LFE2M35E-6F256I

The LFE2M35E-6F256I is an industrial‑grade FPGA from Lattice Semiconductor’s ECP2M family. It combines a dense logic fabric with embedded memory and advanced DSP/SERDES resources for system integration in communications, industrial control and high‑speed interface designs.

Designed for applications that require on‑chip memory, plentiful I/O and deterministic operating range, this 256‑ball fpBGA package supports surface‑mount assembly and operation from –40 °C to 100 °C with a 1.14 V to 1.26 V core supply.

Key Features

• Logic Capacity — 34,000 logic elements to implement complex glue logic, protocol handling and custom processing pipelines.
• Embedded Memory — Approximately 2.15 Mbits of on‑chip RAM for frame buffers, packet buffering and algorithm state storage.
• DSP and Arithmetic — Family sysDSP blocks support high‑performance multiply‑accumulate functions; each block can support one 36×36, four 18×18 or eight 9×9 multipliers (family architecture).
• High‑Speed Serial Interfaces — ECP2M family SERDES supports data rates from 250 Mbps to 3.125 Gbps and up to 16 channels per device, enabling interfaces such as Ethernet and PCI Express (family capability).
• I/O and Standards — 140 user I/Os with programmable I/O buffer support for a wide range of single‑ended and differential standards (family feature set).
• Clock Management — On‑chip PLL/DLL resources for clock multiply/divide and phase/delay adjustments; the family table lists two GPLLs and two DLLs for the ECP2‑35 device class.
• Package & Mounting — 256‑ball fpBGA (256‑FPBGA 17×17) in a surface‑mount form factor for compact board integration.
• Industrial Temperature Range — Rated for –40 °C to 100 °C operation to meet demanding environmental requirements.
• Power — Core voltage range specified at 1.14 V to 1.26 V for predictable power budgeting.
• Compliance — RoHS‑compliant material composition.

Typical Applications

• Telecommunications & Networking — Use embedded SERDES channels and on‑chip memory for packet processing, link aggregation and protocol bridging.
• High‑Speed Interface Bridging — Bridge between high‑speed serial links and parallel backplanes or memory interfaces using the device’s SERDES and ample I/O.
• Industrial Control — Implement deterministic control logic, sensor interfacing and real‑time processing within the industrial temperature range.
• Signal Processing & DSP Acceleration — Offload multiply‑accumulate workloads to sysDSP blocks for algorithms requiring high‑performance arithmetic.

Unique Advantages

• Balanced Integration: Combines 34,000 logic elements with approximately 2.15 Mbits of embedded memory to consolidate multiple functions on a single device and reduce board BOM.
• High‑Speed Serial Capability: Family SERDES support up to 3.125 Gbps and multiple channels enables compact designs for modern serial protocols.
• Industrial Reliability: Specified for –40 °C to 100 °C operation and offered in a 256‑ball fpBGA for robust surface‑mount deployment in harsh environments.
• Flexible I/O: 140 user I/Os with programmable buffer support allow interfacing to a wide range of single‑ended and differential standards (family I/O capabilities).
• Deterministic Clocking: On‑chip PLL/DLL resources provide clock multiplication, division and phase/delay adjustment to simplify timing architectures.
