[STM32H750XBH6] Output current Question

Passerby · ‎2024-05-23

Hello,

I use STM32H750XBH6, DataSheet 'Absolute maximum ratings' say that 'Output current sunk by Px_C pins' is 1mA

What does Px C mean?

Does it mean all the pins of GPIOC?

Or something else?

Thanks!

Px_C does not stand explicitely for Port C, but for special pins that are additionally led out in order to have direct access to the analogue functions. As it happens, in the case of the STM32H750 some of them are part of Port C, are labelled PC2_C or PC3_C and are alternatives with an additional switch to the PC2 and PC3 pins.

Please see RM0433, section 11.3.13, e.g. fig 76 for more information.

Hope that helps?
