Static latchup
Two complementary static tests are required on six parts to assess the latchup
performance:
●
●
These tests are compliant with EIA/JESD 78A IC latchup standard.
Electrical sensitivities
I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below V
above V
operation. However, 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 above a certain limit (>5
LSB TUE), out of spec current injection on adjacent pins or other functional failure (for
example reset, oscillator frequency deviation).
The test results are given in
