DS80C323

高速/低功耗微控制器; ? 80C32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? 地址64kB ROM和64kB RAM\n\n\n\n\n? 高速架構(gòu)：\n? 4個(gè)時(shí)鐘/機(jī)器周期(8032 = 12)\n\n? DC至33MHz (DS80C320)\n\n? DC至18MHz (DS80C323)\n\n? 121ns內(nèi)的單周期指令\n\n? 完成同等工作的功耗更少\n\n? 雙數(shù)據(jù)指針\n\n? 通過可選的可變長(zhǎng)度MOVX訪問快/慢RAM/外設(shè)\n\n\n\n\n? 高集成度控制器包括：\n? 電源故障復(fù)位\n\n? 可編程看門狗定時(shí)器\n\n? 預(yù)警電源故障中斷\n\n\n\n\n? 兩個(gè)全雙工硬件串行端口\n\n? 總共13個(gè)中斷源，其中6個(gè)為外部中斷源\n\n? 采用40引腳DIP、44引腳PLCC和44引腳TQFP封裝;

DS80C320/DS80C323均為快速的80C31/80C32兼容微控制器。使用重新設(shè)計(jì)的處理器內(nèi)核，避免了浪費(fèi)時(shí)鐘和存儲(chǔ)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(dá)到82.5MHz（約2.5倍）。\n\n DS80C320/DS80C323與標(biāo)準(zhǔn)80C32的所有三種封裝引腳兼容，并提供相同的定時(shí)器/計(jì)數(shù)器、串行端口和I/O端口。簡(jiǎn)而言之，這些器件對(duì)于8051用戶來說非常熟悉，但提供了16位處理器的速度。\n\n 除了更高的速度之外，DS80C320還提供了一些額外特性。其中包括第二個(gè)完整硬件串行端口、七個(gè)附加中斷、可編程看門狗定時(shí)器、電源故障中斷和復(fù)位。該器件還提供雙數(shù)據(jù)指針(DPTR)以加速塊數(shù)據(jù)存儲(chǔ)器移動(dòng)。它還可以將片外數(shù)據(jù)存儲(chǔ)器訪問的速度調(diào)整為2到9個(gè)機(jī)器周期，以便靈活地選擇存儲(chǔ)器和外設(shè)。\n\n DS80C320工作電壓范圍為4.25V至5.5V，非常適合作為現(xiàn)有5V系統(tǒng)的高性能升級(jí)產(chǎn)品。對(duì)于功耗至關(guān)重要的應(yīng)用，DS80C323提供與DS80C320相同的功能集，但工作電壓為2.7V至5.5V。\n\n 設(shè)計(jì)人員必須擁有兩份文檔才能充分使用該器件的所有功能：本數(shù)據(jù)手冊(cè)和《高速微控制器用戶指南》（可在我們的網(wǎng)站www.maximintegrated.com/microcontrollers上獲?。?shù)據(jù)手冊(cè)包含引腳描述、功能概述和電氣規(guī)格，而我們的用戶指南包含有關(guān)器件功能和操作的詳細(xì)信息。\n\n
