i.MX 8M Mini - GPIO current capability

RobotDR84 — Tue, 02 Aug 2022 18:00:33 GMT

I need to know how much current the GPIO can source and sink.

For example, pins P108 and P109 (GPIO_0, GPIO_1).

The datasheet says the output voltage of the pins was tested at 9.6 mA and held 1.8V (section 3.5, table 21).

But then I see the data sheet says the PVCCx1P8 says 3mA max but I'm not sure what "GPIO pre driver" means.

Thank you for your help.

Hi,

First think, all the pin are categorised into GPIO label(From table 7) and digital I/O are categorised into GPIO pre-driver (PVCC). It's operations range from 1.65 to 1.95 volts 3mA. But table no21 mentioned, all the peripheral which is classified in table 7

Thank you for your response, but I am still a bit unsure of what you're saying.
