Unique Identification of different variant of S32K144

Hi NXP,

We are using three different variant of S32K144 microcontroller in production.

1. FS32K144UAT0VLHT

2. FS32K144HAT0MLHT

3. FS32K144HAT0VLHT

Is there any chance that these different variant have same UID number(SIM->UIDH/MH/ML/L)?

Hi

The 128-bit unique identification number is loaded into IFR during manufacturing process and it is set for each device as identifier of the device and placed into our internal records about device.

Even different variants will not have the same 128-bit unique identification number.


Best Regards,
Robin
