Description: 62256在单片机上的应用,C语言源码,Keil uVision3工程文件,附原理图及说明学习文档
62256简介:
62系列是最常用的单片机系统扩展RAM元器件,其类型有6216、6232、6264、62128、62256或62512等多种,62后面的数字表示此元器件中可以存储的位(单位:千bit),我们通常的说法是将此值除以8,比如62256将256除以8,我们一般称之为32K的RAM。
如果学习过二进制就可以知道,区分两个字节需要一根地址线就可以:0或者1;而区分四个字节需要2根地址线;区分八个字节需要三根地址线…..以此类推,我们可以计算出要区分32K的RAM区,需要15根地址线,也就是器件上面的A0-A14管脚用于确定唯一的一个字节内容。
我们现在学习的51单片机是8位的,所以必须用两个IO口来联接这个RAM器件,通常我们用P0(低字节)和P2(高字节)两个端口来确定此器件的地址,而P0口是51单片机标准的总线口,是地址线和数据线复用的,所以与62256联接时需要加一片锁存器来锁存地址。即先将地址送到锁存器(通常用74HC373)中,然后P0口空闲下来后开始接收或发送数据至62256。

Description: 此示例包括工作四功能的计算器
基于8051单片机的。该电路还演示了
行业标准的字母数字液晶显示模块,
与通用键盘模型。正如你所看到的,
后者可以模拟任何设计矩阵键盘
像你在乎吸引太多的现实主义。
同样有趣的是电路使用外部存储器的事实,
与8051和6264的RAM芯片之间的相互作用
模拟得出的。
两个8051和RAM芯片支持弹出窗口
可以选择从调试菜单一旦
调试会话正在进行。-This sample comprises a working four function calculator
based an 8051 microcontroller. The circuit also demonstrates
the industry standard alphanumeric LCD display model,
and the universal keypad model. As you can see,
the latter allows you to simulate any design of matrix keypad
with as much realism as you care to draw.
Also of interest is the fact the circuit uses external memory,
and the interaction between the 8051 and the 6264 RAM chip
is simulated as drawn.
Both the 8051 and the RAM chip support popup windows
which can be selected from the Debug menu once
a debugging session is under way.
