LFE5U-25F-6BG256I

The LFE5U-25F-6BG256I is an industrial-grade member of the ECP5 FPGA family providing a balance of logic capacity, on-chip memory and I/O density in a compact 256-LFBGA package. It is built for designs requiring moderate logic resources (24,000 logic elements), a large programmable I/O count (197 I/Os) and approximately 1.03 Mbits of embedded RAM.

Architecturally aligned with the ECP5 family, the device includes family-level features such as programmable I/O cells, SERDES and DDR memory support, flexible clocking and device configuration options, making it suitable for industrial, communications and embedded processing applications that require deterministic temperature and voltage operating ranges.

Key Features

• Core Logic  24,000 logic elements provide capacity for mid-range FPGA implementations and complex glue logic.
• On-chip Memory & DSP  Approximately 1.03 Mbits of embedded memory for buffering, FIFOs and local data storage; device documentation also describes sysDSP slices for arithmetic and signal-processing functions.
• I/O and High-Speed Interfaces  197 programmable I/Os in a variety of configurable modes; family documentation includes SERDES and Physical Coding Sublayer blocks for serialized interfaces and high-speed links.
• Clocking and Timing  Family features include sysCLOCK PLL, clock distribution networks, clock dividers and DDRDLL support to facilitate multi-clock designs and DDR memory timing.
• Memory and DDR Support  ECP5 family-level DDR memory support with DQS grouping and calibrated DQS delay/control blocks for interfacing external DDR memories.
• Configuration & Testability  Device-level configuration options, IEEE 1149.1-compliant boundary scan testability, on-chip oscillator and single-event upset (SEU) support are documented for system integration and reliability.
• Package & Power  256-LFBGA (supplier package: 256-CABGA, 14×14) surface-mount package; recommended voltage supply range is 1.045 V to 1.155 V.
• Industrial Operating Range  Industrial grade with operating temperature from −40 °C to 100 °C and RoHS compliance for regulatory consistency.

Typical Applications

• Industrial Control & Automation  Use the device for control logic, protocol bridging and real-time I/O aggregation where industrial temperature range and a high I/O count are required.
• Communications & Networking  Implementing interface conversion, packet processing and serialized links using the device’s programmable I/O and documented SERDES/PCS capabilities.
• Embedded Processing & Edge Devices  On-chip memory and DSP resources support preprocessing, local buffering and hardware acceleration in edge compute modules and sensor hubs.
• Memory Interfaces & Storage Controllers  DDR memory support and timing blocks enable integration with external DDR components for buffering and data-path implementations.

Unique Advantages

• Balanced logic and I/O density: 24,000 logic elements and 197 I/Os provide the right mix for mid-range FPGA designs that require significant interfacing capability without a large-package footprint.
• Integrated memory for local storage: Approximately 1.03 Mbits of embedded RAM reduces dependence on external memory for many buffering and FIFO needs.
• Industrial-rated operation: Specified operation from −40 °C to 100 °C supports deployment in temperature-demanding environments.
• Compact package: 256-LFBGA (256-CABGA, 14×14) surface-mount package offers a small PCB footprint while maintaining high I/O counts.
• Family-level interface and timing features: ECP5 family architecture includes SERDES, DDR support, PLLs and configurable clock networks to simplify high-speed and multi-clock system design.
• Testability and configuration options: Boundary-scan test support, on-chip oscillator and documented configuration features assist integration and manufacturing validation.
