EMC CHARACTERISTICS (Cont’d)
12.7.3 Absolute Maximum Ratings (Electrical
Sensitivity)
Based on two different tests (ESD and LU) 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). Two models can be simulated: Human
Body Model and Machine Model. This test con-
forms to the JESD22-A114A/A115A standard.

each input, output and configurable I/O pin) are
performed on each sample. This test conforms
to the EIA/JESD 78 IC latch-up standard.
