TMS320F28069M Internal Pullup Resistor

Maxime Torrelli

Hello there!

My question is to know the value of the internal pullup reisitors on the GPIO pins? I can not find it neither in the ddatasheet nor in the Reference Manual.

Tahnks for your help!

Maxime,

From page 150 of the datasheet for the F28069M, we implement the internal pullup resistors for the GPIO pins with the following model:

Additionally, the electrical characteristics for a GPIO pin with the pullup resistor enabled can be found in the table below (also from the same datasheet on page 20)

Let us know if this answers your question or if you have any follow up questions.

Thanks for your help! I did not see this schematics.

Thank you one more time for taking the time to answer my question.
