高速/低功耗微控制器

DS80C320/DS80C323均為快速的80C31/80C32兼容微控制器。使用重新設(shè)計的處理器內(nèi)核，避免了浪費時鐘和存儲器周期。因此，在相同的晶體速度下，每條8051指令的執(zhí)行速度比原始內(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)用的速度提高了2.5倍。DS80C320提供33MHz的最大晶體速率，從而使表觀執(zhí)行速度達到82.5MHz（約2.5倍）。\n\n DS80C320/DS80C323與標準80C32的所有三種封裝引腳兼容，并提供相同的定時器/計數(shù)器、串行端口和I/O端口。簡而言之，這些器件對于8051用戶來說非常熟悉，但提供了16位處理器的速度。\n\n ? 80C32兼容\n? 8051引腳和指令集兼容\n\n? 四個8位I/O端口\n\n? 三個16位定時器/計數(shù)器\n\n? 256字節(jié)暫存區(qū)RAM\n\n? 地址64kB ROM和64kB RAM\n\n\n\n\n? 高速架構(gòu)：\n? 4個時鐘/機器周期(8032 = 12)\n\n?

High-Speed/Low-Power Microcontrollers

DETAILED DESCRIPTION The DS80C320/DS80C323 are fast 80C31/80C32-compatible microcontrollers. Wasted clock and memory cycles have been removed using a redesigned processor core. As a result, every 8051 instruction is executed between 1.5 and 3 times faster than the original for the same crystal sp
