          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

          EPROM/ROM高速微控制器

          DS87C520/DS83C520 EPROM/ROM高速微控制器均為快速的8051兼容微控制器。它們采用重新設(shè)計(jì)的處理器內(nèi)核,不會(huì)浪費(fèi)時(shí)鐘和存儲(chǔ)器周期。因此,在相同的晶體速度下,這些器件執(zhí)行每條8051指令的速度比原始內(nèi)核快1.5到3倍。使用相同的代碼和相同的晶體,典型應(yīng)用的速度將提高2.5倍。DS87C520/DS83C520提供33MHz的最大晶體速度,從而使表觀執(zhí)行速度達(dá)到82.5MHz(約2.5倍)。\n\n DS87C520/DS83C520與標(biāo)準(zhǔn)8051的所有三種封裝引腳兼容,并包括三個(gè)定時(shí)器/計(jì)數(shù)器、串行端口和四個(gè)8位I/O端口等標(biāo)準(zhǔn)資源。它們具有16kB EPROM ? 80C52兼容\n? 8051引腳和指令集兼容\n\n? 四個(gè)8位I/O端口\n\n? 三個(gè)16位定時(shí)器/計(jì)數(shù)器\n\n? 256字節(jié)暫存區(qū)RAM\n\n\n\n\n? 大容量片內(nèi)存儲(chǔ)器\n? 16kB程序存儲(chǔ)器\n\n? 用于MOVX的1kB額外片內(nèi)SRAM\n\n\n\n\n?
