汽车常见EEPROM芯片浅谈 就汽车上常见的EEPROM芯片按其接口方式来分，无外乎有I2C、Microwire、SPI三种，但每一种芯片又分为各种容量规格，比如I2C中的24C01、24C02、24C04，一般尾数大的比尾数小的容量大，且有着直接的倍数关系。其中汽车音响用的芯片种类最多、最杂，从I2C的24C01－24C16，Microwire的93C06到93C56，现在出的音响还用到SIP的25160，而且Ｍirowire的93C46系列还分为标准与非标准，二者主要体现在引脚分布上，其内部功能基本一致。使用时须仔细区分，否则出现读写不了数据还误认为芯片损坏，主要是***的汽车音响会用到这种芯片，欧美的音响基本不采用这种“非准”芯片。另外还有一种S130和S220的芯片，它们分别对应93C46和93C56，在欧洲产的音响还会经常见到85C52的芯片，通常为贴片封装，外型比一般的贴片芯片要宽一些，它和24C02基本一样，但其第7脚的写保护和24C02的写保护引脚电位状态是反的，85C52是高电位有效。在较老的奔驰音响还可常见到BAW574252，它也是和24C01一样的，24C01有的芯片会出现能读不能写数据的情况，这时可用一片新的24C01或24C02代替。24C02可完全兼容24C01所有功能。
在液晶仪表上用的芯片相对来说就要规范得多，大多采用Microwire，从93C46到93C86都有采用，基本上没有“非标准”芯片，且大多采用16bit结构，读取数据时须注意是16bit还是8bit，否则会出现高低位颠倒甚至数据错误的结果，这是调表须特别注意的事。在新款的奔驰也常见24C04和B58芯片，B58可以用93C56代替。但读写数据时，须把第七脚置为低电位。稍老的宝马常用到CS56、CS66，它们也须把第七脚置为低电位。在国产的仪表还用到SPI的25010和X25043（X5043），上海别克和时超用的ATMEL68343A，其实就是25010。在丰田的4700吉普车上还用到S220，它等同于93C56。
在大众的车身防盗芯片有93C46、93C56、93C86几种，其中进口老奥迪用93C46（8bit），时超用93C56（老的用8bit，新的用16bit）C5A6、PASSAT、BORA等用93C86（16bit ）。
另外在气囊电脑、波箱电脑、遥控门锁电脑也会用到这些芯片。在很多不得已的情况下（比如波箱锁档，没有原厂诊断电脑），我们也可以通过直接读写EEPROM数据来进行维修工作。

你应该了解一些常识,对工作有帮助.例如,买家问,本田刹车好还是丰田刹车好?
你如果能讲出两者ABS的区别,买家就信任你了,当你是专家,你卖车多了,奖金就多了. 我是汽修的`````也看不懂````
以后靠什么吃饭啊```
汽车电路那些最复杂了````LZ能告诉我怎么办吗````
回复 6# 再说一次小真真 的帖子
1,搞清楚汽车结构和机械动作原理.轮子怎么动?怎么停?方向怎么转?发动机怎么运转?................2,汽车的机械动作,以前靠人操作.如果有电脑控制,会怎样?让你做主,你认为电脑应该有什么功能?这些功能要什么电路完成?
3,现在已经有汽车电脑,你先搞清楚汽车电脑功能和结构,和你想象的有什么区别?
如果和你想象的一样,很好!你是天才,你懂了!再想想,汽车电脑还缺什么?有那些地方要改进?你会成长为专家.
如果和你想象的不一样,你先接受并弄懂它,再和你的想法比较,为什么不同,它什么地方先进?有什么地方要改进?你同样会成为专家.
献丑了. 俺是电子的....

技术.因为不明,所以要学.
因为少人懂,更加要学.
如果卖菜的啊婆都懂的,学来没用了.
