LFE3-35EA-7LFTN256C

The LFE3-35EA-7LFTN256C is a Lattice Semiconductor ECP3 family field programmable gate array (FPGA) in a 256‑ball FTBGA package. It delivers 33,000 logic elements and flexible on-chip memory in a compact, surface‑mount package for commercial applications requiring high integration and low‑voltage operation.

Designed for mid‑range logic and high‑speed I/O integration, this device targets applications that need a balance of DSP capability, embedded memory and multi‑lane serial interfaces while operating within a 1.14 V to 1.26 V core supply range and a 0 °C to 85 °C commercial temperature window.

Key Features

• Core Logic — 33,000 logic elements provide substantial LUT capacity for mid‑range FPGA designs and system integration.
• Embedded Memory — Approximately 1.36 Mbits of on‑chip RAM (total RAM bits: 1,358,848) for frame buffering, FIFOs and state storage.
• High‑Speed I/O — Up to 133 user I/Os supported in the 256‑FTBGA (17×17 mm) package, enabling broad interface flexibility.
• SERDES Capability — Supports up to 4 SERDES channels (quad) in the 256‑FTBGA package for multi‑lane serial protocols and high‑speed links.
• DSP and Arithmetic — ECP3 family sysDSP architecture (as described in the family datasheet) for multiply‑accumulate and high‑performance arithmetic operations.
• Flexible Configuration & System Support — Family features include dual‑boot images, SPI boot flash interface and on‑chip oscillator; system utilities and debug support are provided for development.
• Package & Mounting — 256‑BGA (256‑FTBGA, 17×17 mm) surface‑mount package for compact board-level integration.
• Power & Temperature — Core voltage range 1.14 V to 1.26 V; commercial operating temperature range 0 °C to 85 °C.
• Regulatory — RoHS compliant, supporting lead‑free manufacturing processes.

Typical Applications

• High‑Speed Serial Connectivity — Implement multi‑lane SERDES links such as PCI Express or Ethernet physical interfaces using available quad SERDES channels and abundant I/Os.
• Video and Broadcast Processing — Use the device’s DSP resources and embedded memory for video frame buffering, formatting and SMPTE‑3G interface handling.
• Communications & Radio Infrastructure — Deployable in CPRI and other telecom link designs that require deterministic DSP and serial link support.
• Industrial and Commercial Control — Suitable for mid‑range control, sensor aggregation and protocol bridging within the specified commercial temperature range.

Unique Advantages

• Balanced Logic and Memory: 33,000 logic elements combined with approximately 1.36 Mbits of embedded memory enables complex control and buffering without immediate need for external RAM.
• Compact, High‑I/O Package: 256‑FTBGA (17×17 mm) offers 133 I/Os and quad SERDES capability in a space‑efficient footprint for dense PCBs.
• Low‑Voltage Core: Operates within a narrow 1.14 V–1.26 V supply window to match modern low‑voltage power architectures.
• Commercial‑Grade Reliability: Rated for 0 °C to 85 °C operation and RoHS compliant for production environments targeting consumer and commercial systems.
• System Development Support: Family‑level features include flexible configuration options and on‑chip utilities to streamline prototyping and field updates.
