The length of time an I/O can withstand I
reliability data below is based on a 3.3 V, 12 mA I/O setting, which is the worst case for this type of
analysis.
For example, at 110°C, the short current condition would have to be sustained for more than three
months to cause a reliability concern. The I/O design does not contain any short circuit protection,
but such protection would only be needed in extremely prolonged stress conditions.
