Hi.

My customer use PSoC 4100S Plus (CY8C4127AZI-S455).

Please tell us of GPIO drive mode.

Does the maximum current, Output voltage low level and Output voltage high level change depending on the Drive mode?

I understand that the maximum current of GPIO is 25mA.

PSoC 4100S Plus GPIO current

Best Regards.

Hi taas_3144281

I have shared the link of GPIO component datasheet for your convenience. Please go through it for more details about GPIO drive mode.

Please let us know if any further clarifications are required.

Also, to answer your question, the maximum current, output voltage low level and output voltage high level do not depend on the drive mode of GPIO.

Thanks and Regards

Dear Aashita-san

Thank you for your answer.

I understood that these values do not depend on GPIO drive mode.

Best Regards,
