LFEC33E-5FN484C

The LFEC33E-5FN484C is a commercial-grade FPGA from Lattice Semiconductor’s ECP/EC family designed for mainstream, cost-sensitive applications. It provides a balanced combination of logic density, on-chip memory and flexible I/O in a compact 484-ball BGA package.

This device targets applications that require substantial logic resources and high I/O counts while operating from a low-voltage supply. It is suitable for designs that benefit from family-level tool and IP support outlined in Lattice’s documentation.

Key Features

• Logic Capacity — 32,800 logic elements, providing significant programmable logic resources for combinational and sequential designs.
• On-chip Memory — 434,176 total RAM bits (approximately 434 Kbits) of embedded and distributed memory for buffering, FIFOs and small data stores.
• I/O Density — 360 user I/Os to support multiple parallel interfaces and board-level connectivity.
• Package & Mounting — 484-ball BBGA (484-FPBGA, 23 × 23 mm) in a surface-mount form factor for compact board layouts.
• Power — Nominal 1.2 V supply with a supported operating range of 1.14 V to 1.26 V.
• Operating Temperature — Commercial temperature rating from 0 °C to 85 °C.
• Clocking — Family-level support for up to four analog PLLs per device for clock management and phase control.
• System & Development Support — Part of the LatticeECP/EC family with documented support for the ispLEVER design tool suite and available ispLeverCORE IP modules.
• Compliance — RoHS compliant.

Typical Applications

• Embedded Control and Glue Logic — Use the LFEC33E-5FN484C to consolidate multiple discrete logic functions, interface controllers and protocol bridges on a single device.
• Memory Interface and Buffering — Implement DDR/parallel memory interfaces and data buffering using the device’s embedded memory resources and high I/O count.
• Communications and Networking — Support protocol agnostic front-end processing, packet handling, and parallel I/O aggregation where moderate logic density and many I/Os are required.
• Consumer and Industrial Electronics — Deploy as the programmable logic element for feature-rich consumer or commercial products that operate within a 0 °C to 85 °C range and standard supply voltages.

Unique Advantages

• High Logic Density: 32,800 logic elements enable complex designs without resorting to larger, more costly devices.
• Substantial Embedded Memory: 434,176 bits of on-chip RAM reduce external memory dependence for many buffering and state-storage needs.
• Extensive I/O Count: 360 I/Os allow extensive board-level interfacing and parallel connectivity, simplifying board routing for multi-interface systems.
• Compact BGA Package: The 484-ball FPBGA (23 × 23 mm) provides a high I/O footprint in a space-efficient package suitable for compact system designs.
• Low-Voltage Operation: Designed around a nominal 1.2 V supply (operating range 1.14–1.26 V), supporting modern low-voltage system architectures.
• Toolchain and IP Ecosystem: Supported by Lattice’s ispLEVER tool suite and family IP, accelerating development and reducing integration time.
