TLC549是一種采用8位逐次逼近式工作的A/D轉(zhuǎn)換器。內(nèi)部包含系統(tǒng)時(shí)鐘、采樣和保持、8位A/D轉(zhuǎn)換器、數(shù)據(jù)寄存器以及控制邏輯電路。TLC549每25uS重復(fù)一次“輸入—轉(zhuǎn)換—輸出”。器件有兩個(gè)控制輸入：I/O CLOCK和片選（CS）。 內(nèi)部系統(tǒng)時(shí)鐘和I/O CLOCK可獨(dú)立使用。應(yīng)用電路的設(shè)計(jì)只需利用I/O時(shí)鐘啟動(dòng)轉(zhuǎn)換或讀出轉(zhuǎn)換結(jié)果。當(dāng)CS為高電平時(shí)，DATA OUT處于高阻態(tài)且I/O時(shí)鐘被禁止。

在做一個(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)我們就來了解一下AD0809與51 單 片機(jī)的接口及其程序設(shè)計(jì)。

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
