Question: Is it possible to add inductance or ferrite beads to AURIX™ supply pins?
Answer: In general, using inductance or ferrite beads could improve the EME (electromagnetic emission) behavior of the circuit and reduce the radiation.
The use of inductance or ferrite beads can be inserted in the supply paths at the external regulator output.
No filter components shall not be added into the loop of the internal regulator (e.g., EVR (Embedded Voltage Regulator) -enabled supply pins).
See the EMC and System-ESD Design Guidelines in the application note AP24026.
Note: This KBA applies to the following series of AURIX™ MCUs:
- AURIX™ TC2xx series
- AURIX™ TC3xx series
