LFEC15E-3FN256C

The LFEC15E-3FN256C is a commercial-grade EC Field Programmable Gate Array (FPGA) from Lattice Semiconductor designed for mid-density embedded applications. Built on the LatticeECP/EC family architecture, it delivers a balanced combination of logic capacity, on-chip memory and a flexible I/O complement for a wide range of commercial embedded designs.

Key hardware attributes include approximately 15,400 logic elements, roughly 358 Kbits of embedded RAM, up to 195 user I/Os and a compact 256-ball fpBGA (17 × 17 mm) package. The device operates from a 1.14 V to 1.26 V core supply and is rated for 0 °C to 85 °C operation; it is RoHS compliant.

Key Features

• Logic Capacity  Approximately 15,400 logic elements suitable for mid-range designs that require substantial combinational and sequential logic resources.
• Configurable Logic Fabric  Part of the LatticeECP/EC family architecture, delivering mainstream FPGA fabric features such as LUT-based logic and placement/routing optimizations.
• Embedded and Distributed Memory  Approximately 358 Kbits of on-chip RAM distributed between block and distributed memory resources for buffering, FIFOs and state storage.
• I/O Density and Flexibility  Up to 195 I/Os in a 256-ball fpBGA package to support rich peripheral and subsystem interfacing options.
• Dedicated DDR Memory Support  Family-level support for dedicated DDR memory interfaces to simplify system memory integration.
• Clocking and Timing  Family includes multiple PLL resources for clock multiply/divide and phase shifting for system-level clock management.
• Package and Mounting  256-ball fpBGA (17 × 17 mm) surface-mount package suitable for compact board designs.
• Commercial Grade and Compliance  Commercial temperature grade (0 °C to 85 °C) and RoHS compliant.

Typical Applications

• Commercial Embedded Systems  Control, protocol bridging and custom logic acceleration in mid-range embedded products where moderate logic density and on-chip RAM are required.
• Communications and Networking  Interface glue logic, packet processing and protocol adaptation using the device's abundant I/O and embedded memory resources.
• Memory Interface Bridging  Systems requiring DDR memory support can leverage the family-level DDR interface logic to integrate external memory subsystems.
• Prototyping and System Integration  Platform-level designs and proof-of-concept implementations benefiting from configurable logic, PLLs and flexible I/O.

Unique Advantages

• Balanced Mid‑Range Capacity:  Approximately 15,400 logic elements and ~358 Kbits of embedded memory provide a strong fit for designs that outgrow small FPGAs but do not require top-end densities.
• High I/O Count in a Compact Package:  195 I/Os in a 256-ball fpBGA (17 × 17 mm) enables dense connectivity without a large PCB footprint.
• Low-Voltage Core:  Operates from 1.14 V to 1.26 V, aligning with modern low-voltage system architectures.
• System-Level Integration:  On-chip memory, PLLs and family DDR interface support reduce external component count and simplify board-level integration.
• Commercial Reliability and Compliance:  Commercial temperature rating and RoHS compliance support standard commercial product lifecycles and regulatory needs.
• Design Ecosystem:  Part of the LatticeECP/EC family with available design tools and IP flows for efficient implementation and migration within the family.
