LFE3-70EA-6LFN484C

The LFE3-70EA-6LFN484C is a Lattice ECP3 family Field Programmable Gate Array (FPGA) in a 484-ball BGA package. It delivers a reconfigurable SRAM-based FPGA fabric with 67,000 logic elements and robust on-chip memory suitable for high-volume, high-speed, cost-sensitive applications.

Built for system integration, the device combines substantial logic capacity, embedded RAM and high pin count I/O to address communications, signal-processing and general-purpose embedded logic tasks while operating within a commercial temperature range.

Key Features

• Logic Capacity — 67,000 logic elements provide significant gate density for complex logic and control functions.
• Embedded Memory — Approximately 4.53 Mbits of on-chip RAM (4,526,080 total RAM bits) for frame buffering, FIFOs and embedded data storage.
• I/O Density — 295 user I/Os support wide parallel interfaces and high pin-count designs in the 484-ball BGA package.
• High-speed SERDES and Interfaces — Family features include embedded SERDES with multi-hundred Mbps to multiple-Gbps capability (family-level support up to 3.2 Gbps) for serial protocols and high-speed links.
• sysDSP and DSP Resources — Family sysDSP slice architecture supports high-performance multiply/accumulate operations for signal processing workloads.
• Flexible Memory and Timing — Multiple embedded block RAM resources, PLLs and DLLs (family-level features) enable flexible clocking and deterministic timing for complex systems.
• Configuration and System Support — Supports SPI boot flash interface, dual-boot images, on-chip oscillator and system-level utilities as described for the ECP3 family.
• Package & Mounting — 484-BBGA (supplier package 484-FPBGA, 23 × 23 mm) in a surface-mount form factor for automated PCB assembly.
• Power & Operating Range — Core supply range of 1.14 V to 1.26 V with commercial operating temperature of 0 °C to 85 °C; RoHS compliant.

Typical Applications

• High-speed serial communications — Use embedded SERDES channels for protocol interfaces such as PCI Express, Ethernet, Serial RapidIO and other high-speed links (family-level support).
• Signal processing and media — Leverage sysDSP slices and embedded RAM for DSP, video pre-processing and real-time data path acceleration.
• Memory interface and buffering — Implement DDR/DDR2/DDR3 controllers and source-synchronous memory interfaces using on-chip memory and dedicated I/O features (family-level functionality).
• Embedded control and glue logic — Replace multi-component glue logic with a single FPGA to simplify board design and consolidate control functions using abundant I/Os and logic resources.

Unique Advantages

• High logic density: 67,000 logic elements enable complex SoC-style integration and feature consolidation.
• Substantial embedded memory: Approximately 4.53 Mbits of RAM reduces external memory needs for buffering and local storage.
• Versatile I/O and package: 295 I/Os in a 484-BBGA (23 × 23 mm) package supports dense interfaces while remaining surface-mount compatible for volume assembly.
• Designed for high-speed links: Family SERDES and pre-engineered source-synchronous support ease implementation of high-bandwidth serial and memory interfaces.
• Commercial temperature and RoHS compliance: Rated 0 °C to 85 °C and RoHS compliant for mainstream electronic products.
• Flexible configuration options: SPI boot, dual-boot images and on-chip oscillator options simplify system bring-up and field updates.
