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, 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). This test
conforms to the JESD22-A114A/A115A standard.

JEDEC specifications, that means when a device belongs to Class A it exceeds the JEDEC standard. B
Class strictly covers all the JEDEC criteria (international standard).
DLU
LU
LU: 3 complementary static tests are required on 10 parts to assess the latch-up
performance. A supply overvoltage (applied to each power supply pin) and a current
injection (applied to 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. For more details,
refer to the application note AN1181.
DLU: Electrostatic discharges (one positive then one negative test) are applied to each
pin of 3 samples when the micro is running to assess the latch-up performance in
dynamic mode. Power supplies are set to the typical values, the oscillator is connected
as near as possible to the pins of the micro and the component is put in reset mode.
This test conforms to the IEC1000-4-2 and SAEJ1752/3 standards. For more details,
refer to the application note AN1181.
