[S32K11x] Does Clamp diodes exist on each pin for S32K11x

[GavinLi1]

Hello Experts,

I just want to clarify that does Clamp diodes exist on each pin for S32K11x as the following picture show?

If yes, where can I can such information from RM or DS?

If no full cover each pin, which pins have the clamp diodes?

Thanks,

Gavin

Hi @GavinLi1,

All pins implement protection diodes that protect against electrostatic discharge (ESD). These internal ESD diodes of the microcontroller are designed just for short discharge pulses only, and these do not sustain a constant current over time.

You can find the ESD and latch-up protection characteristics in chapter 4.8 from the S32K1xx's Data Sheet.

Best regards,
Julián

Hi Julián,
Thanks for your quick reply.

I want to further confirm that the protection diode does real exist not  the equivalent diode or parasitic diode, right?

Thanks in advance!
