LFE2-20SE-6QN208I

The LFE2-20SE-6QN208I is an industrial-grade FPGA from Lattice Semiconductor’s ECP2 family, delivered in a 208-pin BFQFP package. It provides a mid-range fabric with 21,000 logic elements, flexible on-chip memory and a rich I/O complement for embedded control, communications and signal-processing applications.

This device targets designs that require compact board-level integration and deterministic operation across an extended temperature range, while leveraging family-level features such as embedded DSP resources and programmable clocking blocks described in the Lattice ECP2 series documentation.

Key Features

• Core Logic — 21,000 logic elements for implementing medium-complexity custom logic and control functions.
• Programmable DSP Resources — ECP2 family sysDSP blocks are available for high-performance multiply-accumulate operations (ECP2-20 family-level configuration: 7 sysDSP blocks with 28 18×18 multipliers).
• Embedded Memory — Total on-chip RAM of 282,624 bits (approximately 276 Kbits) to support buffers, state machines and local data storage.
• I/O and Interfaces — 131 user I/Os provided in the 208-pin BFQFP package to connect peripherals, sensors and external logic; the device supports a wide range of programmable I/O standards at the family level.
• Clocking — Family-level clock management includes general-purpose PLLs and DLLs (ECP2-20 family-level: 2 GPLLs and 2 DLLs) for flexible clocking, phase and frequency management.
• Power — Core supply operating range: 1.14 V to 1.26 V, enabling standard low-voltage FPGA core operation.
• Package & Mounting — 208-BFQFP package case; supplier package referenced as 208-PQFP (28×28 mm). Surface-mount mounting type simplifies PCB assembly.
• Industrial Temperature Rating — Specified operating range from −40 °C to 100 °C for reliable operation in industrial environments.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Industrial Control and Automation — Implement deterministic I/O handling, custom control logic and local signal processing across an extended temperature range.
• Signal Processing and Embedded DSP — Leverage sysDSP blocks and on-chip RAM for filtering, accumulation and other processing tasks in compact hardware implementations.
• Interface Bridging and Custom Peripherals — Use the 131 I/Os and flexible I/O standards to bridge sensors, memory interfaces and legacy buses on a single FPGA fabric.
• Communications and Networking Modules — Implement protocol adaptors, timing/clocking functions and packet preprocessing using the FPGA fabric and available clock-management resources.

Unique Advantages

• Balanced mid-range logic capacity: 21,000 logic elements provide a practical balance of density and cost for medium-complexity designs.
• On-chip DSP and multiplier resources: Family-level sysDSP blocks and multiple 18×18 multipliers enable efficient hardware acceleration of arithmetic-intensive tasks.
• Extended operating temperature: −40 °C to 100 °C rating supports deployment in industrial and temperature-challenging environments.
• Flexible clocking: Multiple PLL/DLL resources at the family level simplify clock distribution and phase adjustments for high-reliability systems.
• Compact, assembly-ready package: 208-pin BFQFP surface-mount package suits space-constrained PCBs while providing 131 I/Os for system connectivity.
• Industry-standard compliance: RoHS compliance supports use in regulated manufacturing environments.
