TM4C1233H6PM: USB D+ D- absolute Maximum Ratings

Part Number: TM4C1233H6PM

Hi,

When VDD is 3.3V,   and set PD4, PD5 as USB function

Whats the absolute Maximum Ratings of PD4, PD5?

3.3V+0.3 ?  or 5.5V? 

Thank you.

  • Hi, 

      This is described in the datasheet. Please see below. 

    10.1 Signal Description
    GPIO signals have alternate hardware functions. The following table lists the GPIO pins and their
    analog and digital alternate functions. All GPIO signals are 5-V tolerant when configured as inputs
    except for PD4, PD5, PB0 and PB1, which are limited to 3.6 V.
