【选型】国产带电可擦可编程只读存储器 AT24C16M/TR用于电焊机，读写速率高达1MHz
电焊机上面为了在电源撤除后，储存的信息(Data)依然存在，一般会外挂一颗EEPROM存储重要的参数信息，比如存放重要的文件或设备脚本信息，更有甚者会存放一些PID算法的参数信息，那么一颗性价比较好的EEPROM在此类应用中必不可少。本文推荐一颗容量16KB的国产品牌华冠带电可擦可编程只读存储器（EEPROM）AT24C16M/TR，运用于电焊机的应用简易框图如下：
优势如下：
1、供电范围：1.7~5.5V；宽压范围兼容市面上的通用电源电压设计
2、速率：400KHz（1.8~2.7V）and 1MHz（5V），提高主控芯片上电开机时间；
3、 施密特触发器，用于抑制噪声的滤波输入；
4、存储时间：100年，擦写次数：一百万次，可以长时间的使用寿命；
封装引脚图如下：
综上所述：随着国产化需求和高性价比的需求，工程师越来越有意使用国产产品做设计和应用，EEPROM推荐国产华冠推出的EEPROM AT24C16M/TR，读写速率高达1MHz，是电焊机电路设计应用的高性价比解决方案。
