AURIX™ MCU: Input voltage high and low values for S pad – KBA235362

Version: **

Input voltage high for S pad (VIHS) and input voltage low (VILS) for S pad are as follows:

  1. For AURIX™ TC2xx MCU series:
  • VDDM = 5 V

Parameter

Value

VIHS

(0.73 × VDDM) – 0.25 = 3.40 V

VILS

(0.52 × VDDM) – 0.25 = 2.35 V

  • VDDM = 3.3 V

Parameter

Value

VIHS

(0.73 × VDDM) – 0.25 = 2.159 V

VILS

(0.52 × VDDM) – 0.25 = 1.466 V

 

  1. For AURIX™ TC3xx MCU series:
  • VDDM = 5 V

Parameter

Value

Note/test condition

VIHS

(0.7 × VDDM) = 3.5 V

Automotive level (AL)

2.0 V

TTL level (TTL)

VILS

(0.44 × VDDM) = 2.2 V

AL

0.8 V

TTL

  • VDDM = 3.3 V

Parameter

Value

Note/test condition

VIHS

(0.7 × VDDM) = 2.31 V

AL

2.0 V

TTL

VILS

(0.42 × VDDM) = 1.386 V

AL

0.8 V

TTL

Class S pads are powered by VDDM and can also be 3.3 V and 5 V.

Where,

VDDM = Analog power supply

For more details, see the “Electrical Specification” sections of the TC2xx series and TC3xx series datasheets.

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

  • AURIX™ TC2xx series
  • AURIX™ TC3xx series
