DS90UB928Q-Q1: What is the push-pull parameter for GPIO output circuit?

Part Number: DS90UB928Q-Q1

Hi Expert,

Could you please tell me the detail of GPIO output circuit. Is this a Push-pull? If so what is the resistor value of R1 and R2? Like below shows.

Best Regards,

Wilson

    Hello Wilson,

    These are push/pull and the internal structure is not really a resistor. To find the characteristics of the GPIO you can refer to the DC electrical characteristics table. For example with 3.3VDDIO the characteristics are here: 

    You can derive "resistance" values based on the short circuit current. 

    Best Regards,
