Tool/software:
Do all I/O lines have internal clamping diodes to ground and VCC?
Hello Abdulkader,
As seen from datasheet section 7.1 Absolute Maximum Ratings, there is a few fail-safe pins and most I/O aren't fail-safe.
Voltage must never exceed absolute maximums.
Please refer to Chapter 7 in the Datasheet for details.
Thanks,
Stan
So that means that except for fail safe io pins, the rest of Io pins have the clamping diodes. Based on this Article by TI, is this correct? Clamp diodes: A one-way street
