Description

The LFE5U-45F-7BG256I is a member of Lattice Semiconductor's ECP5 FPGA family, designed for low-power, high-performance applications. Key features include:
- 45K LUTs (Look-Up Tables) for flexible logic implementation.
- Ultra-low power consumption, ideal for portable/battery-powered devices.
- 7BG256I package: 256-ball caBGA (chip array Ball Grid Array) with industrial-grade temperature support.
- High-speed SerDes (up to 3.2 Gbps) and DDR3 memory support.
- Embedded DSP blocks for signal processing.
Common applications include embedded vision, communications, and IoT due to its balance of power efficiency and performance. The ECP5 series is also popular in open-source FPGA toolchains (e.g., Yosys + nextpnr).
For detailed specs, refer to Lattice’s ECP5 datasheet or FPGA-Tech.com.
