EEPROM write protection Andyjety Level 3 Jump to solution Hi we have been using CY8C3866LTI-067T as our IoT device for ADC data collection for years. But we faced an EEPROM problem sometimes. the data in the EEPROM could be erased or reset. is there any possible reason for that?

According to the write protection circuit, a CSP packaging EEPROM still has a write protection function under the condition of no WP pin, noise interference can be effectively resisted, and the problem of write protection failure of the EEPROM can be effectively and completely solved; in addition...
Linux系统中的写保护技术(write protection)是一种非常重要的安全机制,它可以有效地防止恶意程序对系统进行未经授权的写操作,保护系统的稳定性和安全性。在Linux系统中,写保护技术主要通过文件系统的权限控制和内核的访问控制来实现。 文件系统是Linux系统中的一种基本组件,它通过文件和目录的权限设置来控制用户和进程对...

读取每个写缓存。确认只有一个缓存不是可用状态。如果只有一个缓存含有未定义的状态代码,则返回一个写操作中断(interrupted write)错误代码。如果所有缓存均包含未定义的状态代码,则返回EEPROM未初始化(uninitialized EEPROM)错误代码。 如果仅有一个缓存包含占用状态代码,计算此缓存的CRC。如果CRC不匹配,则返回一个写操作...
