The 8051 is the name of a big family of microcontrollers. The device which we are going to use along this tutorial is the 39。AT89S5239。 which is a typical 8051 microcontroller manufactured by Atmel?. Note that this part doesn39。t aim to explain the functioning of the different ponents of a 89S52 microcontroller, but rather to give you a general idea of the anization of the chip and the available features, which shall be explained in detail along this tutorial. 8051的名字是一個(gè)大家庭的微控制器。該設(shè)備我們將沿著這教程使用的是 39。 AT89S52 39。這 是一個(gè)典型的 8051微控制器制造商 Atmel ? 。請(qǐng)注意,這部分不打算解釋的運(yùn)作情況不同組成部分的 89S52單片機(jī),而是給你一個(gè)大致的組織芯片和可用的功能,應(yīng)詳細(xì)解釋了沿此教程。 The block diagram provided by Atmel? in their datasheet showing the architecture the 89S52 device can seem very plicated, and since we are going to use the C high level language to program it, a simpler architecture can be represented as the figure . 框圖 ?
