Built on TSMC’s highly successful 90-nm process technology using 300-mm wafers, Cyclone II FPGAs offer higher densities, more features, exceptional performance, and the benefits of programmable logic at ASIC prices. Cyclone II devices offer from 4,608 to 68,416 logic elements (LEs) and are designed with an optimal set of features, including embedded 18 x 18 multipliers, dedicated external memory interface circuitry, 4-kbit embedded memory blocks, phase-locked loops (PLLs), and high-speed differential I/O capabilities. Cyclone II devices extend the reach of FPGAs further into cost-sensitive, high-volume applications, continuing the success of the Cyclone device family. Table 1 outlines the Cyclone II FPGA family's features and availability. Table 1.

This enables the FPGA to be operational in a shorter period of time than a regular Cyclone II device. These devices are distinguished with an “A” designation in the ordering code (e.g., EP2C8AF256I8N). For questions regarding the specification for these parts, refer to the Cyclone II data sheet. For questions regarding the availability of these parts, contact your Altera® representative. The EP2C15 device is only available with the Fast On option as an EP2C15A device. EP2C5A devices are only available in automotive-grade versions.
