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: 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.
