EMC CHARACTERISTICS (Cont’d)
13.7.2 Electro Magnetic 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 J 1752/
3 which specifies the board and the loading of
each pin.

13.7.3 Absolute Maximum Ratings (Electrical
Sensitivity)
Based on three different tests (ESD, LU and DLU)
using specific measurement methods, the product
is stressed in order to determine its performance in
terms of electrical sensitivity. For more details, re-
fer to the application note AN1181.
13.7.3.1 Electro-Static Discharge (ESD)
Electro-Static Discharges (a positive then a nega-
tive 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). Two models can be simulated: Human
Body Model and Machine Model. This test con-
forms to the JESD22-A114A/A115A standard.
