STM32G0 input structure and clamping diodes - especially in analog mode

0690X00000AAQfdQAH.jpgHi,

published io port structure in STM32G0 reference manual does not show input clamping diodes.

So: Need to provide them externally ?

Or: Bug in io port sketch ?

Best regards

Juergen​

​Hello

here after the correct structure for TT and FT GPIOs

For more details concerning the STM32 GPIOs don't hesitate to look at the Application Note  AN4899   "STM32 GPIO configuration for hardware settings and low-power consumption" .  This A.N. is available on the web st.com

Best regards

​No one ?

Is G0 gpio the same as L0 gpio ?

Other STM32 manuals sometimes state that images are symbolic, i.e. show just functional elements.

Very little information about implementational details like clamping diodes.

You would need to ask ST - or wait until competent ST staff bothers to answer here.
