The 96-bit unique device identifier provides a reference number which is unique for any device and in any context. These bits can never be altered by the user.
The 96-bit unique device identifier can also be read in single bytes/half-words/words in different ways and then be concatenated using a custom algorithm.
Base address: 0x1FF80050 for Cat.1 and Cat.2 devices and 0x1FF800D0 for Cat.3, Cat.4, Cat.5 and Cat.6 devices
ST有一个传统:把大容量Flash型号当地容量Flash型号卖(或许是后面Flash有部分坏块、或许是方便批量生产……)
可以用下面这种方式验证一下:
Bits 11:0 DEV_ID[11:0]: Device identifier
This field indicates the device ID.
0x416: Cat.1 device
0x429: Cat.2 device
0x427: Cat.3 device
0x436: Cat.4 device or Cat.3 device(1)
0x437: Cat.5 device or Cat.6 device
