Electrical characteristics
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 three 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.

Class description: A Class is an STMicroelectronics internal specification. All its limits are higher than the
JEDEC specifications, meaning that when a device belongs to Class A it exceeds the JEDEC standard. B
Class strictly covers all the JEDEC criteria (international standard).

Configuration not recommended, all unused pins must be kept at a fixed voltage: using the output mode of
the I/O for example or an external pull-up or pull-down resistor (see Figure 48). Static peak current value
taken at a fixed VIN value, based on design simulation and technology characteristics, not tested in
production. This value depends on VDD and temperature values.
