Altera Cyclone® II FPGA
Altera Cyclone® II 90nm FPGA 的设计初衷在于实现低功耗,并向大批量、成本敏感型应用提供用户定制的多种功能。Cyclone II FPGA 可以与 ASIC 相媲美的成本提供更好的性能和更低的功耗。Cyclone II FPGA 将低成本 FPGA 的密度范围扩展至68,416个逻辑单元(LE),共有622个可用I/O引脚,并配有1.1Mbit嵌入式存储器。为确保快速可用性和降低成本,Cyclone II FPGA 采用了300mm晶圆和 TSMC 的90nm低k介电质工艺。通过减小硅片面积,Cyclone II 器件可以与 ASIC 相媲美的成本在单一芯片上实现复杂的数字系统。与竞争对手的 90nm FPGA 相比,Altera Cyclone II FPGA 性能高出了60%,功耗降低了一半。Cyclone II FPGA 具有成本最低和性能经过优化等特性,特别适用于汽车、消费电子、通信、视频处理、测试和测量以及其他终端市场解决方案等各种应用场合。特性
