DS87C520	EPROM/ROM High-Speed Micro DESCRIPTION The DS87C520/DS83C520 EPROM/ROM high-speed microcontrollers are fast 8051-compatible microcontrollers. They feature a redesigned processor core without wasted clock and memory cycles. As a result, the devices execute every 8051 instruction between 1.5 and 3 times faster than the origi	DALLAS	DALLAS
DS87C520	EPROM/ROM高速微控制器 DS87C520/DS83C520 EPROM/ROM高速微控制器均为快速的8051兼容微控制器。它们采用重新设计的处理器内核，不会浪费时钟和存储器周期。因此，在相同的晶体速度下，这些器件执行每条8051指令的速度比原始内核快1.5到3倍。使用相同的代码和相同的晶体，典型应用的速度将提高2.5倍。DS87C520/DS83C520提供33MHz的最大晶体速度，从而使表观执行速度达到82.5MHz（约2.5倍）。\n\n DS87C520/DS83C520与标准8051的所有三种封装引脚兼容，并包括三个定时器/计数器、串行端口和四个8位I/O端口等标准资源。它们具有16kB EPROM • 80C52兼容\n• 8051引脚和指令集兼容\n\n• 四个8位I/O端口\n\n• 三个16位定时器/计数器\n\n• 256字节暂存区RAM\n\n\n\n\n• 大容量片内存储器\n• 16kB程序存储器\n\n• 用于MOVX的1kB额外片内SRAM\n\n\n\n\n• ROMSIZE特性\n• 选择0至16kB范围内的内部ROM大小\n\n• 支持访问整个外部存储器映射\n\n• 可通过软件动态调节\n\n• 可用作外部闪存的引导块\n\n\n\n\n• 高速架构\n• 4个时钟/机器周期(8051 = 12)\n\n• 运行DC至33MHz时钟速率\n\n• 121ns内的;	AD 亚德诺	AD
