DS89C430

超高速闪存微控制器

DS89C430和DS89C450是当前8051兼容微处理器中性能最高的微处理器。此系列产品具有重新设计的处理器内核,在相同的晶振频率下,执行指令的速度是最初的8051处理器的12倍,典型应用中的速度可提高10倍。在运行于每秒每兆赫百万指令(MIPS)速度下,此系列产品能够在33MHz的最高晶振频率下,达到33 MIPS的运行速度。\n\n DS89C440是DS89C450的32kB版本,但已经停止供货。DS89C450可作为引脚兼容替代产品使用。\n\n • 高速8051架构\n• 每个机器周期一个时钟 \n• DC至33MHz工作频率\n• 单周期指令30ns\n• 可选择的变时间MOVX指令,以访问快速/低速外围器件\n• 触发选择的自动递增/递减双数据指针 \n• 支持四种页面存储器访问模式\n\n\n• 片内存储器 \n• 16kB/64kB闪存\n• 在应用可编程 \n• 通过串口实现在系统可编程 \n• MOVX访问的1kB SRAM\n\n\n• 与80C52兼容\n• 与8051引脚及指令集兼容 \n• 四路双向、8位I/O端口\n• 三个16位定时器/计数器 \n• 256字节暂存RAM\n\n\n• 电源管理模式 \n• 可;
