I couldn't locate the max current draw on a I/O pin in the Electrical section of the the BCM20736S spec. Does someone know this?

Also, what is the max simultaneous current draw on all the I/O pins combined?

Thank You,

George

Hi George,

I found the below description in 20732S datasheet, I thought it's same with 20736S.

All GPIOs support programmable pull-up and pull-down resistors, and all support a 2 mA drive strength except P26, P27, and P28, which provide a 16 mA drive strength at 3.3V supply.

BTW, you can use the gpio_configurePin() to verify the driver strength.

Currently, we do no have a use case developed which showcases the absolute max. current conditions.
