LatticeECP & EC Low-Cost FPGAs

The LatticeECP^TM (EConomy Plus) FPGA concept combines an efficient FPGA fabric with high-speed dedicated functions. Lattice's first generation FPGA to implement this approach, the LatticeECP-DSP (EConomy Plus DSP) family, provides dedicated high-performance DSP blocks on-chip. The LatticeEC^TM (EConomy) FPGA supports all the general-purpose features of LatticeECP devices without dedicated function blocks to achieve even lower cost.

The LatticeECP-DSP FPGA is ideal for use in applications in which cost-effective DSP functionality is needed. Such applications include software defined radio, wireless communications, military applications and video processing equipment. The LatticeEC FPGA is ideal for general non-DSP applications such as low-cost networking, blade servers, network access equipment, consumer electronics, industrial, medical and automotive applications.
