Electrical characteristics

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 J 1752/3 which specifies the board and the loading of each pin.

Absolute maximum ratings (electrical sensitivity)

Based on three different tests (ESD, LU, and DLU) 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: Human body model. This test conforms to the JESD22-A114A/A115A

standard. For more details, refer to the application note AN1181.
