory Compliance  RoHS compliant for environmental and regulatory compatibility.

Typical Applications

• Industrial Control and Automation  Use the LFEC1E-4QN208I for control logic, I/O aggregation, and protocol bridging where industrial temperature range and robust I/O count are required.
• Embedded Communications  Implement interface logic, packet handling, or glue logic between processors and peripherals using the device’s flexible I/O and on-chip memory.
• Sensor and Data Acquisition  Aggregate and pre-process sensor signals with the FPGA’s programmable fabric and abundant I/O resources.
• Memory Interface and Buffering  Leverage family-level DDR support for designs requiring dedicated memory interface logic and data buffering.

Unique Advantages

• Balanced Logic and Memory  1500 logic elements combined with approximately 18 Kbits of on-chip RAM enable a wide range of embedded functions without external memory for many use cases.
• Compact, High‑Pin Count Package  208-pin BFQFP provides 112 I/Os in a 28 × 28 mm footprint, helping to reduce board area while keeping routing manageable.
• Industrial Temperature Range  Rated from −40 °C to 100 °C, suitable for deployment in temperature-demanding environments.
• Flexible Power Envelope  Narrow core supply window (1.14 V to 1.26 V) supports integration into tightly controlled power architectures.
• Series Ecosystem  Supported by the LatticeECP/EC family documentation and development tools and IP referenced in the series datasheet, easing design and migration within the family.
• RoHS Compliant  Meets RoHS requirements for environmentally conscious designs.
