FLSHID_CUST_TABLES_FAB_YR的说明

我们检查一下，最早回来。



     以下为原文
  We will check this and come back at the earliest.

“文件中提到的一年：0－9”指的是一年中4的最后一个数字。
这就是我所担心的…：
另一个问题是：批次号（寄存器0x49000103-4U）在产品生命周期中对于每个批次都是唯一的，还是每X年重复一次？如果它们是唯一的，我们可以使用它们来识别属于同一批次的PSoC，即使我们的产品已经运送了很多年（寿命10年）。



     以下为原文
  "The "Year: 0-9" mentioned in the document refers to the last digital of the 4 of a year"
That's what I feared... :/
An additional question: are the lot numbers (registers 0x49000103-4u) unique for each lot over the product life cycle or do they also repeat themselves every x years? If they were unique, we could use them to identify PSoCs belonging to the same lot even after our products have been shipped for many years (lifetime > 10years).

PSoC Creator在Cylib为用户提供了一个全局API CyGutUnQuiuID（UTI32×UnQuIDID）。PoSoC／4/5项目的C，功能注释提供了您关心的信息。
但是请注意，“CyPress还没有实现一个业务流程，以确保编程到这些字节中的值是无错误的”。因此，如果您必须承诺每0%个产品的绝对唯一ID，这个工厂独特的ID可能不适合您的设计。

  David,
 
PSoC Creator provides user a global API CyGetUniqueId(uint32* uniqueId) in Cylib.c of PSoC3/4/5 project, function comment provide the information you concern.
 
But please note that "Cypress has not implemented a business process to ensure that the values programmed into these bytes are error free". So, if you MUST promise an absolutely unique ID for each product with 0% error,  this fab unique ID may not suitable to your design.
