Community Translation: AURIX™ MCU: パッドの車載レベル(AL) - KBA234969

Version: **

The pads on the AURIX™ MCU support both Automotive Level (AL) and Transistor-Transistor Logic (TTL) level. The AL is a standard CMOS level but with an extended low-level range.

For example,

The minimum input high voltage level value is 0.7 * supply voltage for AL, 2.0 V for TTL.

The maximum input low voltage level value is 0.44 * supply voltage for AL, 0.8 V for TTL.

This value depends on the product. For more information, see the "Electrical Specification" sections of the datasheet and the "General purpose I/O ports and peripheral I/O lines (Ports)" section of the User’s manual.

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

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
