描述P89C660/662/664/668單片機(jī)內(nèi)帶6KB/32KB/64KB/64KB Flash存儲(chǔ)器,該存儲(chǔ)器既可并行編程也可以串行在系統(tǒng)編程(ISP).在實(shí)際的成型產(chǎn)品中,可通過(guò)ISP升級(jí)用戶程序. 在Boot ROM程序中可通過(guò)一個(gè)默認(rèn)的串行下載器(UART)對(duì)Flash存儲(chǔ)器作ISP編程,而在Flash代碼區(qū)中并不需要有調(diào)用下載器的代碼,用戶程序可通過(guò)調(diào)用在Boot ROM中的標(biāo)準(zhǔn)子程對(duì)Flash存儲(chǔ)器擦寫和再編程(即IAP). 該器件在6個(gè)時(shí)鐘周期內(nèi)執(zhí)行一條指令,是傳統(tǒng)的80C51的兩倍.一個(gè)OTP結(jié)構(gòu)位讓用戶選擇傳統(tǒng)的12個(gè)時(shí)鐘周期. 該器件用advanced CMOS工藝制造,是80C51單片機(jī)家族的衍生品.其指令集和80C51相同. 該器件有四個(gè)8位I/O口,三個(gè)16位定時(shí)器/事件計(jì)數(shù)器,多中斷源,四個(gè)優(yōu)選級(jí),可嵌套中斷結(jié)構(gòu),一個(gè)增強(qiáng)型UART和片內(nèi)振蕩器以及時(shí)序電路. P89C660/662/664/668新增特性使其成為一個(gè)功能強(qiáng)大的單片機(jī),為某些應(yīng)用提供PWM,高速的I/O和加/減計(jì)數(shù),如汽車控制.

我們?cè)谧鲆粋€(gè)單片機(jī)系統(tǒng)時(shí)，常常會(huì)遇到這樣那樣的數(shù)據(jù)采集，在這些被采集的數(shù)據(jù)中，大部分可以通過(guò)我們的I/O口擴(kuò)展接口電路直接得到，由于51單片機(jī)大部分不帶AD轉(zhuǎn)換器，所以模擬量的采集就必須靠A/D或V/F實(shí)現(xiàn)。下現(xiàn)我們就來(lái)了解一下AD0809與51單片機(jī)的接口及其程序設(shè)計(jì)。
