Hello,
Whether SPC5200CVR400B is active, obsolete, or discontinued.
This product is end of life.

If this device is still being manufactured. Whether any known issues related to data/software corruption have been reported for this device.
No
Recommended methods to prevent or diagnose such corruption.
I am not aware of any published silicon erratum specifically identifying a generic data or software corruption mechanism for the SPC5200CVR400B.
To investigate potential corruption issues you can:
Perform RAM and Flash integrity checks using checksums or CRCs.
A suitable replacement/alternate part if the device is obsolete or approaching end-of-life.
i.MX application processors - Recommended path for new designs requiring continued product support.
Best regards,
Peter
