Product Summary

The LFEC3E3FN256C is a 1.2V FPGA. It is optimized to deliver mainstream FPGA features at low cost. For maximum performance and value, the LatticeECP (EConomy Plus) FPGA concept combines an efficient FPGA fabric with high-speed dedicated functions. The LFEC3E3FN256C is designed from the outset with low cost in mind, contains all the critical FPGA elements: LUT-based logic, distributed and embedded memory, PLLs and support for mainstream I/Os. The LFEC3E3FN256C provides many pre-designed IP (Intellectual Property) ispLeverCORE modules for the LatticeECP/EC family.
