LFE2-20SE-5F256C

The LFE2-20SE-5F256C is an ECP2-series Field Programmable Gate Array from Lattice Semiconductor, delivered in a 256-ball fpBGA (17 × 17 mm) package for surface-mount assembly. This device provides approximately 21,000 logic elements and extensive I/O capability, targeting mid-density FPGA applications that require flexible logic, embedded memory and on-chip DSP resources.

With an operating supply range of 1.14 V to 1.26 V and a commercial temperature rating (0 °C to 85 °C), the part is suited for a wide range of commercial embedded designs where board-level integration, deterministic I/O counts and on-chip memory are required.

Key Features

• FPGA Core  Approximately 21,000 logic elements (logic cells) for implementing combinational and sequential logic, state machines and glue logic.
• Embedded Memory  Approximately 282,624 bits of on-chip RAM for frame buffers, FIFOs and small data stores.
• DSP Resources  Family-level sysDSP resources and dedicated multipliers are provided in the ECP2-20 variant to accelerate arithmetic and signal-processing tasks.
• I/O Density and Flexibility  193 general-purpose I/Os with programmable sysI/O buffer support for a broad set of I/O standards and source-synchronous interfaces.
• Clocking Resources  Device-level clock management includes general-purpose PLLs and DLLs as indicated for the ECP2-20 family, enabling flexible clock multiplication, division and phase adjustment.
• Power  Operates from a nominal low-voltage core supply in the range 1.14 V to 1.26 V.
• Package & Mounting  256-ball fpBGA (17 × 17 mm) supplier device package, surface-mount mounting type suitable for compact board designs.
• Temperature & Grade  Commercial grade with operating temperature range 0 °C to 85 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Embedded Control  Implements custom control logic, protocol handling and glue logic for commercial embedded systems that require flexible programmable logic.
• Signal Processing  Uses on-chip sysDSP blocks and multipliers for acceleration of arithmetic-intensive tasks such as filtering, transforms and fixed-point processing.
• Interface Bridging  Provides a compact solution for bridging parallel and serial interfaces where up to 193 I/Os and programmable I/O standards are needed.
• Memory Interfacing  Uses embedded RAM and dedicated memory interface features for buffering, packet handling or temporary storage in system designs.

Unique Advantages

• Balanced Logic and Memory Mix:  Approximately 21,000 logic elements paired with ~282 Kbits of on-chip RAM supports mid-density designs without extensive external memory.
• High I/O Count in a Compact Package:  193 I/Os in a 256-ball fpBGA (17 × 17 mm) form factor maximizes routing density for small-footprint boards.
• Flexible Clocking:  Integrated PLL/DLL clock resources (as specified for the ECP2-20 family) simplify multi-clock domain designs and timing management.
• Commercial-Grade Reliability:  Designed for 0 °C to 85 °C operation with surface-mount package compatibility for standard commercial production environments.
• Environmentally Compliant:  RoHS compliance supports regulatory and manufacturing requirements for lead-free assembly.
• Supported Design Flow:  Part of the Lattice ECP2 family, supported by the family design documentation and tools referenced for ECP2 devices.
