LFEC15E-3F484C

The LFEC15E-3F484C is a Lattice EC family FPGA optimized to deliver mainstream FPGA features and low-cost integration for commercial applications. It combines a mid-range logic fabric with on-chip memory, flexible I/O and multi-PLL clocking to support system glue logic, high-density I/O interfacing and DDR memory support in cost-sensitive designs.

Key Features

• Logic Capacity — 15,400 logic elements providing a mid-range FPGA fabric for implementing control, glue logic and moderate complexity designs.
• Fabric Resources — 1,920 PFUs/PFFs as defined for this device family, enabling structured placement and routing for predictable design scaling.
• On-chip Memory — Approximately 358 Kbits of embedded RAM to support buffers, FIFOs and small local data storage.
• I/O Density and Flexibility — 352 user I/Os with programmable sysI/O buffer support for a wide range of interface standards as provided by the family (LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS, Bus-LVDS, LVPECL, RSDS).
• Clocking — Up to four analog PLLs per device for clock multiplication, division and phase shifting.
• Dedicated Memory Interface — Family-level support for dedicated DDR memory interfaces (up to DDR400) for systems requiring external DRAM.
• Package and Mounting — 484-ball BGA package (supplier package: 484-FPBGA, 23 × 23 mm) in a surface-mount form factor suitable for compact, high-I/O PCBs.
• Power and Temperature — Nominal supply range 1.14 V to 1.26 V; commercial operating temperature 0 °C to 85 °C.
• Standards and Tools — IEEE 1149.1 boundary-scan support and ispLEVER design tool ecosystem with pre-designed IP modules for accelerated development.
• Compliance — RoHS compliant.

Typical Applications

• System Glue Logic and Control: Implement interface bridging, protocol conversion and control logic where mid-range logic resources and many I/Os are required.
• Memory Interface Controllers: Use the device’s dedicated DDR memory support to implement DDR400-compatible interfaces for external DRAM subsystems.
• High-Density I/O Systems: Deploy in communications and embedded platforms that require dozens to hundreds of programmable I/Os for sensors, transceivers and peripheral interfaces.
• Cost-Sensitive Commercial Products: Integrate into products that prioritize mainstream FPGA functionality and low overall BOM cost within a commercial temperature range.

Unique Advantages

• Balanced Integration: A combination of ~15,400 logic elements and ~358 Kbits of on-chip RAM enables compact implementations without extensive external logic.
• High I/O Count in a Compact Package: 352 I/Os in a 484-ball BGA (23 × 23 mm) reduce board routing complexity while supporting dense system designs.
• Flexible Interface Support: Family-level programmable I/O options support a broad range of signaling standards to simplify multi-protocol designs.
• Clocking Versatility: Up to four PLLs provide on-device clock management for multi-domain systems and timing optimization.
• Design Ecosystem: Compatibility with ispLEVER tool flow and available ispLeverCORE IP helps accelerate development and reduce time-to-market.
• Regulatory and Assembly Ready: Surface-mount BGA packaging and RoHS compliance facilitate modern PCB assembly and regulatory conformity for commercial products.
