Electromagnetic interference (EMI)
Based on a simple application running on the product (toggling 2 LEDs through the I/O ports),
the product is monitored in terms of emission. This emission test is in line with the norm SAE
IEC 61967-2 which specifies the board and the loading of each pin.
Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, DLU and LU) using specific measurement methods, the
product is stressed to determine its performance in terms of electrical sensitivity. For more
details, refer to the application note AN1181.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are applied
to the pins of each sample according to each pin combination. The sample size depends on
the number of supply pins in the device (3 parts*(n+1) supply pin). One model can be simulated:
