51單片機的外形封裝雙列直插的DIP40貼片PLCC44貼片QFP4440只引腳雙列封裝（直插DIP）雙列直插式，是一種傳統(tǒng)的封裝形式，管腳間距大，占用電路板面積大，便于自制電路板，方便維修。適用學(xué)校，培訓(xùn)機構(gòu)，但是封裝體積大，電路板制作成本高，商品里應(yīng)用較少。40只引腳雙列封裝（直插DIP）44引腳方形封裝方式(貼片PLCC)PLCC為方形貼片形式的，可以直接應(yīng)用在電路板上，不必鉆孔，研發(fā)實驗教學(xué)是可以利用插座，縮短開發(fā)生產(chǎn)周期。44引腳方形封裝方式(貼片PLCC)>>>>44引腳方形封裝方式(貼片PQFP)所占面積更小，成本低，常用于管腳比較多的單片機芯片。44引腳方形封裝方式(貼片PQFP)>>>>8051單片機的信號引腳及功能GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCEAALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51GNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516171819204038393736353433323130292827262524232221AT89S51EAEAGNDRSTXTAL1XTAL2P1.1P1.2P1.3P1.4P1.5P1.6P1.7P1.0P3.1P3.2P3.3P3.4P3.5P3.6P3.7P3.0VCCALEPSENP0.1P0.2P0.3P0.4P0.5P0.6P0.7P0.0P2.6P2.5P2.4P2.3P2.2P2.1P2.0P2.7A0A1A2A3A4A5A6A7A15A14A13A12A11A9A8A10/D0/D1/D2/D3/D4/D5/D6/D7電源訪問外部程序存儲器控制信號線地址鎖存允許信號線訪問外部程序存儲器讀選通信號線地RXD/TXD/INT0/INT1/T0/T1/WR/RD/時鐘信號線1時鐘信號線2復(fù)位信號線12345678910111213141516
