南京沁恒电子的ch365资料，CH365 是一个连接PCI总线的通用接口芯片，支持I/O端口映射、存储器映射、扩展ROM 以及中断。CH365 将32 位高速PCI 总线转换为简便易用的类似于ISA 总线的8 位主动并行接口，用于制作低成本的基于PCI 总线的计算机板卡，以及将原先基于ISA 总线的板卡升级到PCI总线上。PCI 总线与其它主流总线相比，速度更快，实时性更好，可控性更佳，所以CH365 适用于高速实时的I/O控制卡、通讯接口卡、数据采集卡、电子盘、扩展ROM 卡等。-Nanjing Qin ch365 constant electronic information, CH365 is a PCI bus connecting the common interface chip to support I / O port mapping, memory mapping, Expansion ROM and disruption. CH365 to 32 high-speed PCI bus converted to simple, easy-to-use similar to the ISA bus eight concurrent access initiative I, for the production of low-cost PCI-based computer Card, and will be based on the original ISA Bus Card upgrade to the PCI Bus. PCI bus with other mainstream compared to faster, better real-time performance, better controllability, So CH365 apply to the high-speed real-time I / O control card, communication interface cards, data acquisition cards, electronic games Expansion ROM cards.
