AURIX™ MCU: Automotive level parameter configuration? – KBA234421

Version: **

Question: In the iLLD and MCAL software code, GPIOs have an “automotive level” parameter configuration. Where to find the description in the user manual?

Answer:

The Automotive level or AL is a standard CMOS level with extended low-level range. The official AL voltage levels can be found in the device datasheet. Main motivation to use extended low-level range is the robustness for ground bouncing and noise in harsh automotive environments.

See the “General purpose I/O ports and Peripheral I/O lines (ports)” section of user’s manual.

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

  • AURIX TC2xx series
  • AURIX TC3xx series
