Cyclone III: Highest-Density Low-Cost FPGA Family
The largest Cyclone® III device family member, EP3C120, is now shipping -- With up to 120,000 logic elements (LEs), 4 Mbits of on-chip memory, and 288 embedded 18 x 18 multipliers, the Cyclone III device family is the highest-density low-cost FPGA family in the industry. All of these high-density features come with very low power consumption.

System Integration
The rich supply of logic, memory and multipliers with extremely low power consumption enable you to use Cyclone III FPGAs in the heart of your cost-sensitive system. This family of FPGAs opens new possibilities for designers of low-cost applications including, but not limited to, H.264 encoder, pico base station, digital television (DTV), and software defined radio (SDR).
