I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below V
above V
in order to give an indication of the robustness of the microcontroller in cases when
abnormal injection accidentally happens, susceptibility tests are performed on a sample
basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into the
I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error, out of spec current
injection on adjacent pins or other functional failure (for example reset, oscillator frequency
deviation, LCD levels, etc.).
The test results are given in the following table.

I/O port pin characteristics
General characteristics
Subject to general operating conditions for V
unused pins must be kept at a fixed voltage: using the output mode of the I/O for example or
an external pull-up or pull-down resistor.
