6.11.3 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, refer to the application note AN1181.
6.11.4 Electro-Static Discharge (ESD)
Electro-Static Discharges (3 positive then 3 negative pulses 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 Charge Device Model. This test conforms to the
JESD22-A114A/A115A standard.

Data based on characterization results, not tested in production.
6.11.5 Static and Dynamic Latch-Up
●
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: Electro-Static 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.
6.11.6 Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations:
The software flowchart must include the management of runaway conditions such as:
●
Corrupted program counter
●
Unexpected reset
