EMC CHARACTERISTICS (Cont’d)

12.7.2 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.

Note:

1. Data based on characterization results, not tested in production.

12.7.3 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.

12.7.3.1 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). One model can be simulated: Human

Body Model. This test conforms to the JESD22-

A114A/A115A standard.
