ST SPC582B Series, Application Note, Page: 1 / 35

Introduction
This application note describes the FCCU failure input sources. Furthermore, for each of them, it describes how to verify the
integrity of the error reaction path and the recommended methods to inject a fault.
The device mentioned in this document is the SPC582Bx (40 nm–Body–ASIL B). Most of the concepts, however, are also valid
for the other devices belonging to the 40 nm and 55 nm families of SPC5 32-bit automotive MCUs.
Before reading this document, the reader should have a clear understanding about the usage of FCCU. For further details on
this module, refer to “Fault Collection and Control Unit (FCCU)” chapter of the SPC582Bx microcontroller reference manual
RM0403 . For description of the functional and electrical problems of the SPC582Bx devices, the reader should also refer to the
SPC582Bx errata sheet ES0413 .
A reference code is available.
