5.3.5

Static latch-up (LU)

When running a simple application (controlling the flashing of two LED through the I/O port),

the test sample is subject to false electromagnetic interference until an error is generated, and

the LED flashing indicates the generation of error. In order to evaluate the latch performance,

two complementary static latch tests need to be conducted on 6 samples:

 Provide power supply voltage exceeding the limit for each power supply pin.

 Inject current on each input, output and configurable I/O pin.

This test conforms to EIA/JESD78E integrated circuit latch standard.
