[单片机开发] 62256

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。

[单片机开发] MSP430F149_AT24C02

本程序使用MSP430F149控制IIC总线EEProm AT24C02;MCU的通用输入输出(GPIO)端口P1.2、P1.3 与AT24C02 的SCL、SDA端口相连接构成I2C总线,因为MSP430F149 内部没有专用的I2C接口电路,所以只能用IO端口来模拟I2C时序从而实现对EEPROM的读写操作。从图 3.3 中我们可以看到EEPROM地址选择端口A0~A2 都外接低电平,所以进行I2C通信时,EEPROM的从机地址是唯一的,即A0~A2 所对应的地址控制位均为 0。 因为AT24C0X(X=1,2,4,8,16)系列芯片的管脚是兼容的,所以用户也可以自行更换其他型号的芯片,无需改动任何硬件结构,只需注意器件地址和存储空间寻址模式的变化,相应地修改软件程序即可。 (2008-05-23, C/C++, 40KB, 下载231次)

[单片机开发] 62256

MSC-51系列单片机内有128B或256B的RAM数据存储器,对一般应用场合,内部 RAM可以满 足系统对数据存储器的要求,但对需要大容量数据缓冲器的应用系统(如数据采集系统),仅片内的RAM存储器往往不够用,这种情况下,就需要在单片机外部扩展数据存储器。 MSC-51与外部数据存储器的一般连接方法:外部数据存储器的高8位地址由P2口提供,低8位地址线接地址锁存器的输出端。外部RAM的读、写控制信号分别接MCS-51的 、 。外部RAM的片选信号可由P2口未用的地址线的剩余口线以线选方式或译码方式提供。 随机存贮芯片(RAM)HM62256的存贮量为32KB,地址线有(A0~A14),是单片机应用系统中最常见的数据存储器
