Description: sim卡的介绍,和读取sim卡的源程序
（1）SIM卡能够储存多少电话号码取决于卡的EEPROM的容量（有2K、4K、8K、16K、32K等容量），若有8KB的存储容量，可供储存以下信息：
*100组电话号码及其对应的性名文字；
*15组短信息（Short Message）；
*25组以上最近拨出的号码；
*4位SIM卡密码（PIN）。
表1：几种主要的SIM卡的结构数据
（2）SIM卡是带有微处理器的芯片卡，内有5个模块，每个模块对应一个功能：CPU（8位）、程序存储器ROM（6-16kbit）、工作存储器RAM（128-256kbit）、数据存储器EEPROM（2-8kbit）和串行通信单元，这5个模块集成在一块集成电路中。SIM卡在与手机连接时，最少需要5个连接线：
*电源（Vcc）

Description: 本程序用于MICROCHIP 24LC64 EEPROM的读写。本程序不使用芯片级联方式，
请将A0，A1，A2 管脚接至低电平。本程序使用IOC6作为SDA，IOC7作为SCL。
程序中的地址空间最大可至64K：24LC00-16-0，24LC01-128-8，24LC02-256-8，
24LC04-512-16，24LC08-1K-16，24LC16-2K-32，24LC32-4K-32，24LC64-8K-32，
24LC128-16K-64，24LC256-32K-64，24LC512-64K-128，读写数据均为8bits。
以上器件的格式为（型号-地址空间-页大小）不同器件的页大小不同，因此页写
程序需作相应修改，其他字节写，随机读以及顺序读程序均相同-This procedure for the MICROCHIP 24LC64 EEPROM read and write. This procedure does not use chips cascade way, please A0, A1, A2 pin to low level access. This procedure used IOC6 as SDA, IOC7 as SCL. Process address space available to the largest 64K: 24LC00-16-0, 24LC01-128-8, 24LC02-256-8, 24LC04-512-16, 24LC08-1K-16, 24LC16-2K-32, 24LC32-4K- 32,24 LC64-8K-32, 24LC128-16K-64, 24LC256-32K-64, 24LC512-64K-128, read and write data are 8bits. The format for the above device (Model- address space- page size) of different devices of different sizes of pages, so page written procedures need to be amended accordingly, and other bytes to write, random read and sequential read are the same procedures

Description: This an example of using I2C to access a serial eeprom with the nerdkit. The eeprom used is the 24LC256 with a capacity of 32k bytes. I m not sure yet of a real project where I will use it but maybe archiving data on a weather station so it can be uploaded time to time. Or perhaps a min/max thermomitor that saves temp every minute and later can be uploaded for analysis. I d like to know about your projects that will make use of external eeproms.-This is an example of using I2C to access a serial eeprom with the nerdkit.
