Following the immensely successful first-generation Cyclone® device family, Altera® Cyclone II FPGAs extend the low-cost FPGA density range to 68,416 logic elements (LEs) and provide up to 622 usable I/O pins and up to 1.1 Mbits of embedded memory. Cyclone II FPGAs are manufactured on 300-mm wafers using TSMC's 90-nm low-k dielectric process to ensure rapid availability and low cost. By minimizing silicon area, Cyclone II devices can support complex digital systems on a single chip at a cost that rivals that of ASICs. Unlike other FPGA vendors who compromise power consumption and performance for low-cost, Altera’s latest generation of low-cost FPGAs—Cyclone II FPGAs, offer 60% higher performance and half the power consumption of competing 90-nm FPGAs. The low cost and optimized feature set of Cyclone II FPGAs make them ideal solutions for a wide array of automotive, consumer, communications, video processing, test and measurement, and other end-market solutions.
