EEPROM电路设计规范
EEPROM电路设计规范1范围本标准对室内EEPROM电路的电路原理，各器件的参数计算选择，相关技术要求和实际使用中的有关问题进行了阐述。
本标准适用于家用空调国内事业部空调产品的EEPROM电路的设计。
2定义无3总述家用空调的机型比较多，同一款机型经常会共用一套主控板，由于各种机型的参数不一样，所以把该机型的参数写入EEPROM内部，上电时读入主芯片，以及开机工作时写入数据。
具体用途可参考“EEPROM读写程序设计指引”。
4EEPROM电路设计4.1电路原理图图1 EEPROM电路4.2工作原理简介如图1，主芯片通过SCL与SDA端口对EEPROM数据进行读写。
芯片24C04介绍：图2 24C04芯片管脚图1~3脚：EEPROM地址选择；单个EEPROM时：1~3脚接地；2个EEPROM时：如下图3，IC16第1，第3管脚接地，第2管脚接VCC，IC17第2，第3管脚接地，第1管脚接VCC；图3 2个EEPROM电路（变频室外341EEPROM电路）4脚：电源地端口；5脚：与主芯片通信数据端口；6脚：与主芯片通信时钟端口；7脚：EEPROM写入控制端口，当为“1”时芯片写入禁止，硬件电路上直接接到VCC端；当为“0”时芯片写入使能，硬件电路上直接接地，对于MCU程序自带掉电记忆功能机型需要注意；8脚：电源输入端口，工作电压：ST：2.5v~5.5v；ATMEL：1.8V~5.5v，具体参考芯片功能书。
4.3各元件的作用及元件的选择EEPROM选择：由于变频机室外同时使用2个到EEPROM，必须对EEPROM地址进行设置，所以要求24C04芯片的地址端可供设置，则必须使用ST、A TMEL品牌；上拉电阻R9，R10：如果主芯片对SCL与SDA是开漏输出口，则必须接上拉，上拉电阻阻值根据主芯片可承受的灌电流而定，一般可选用1/6W，10K欧的碳膜电阻或者0805封装的贴片电阻，精度5%以上；室外板341电路EEPROM可选用1/6W，1K欧的碳膜电阻或者0805封装的贴片电阻，精度5%以上；如果主芯片不是使用开漏输出口，则R9，R10可免去；限流电阻R6，R7：由于SCL与SDA上拉高电平，为防止大电流灌入主芯片，故接小电阻限流。
EEPROM
嵌入式系统中EEPROM文件系统的设计与实现彭晓锋北京邮电大学电信工程学院，北京（100876）摘要：AT24CXX系列EEPROM在嵌入式领域有着广泛的运用。
本文参考微机文件系统的原理实现能兼容AT24C08-AT24C1024的简单文件系统，实验结果证明本系统高效可行。
关键词：EEPROM, 文件系统，嵌入式1．引言随着大量嵌入式设备的出现，在嵌入式系统中用于存储数据的EEPROM因其简单、方便、可靠的性能和低廉的价格而被广为使用。
当今社会嵌入式系统无所不在，各种嵌入式设备品种繁多，差别巨大。
因此各公司也推出多种不同容量不同型号的EEPROM适应多样的市场应用。
人们一方面希望能像管理大容量存储器（如硬盘，FLASH等）中数据一样简单便捷的操作EEPROM中的数据（包括打开、关闭、读写文件等），同时也希望这种文件系统能兼容不同容量、型号，具有较强的通用性。
而对于采用两线IIC总线读写方式[1]的EEPROM来说，无法使用类似与FLASH所支持的TFFS之类的文件系统，本文参照上述思想，实现了一种能兼容AT24C08-AT24C1024类似于文件系统的用于管理EEPROM中数据的方法，并在实践项目中得到良好运用。
2．AT24CXX系列EEPROM简介AT24CXX系列是ATMEL公司生产的串行电可擦的可编程存储器，它采用8引脚封装，具有可掉电记忆，结构紧凑、存储容量大等特点，可以在2线总线上并接多片芯片，适用于具有大容量数据存储要求的嵌入式系统[2]。
ⅰ）封装及管脚说明AT24C08-AT24C1024的封装如图1所示（对不同型号A0-A2相应改为NC,详见表1），各引脚的功能如下：⑴ A0、A1、A2：器件地址(device address)。
IIC串行总线需连接多个EEPROM芯片时，可用A0、A1、A2来区分各芯片,悬空时为0。
⑵ SDA：I2C 串行数据。

EEPROM存储芯片24C02
EEPROM存储芯⽚24C021、24C02简介 24C02是⼀个2Kbit的串⾏EEPROM存储芯⽚，可存储256个字节数据。
⼯作电压范围为1.8V到6.0V，具有低功耗CMOS技术，⾃定时擦写周期，1000000次编程/擦除周期，可保存数据100年。
24C02有⼀个16字节的页写缓冲器和⼀个写保护功能。
通过I2C总线通讯读写芯⽚数据，通讯时钟频率可达400KHz。
可以通过存储IC的型号来计算芯⽚的存储容量是多⼤，⽐如24C02后⾯的02表⽰的是可存储2Kbit的数据，转换为字节的存储量为2*1024/8 = 256byte；有⽐如24C04后⾯的04表⽰的是可存储4Kbit的数据，转换为字节的储存量为2*1024/8 = 512byte;以此来类推其它型号的存储空间。
24C02的管脚图如下： VCC和VSS是芯⽚的电源和地，电压的⼯作范围为：+1.8V~+6.0V。
A0、A1、A2是IC的地址选择脚。
WP是写保护使能脚。
SCL是I2C通讯时钟引脚。
SDA是I2C通讯数据引脚。
2、24C02的设备地址和写保护功能 I2C主机在与24C02通讯时，需要发送⼀个设备地址进⾏寻址，在I2C总线上，每⼀个从机设备的地址都是唯⼀的。
24C02的设备地址包含两部分，第⼀部分是bit7~bit4是固定的“1010”，第⼆部分bit3~bit1位由A2、A1、A0组成。
主机在与24C02进⾏通讯时，除了发送设备地址还需要发送数据的读写⽅向位R/W，24C02的是设备地址与R/W位组成了⼀个字节的数据。
如下图： 上图列出了⼏个存储IC的设备地址与R/W位组成的字节。
由图中可以看到，存储IC地址的bit7~bit4位固定为“1010”；bit3~bit1位由A2、A1、A0引脚的电平状态决定，如果Ax接的是电源（⾼电平），那么Ax=1，如果Ax接的是地，那么Ax=0,即由A2、A1、A0可以组合成8种设备地址，也就是说在同⼀个I2C总线上可以同时挂载8个24C02芯⽚。

串行式EEPROM的选用
电子资讯时报/2006年/6月/5日/第A07版器件应用技术串行式EEPROM的选用郭长佑前言谈到串行式EEPROM，相信许多电子电机工程师的心中立刻会生出一个念头：“小儿科、小玩意儿”。
是的，串行武EEPROM确实是一种相当成熟又普通的电子组件，不仅接脚数少(约6pin或8pin)、封装面积小，而且接线设计简单、操作存取也容易，似乎没有值得多谈之处。
话虽如此，但事实上串行式EEPROM依然在持续强化提升，或许这些强化提升无法为现有的设计带来新效益，然而若能在此先有些概念与了解，在日后的新设计中，说不定就能加以发挥取用，以下我们就逐项说明串行式EEPROM的各项新发展趋势。
更高的存储容量与其它并行式内存不同的，串行式EEPROM多是以位(bit：比特)为存储容量单位，例如32Kbit(或写成32Kb)、64Kbit等，而新的发展是让单一封装的EEPROM芯片能有更高的存储容量。
举例来说，法国意法半导体(ST)的M95512-R已达512Kb，或如日本瑞萨(Renesas)的HN58V1001T-25SRE已达1Mb等，都是朝更高存储密度发展的例证。
更活化地调整、变更内存组织如今的串行式EEPROM多半允许设计者自行决定寻址模式，例如要8bit寻址还是16bit，就连每笔存取的数据位数也可自行决定，例如要Byte(8bit)还是Word(16bit)，简单说即是允许设计者自行规划内存的组织(Organization)，且越来越具有弹性。
更低的工作耗电新的发展持续让EEPROM的各项表现都更为省电，包括读出动作要省电、写入动作要省电、无存取操作时的后备(Standby)状态也要省电。
尤其写入操作的电力消耗一直高于读出及后备，所以各企业也优先、积极地强化写入的省电性，其次才努力改善读出的耗电，最后才是后备用电。
更小巧的芯片封装最初的串行式EEPROM是采用塑料DIP封装(PlasticDual-Inline Package，也称PDIP)，为了配合电子产品越来越轻薄短小的设计要求，也开始有更多更娇小的封装可供选择，例如SOP、TSSOP、CSP、DFN、MSOP，以及SOIC等，让应用设计师能有更多适合的选择。
