    About VBUS of PSoC4

    YaKu_1055906

      Hi all,

       

      I will use CY8C4247LTI-L475.

      I have a few questions about VBUS of CY8C4247LTI-L475.

       

      [1]

      Could you tell me about the difference between Vusb_3.3(SID322) and Vusb_3(SID323)?

      I don't know "Functional operation only".

       

      [2]

      The max voltage of Vusb_5(SID321) is described as 5.5V in data sheet.

      Is this 5.5V the absolute maximum ratings?

      (Depending on the battery, 6V may be applied to VBUS.)

       

      [3]

      The max voltage of Vusb_3.3(SID322) is described as 3.6V in data sheet.

      Is this 3.6V the absolute maximum ratings?

      (Depending on the battery, 4.2V may be applied to VBUS.)

       

       

      Best regards.
