LFE3-95E-6FN1156C

The LFE3-95E-6FN1156C is a member of the LatticeECP3 family of reconfigurable SRAM FPGAs from Lattice Semiconductor Corporation. It combines a high logic capacity fabric with embedded DSP resources, multi-gigabit SERDES capability and flexible source-synchronous I/O to address high-speed and high-integration designs.

Designed for commercial applications and manufactured in a 1156-BBGA (35×35 mm) surface-mount package, this device targets high-volume, high-speed, cost-sensitive systems that require significant on-chip logic, memory and I/O density.

Key Features

• Core Capacity — 92,000 logic elements provide substantial programmable logic for mid-to-large FPGA designs.
• Embedded Memory — Approximately 4.52608 Mbits of on-chip RAM (total RAM bits: 4,526,080) for large buffers, state storage and packet/stream handling.
• DSP Resources — Includes 128 18×18 multipliers and sysDSP architecture support for high-performance multiply-accumulate and signal processing functions.
• High-speed SERDES and I/O — In the 1156-FPBGA (35×35) package the device supports up to 12 SERDES channels and 490 user I/Os, enabling high-bandwidth serial links and dense parallel interfaces.
• Programmable I/O Standards — sysI/O buffer supports a wide range of standards including LVTTL, LVCMOS (3.3/2.5/1.8/1.5/1.2), SSTL, HSTL, LVDS, Bus-LVDS, LVPECL, RSDS and MLVDS for interface flexibility.
• Clocking and Timing — Supports up to ten PLLs and two DLLs for flexible clock generation and deskewing across the device.
• Configuration & System Support — Flexible configuration options include SPI boot, dual-boot image support and on-chip soft error detect; system features in the family include IEEE 1149.1/1532 support, reveal logic analyzer and configuration utilities.
• Power, Mounting & Temperature — Core supply 1.14 V to 1.26 V (1.2 V core supply supported in family), surface-mount package, commercial operating temperature 0 °C to 85 °C, RoHS compliant.

Typical Applications

• Networking & Telecom — Multi-gigabit SERDES and high I/O count support interfaces and protocols such as Ethernet, PCI Express and other high-speed links used in network equipment.
• Video & Broadcast — High-speed serial channels and source-synchronous I/O make the device suitable for SMPTE and other broadcast video transport and processing.
• Signal Processing & Embedded Compute — sysDSP slices and abundant 18×18 multipliers enable FIR filters, FFTs and other DSP-intensive tasks.
• Memory Subsystems & Interface Bridging — Flexible I/O standards and dedicated DDR/DDR2/DDR3 support with DQS make the device useful as a memory controller or protocol bridge.

Unique Advantages

• High Logic Integration: 92,000 logic elements reduce external glue logic and enable greater system consolidation on a single device.
• Substantial On‑Chip Memory: Approximately 4.5 Mbits of embedded RAM cuts external memory dependency for buffering and packet handling.
• Powerful DSP Capability: 128 18×18 multipliers and sysDSP architecture accelerate signal-processing functions while keeping data on-chip.
• Flexible High-Speed I/O: Up to 12 SERDES channels and 490 user I/Os in the 1156 package support dense, high-bandwidth system interfaces.
• Robust System Features: Multiple PLLs/DLLs, configuration options and family-level tools (logic analysis and configuration utilities) streamline development and deployment.
• Commercial‑Grade, RoHS Compliant: Designed for commercial temperature ranges and compliant with RoHS requirements for broad market deployment.
