Community Translation: AURIX™ MCU: 3.3V外部電源であるときに、Flextportピンを5Vで使用すること - KBA235618

Version: **

The Flexport (VFLEX) pins can be supplied with 5 V only when the external supply (VEXT) is 5 V. So VFLEX can not be supplied with 5 V when VEXT is 3.3 V.

For more details, see the “System Control Unit (SCU)" related to AURIX™ TC2xx devices, “Power Management System (PMS)" related to AURIX™ TC3xx devices sections of the User’s Manual.

Note: This KBA applies to the following series of AURIX™ MCUs:

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
