LFEC1E-4TN144C

The LFEC1E-4TN144C is an EC family Field Programmable Gate Array (FPGA) from Lattice Semiconductor, offering a compact, low-cost FPGA fabric aimed at mainstream and cost-sensitive designs. Built on the LatticeECP/EC architecture, this device provides a balance of logic capacity, embedded memory, flexible I/O and system-level features suited for a wide range of commercial embedded applications.

This device is supplied in a 144-pin LQFP package and targets designs that require up to 1,500 logic elements, approximately 18 Kbits of on-chip RAM and up to 97 I/O pins while running from a low-voltage supply (1.14–1.26 V) within a commercial temperature range.

Key Features

• Core Logic  1,500 logic elements (LUT-based fabric) providing the programmable logic capacity for glue logic, control and small to medium FPGA functions. The family selection lists PFUs/PFFs at 192 for LFEC1-class devices.
• Memory  Approximately 18 Kbits of on-chip RAM (18,432 total bits) implemented as embedded block RAM (EBR) resources and distributed RAM for flexible data storage.
• I/O and Packaging  Up to 97 I/O pins in a 144‑LQFP package. Supplier package notation is 144‑TQFP (20 × 20 mm), enabling compact PCB layouts.
• Power  Low-voltage core operation with a specified supply range of 1.14 V to 1.26 V, suitable for power-conscious designs.
• Clocking  Device-level PLL resources (2 PLLs listed for LFEC1 devices) for clock multiplication, division and phase control to support system timing needs.
• System-level Support  Family-level features include IEEE 1149.1 boundary scan and SPI boot flash interface support as part of the LatticeECP/EC feature set referenced for this device family.
• Environmental & Grade  Commercial-grade operating range of 0 °C to 85 °C and RoHS compliance for regulatory alignment.

Typical Applications

• Embedded control and glue logic: Use the LFEC1E-4TN144C to implement control state machines, protocol bridging and board-level logic consolidation in compact commercial systems.
• Interface and I/O expansion: With up to 97 I/Os and flexible I/O buffer support in the family, deploy this device for peripheral interfacing, bus bridging and signal routing tasks.
• Memory interface support: The device family includes dedicated DDR interface support; LFEC1-class devices are suitable for designs that require dedicated DDR memory interfacing at supported speeds.
• Cost-sensitive signal processing: With embedded block RAM and a sysDSP block on LFEC1-class devices, this FPGA can handle compact multiply/accumulate and preprocessing tasks in space- and cost-constrained designs.

Unique Advantages

• Compact package with ample I/O: 144-pin LQFP packaging delivers up to 97 I/Os in a small footprint, simplifying PCB layout for space-constrained products.
• Right-sized logic capacity: 1,500 logic elements provide an efficient solution for control, interfacing and mid-density logic tasks without over-provisioning.
• On-chip memory for deterministic buffering: Approximately 18 Kbits of embedded RAM enables localized data buffering and state storage, reducing external memory needs.
• Low-voltage core operation: Narrow supply range (1.14–1.26 V) supports designs optimized for low-power core rails.
• System features from the LatticeECP/EC family: Boundary scan, SPI boot interface and PLL resources give integration and bring-up benefits consistent with the family’s tool and IP ecosystem.
• RoHS compliant and commercial-grade: Meets RoHS requirements and operates across a commercial temperature range (0 °C to 85 °C) for general-purpose deployments.
